Abstract

During the past three years, tremendous efforts have been made to tackle the Coronavirus Disease 2019 (COVID-19) crisis, including centralized quarantine, compulsory testing, and sweeping lockdowns. The measures have taken effect, but have caused a huge burden on healthcare systems and significant disruption to global economies on an unprecedented scale. Recently, some countries and regions have observed signs of the pandemic resurgence. To better handle the resurgence in the post-COVID era and future pandemics, an immediate revolution of the precise and rapid responding system capable of early detection is needed. Based on a comprehensive review, this article summarizes the enabling wearable devices in physiological monitoring and biomolecular diagnosis, highlights their potential contributions to the detection and management of COVID-19, as well as its long-term effects, and suggests a wearable sensing-based system to avoid future pandemics. Wearable devices, in conjunction with mobile health (mHealth) technologies, provide a novel way to track and monitor diseases through continuous physiological, physical, and biomolecular sensing. Augmented by artificial intelligence (AI), especially the emerging Generative Pre-trained Transformer (GPT) algorithms, patients could potentially be identified before they become symptomatic. By combining contact tracing and effective quarantine, it is possible to arrest the spread of the disease and control its emergence at an early stage. Furthermore, with minor refinements, the proposed response system holds the potential for extended use beyond COVID-19, particularly in addressing cardiovascular diseases (CVDs) during both outbreaks and non-pandemic scenarios. By implementing this groundbreaking approach, there exist valuable prospects to transform the current healthcare paradigm and drive significant advancements in disease prevention, detection, and management.

INTRODUCTION

The COVID-19 pandemic has had a profound and far-reaching impact on the world since it emerged in 2019. According to the latest statistics from the World Health Organization (WHO) on 9 August, 2023[1], over 769 million confirmed cases of COVID-19 and approximately 6.9 million fatalities have been reported. The outbreak has threatened global public health and the economy over the past three years. There have been some changes in public perception and policy, such as the WHO's acknowledgment that a zero-COVID strategy is unsustainable[2] and the lifting of compulsory quarantine. Nonetheless, the emergence of viral varieties and the long-term effects of infections[3] show that it requires continuous attention and management. Particularly in China, the COVID-19 resurgence has meant three-quarters of Chinese people who were not infected in the initial wave were infected in subsequent waves[4].

The severity of the crises resulting from the COVID-19 outbreak and its resurgence highlights the urgent need for swift responses and anticipatory solutions in combating highly contagious diseases. Initiatives such as the proactive global eco-social pandemic preparedness system[5] and a technical framework[6] for reacting to COVID-19 have been presented. Though some researchers have developed models to understand the current and future pandemics[7], society still faces grand challenges in predicting the occurrence of future pandemics, and how likely they will affect the health of human beings.

For successful early prediction and management of pandemics, the implementation of self-reporting of symptoms and routine monitoring has been a key tenant. To promote adherence and ensure wide adoption of a monitoring approach, there is a significant demand for straightforward and portable tracking technologies capable of monitoring vital physiological, biochemical, molecular health metrics and disease indicators. These requirements can be effectively addressed by wearable devices. Wearables are being increasingly integrated into clinical practice to support health assessment and early detection, becoming more prevalent not only for individual and home use, but also in clinical settings[8]. Therefore, it is essential to incorporate Internet of Things (IoT) assisted wearable health sensors into the response and management systems to identify anomalies, detect emerging patterns and predict the likelihood and localization of a disease outbreak before it becomes widespread.

Several comprehensive reviews have been conducted regarding wearable technologies on COVID-19. Many of them lack the perspective of molecular testing supported by wearables[9-13], which plays a crucial role in achieving early detection, especially if it could detect low virus loads before infected individuals become contagious. Our study covers wearable molecular testing to support combating the current COVID-19 circumstance and possible future pandemics. Furthermore, our study emphasizes a wearable sensing-based precise and rapid responding system, leveraging state-of-the-art GPT algorithms to evaluate multimodal data, especially from wearables, to provide personalized suggestions and prompt responses. Existing studies either primarily focus on the early detection, assessment and monitoring of COVID-19[9,10], or on managing long COVID conditions[11]. The review from Ding et al. categorizes enabling wearable technologies by symptoms and telehealth technologies for the remote monitoring and diagnosis of COVID-19[12]. Adans-Dester et al. discusses the significance of mHealth technologies and their integration to mitigate the effects of the COVID-19 pandemic[13]. Compared with the aforementioned works, the present study not only provides a summary of wearable technology applications in the early detection, diagnosis and monitoring of COVID-19, but also highlights their role in managing long COVID. Our proposed response system involves the emerging GPT algorithms and several mHealth technologies for addressing COVID-19 and future pandemics, and can be extended to tackle other diseases with minor modifications.

In the envisioned system, wearable devices play a crucial role in tracking physiological health data and potentially even detecting related molecular biomarkers associated with a disease. Furthermore, the suggested system will deliver remote healthcare services and facilitate population monitoring, particularly for high-risk groups. By reviewing the applications of mentioned technologies, we aim to shed light on how they can assist in the early detection and monitoring of outbreaks. Lastly, the aforementioned wearable sensing-based responding system is proposed as a promising solution to address the prevailing challenges encountered in pandemic prevention, early detection and effective management, ultimately enhancing our ability to be better prepared and to respond effectively to such crises in the future.

WEARABLE TECHNOLOGIES FOR COVID-19

As stated in several studies[14-18], fever, respiratory abnormalities, fatigue, muscle pain, headache, and other cardiac complications are common in pre-symptomatic cases, symptomatic cases, and post-COVID-19 patients. Wearable devices, aided by mHealth technologies, are critical technologies necessary to continuously track and monitor diseases through physiological, physical, and biochemical sensing. The COVID-19 pandemic has further advanced this field. Being able to collect relevant physiological data and self-reported symptoms, wearable devices were suggested to be included in COVID-19 management for detecting infectious cases, reducing disease transmission, facilitating early intervention and monitoring long-term effects. Several wearables for COVID-19 are summarized in Table 1.

Wearables for detecting early signs of COVID-19

COVID-19 patients may be contagious 48 h before starting to experience symptoms, i.e. while being pre-symptomatic or asymptomatic[61]. Laboratory data from WHO demonstrated that the highest level of infectivity occurs just before symptom manifestation and during the initial phases of the disease[62]. Consequently, timely detection of early signs of COVID-19 may not be sufficiently rapid to identify infected individuals before they become contagious. However, early identification of the infection could help in immediate intervention and controlling the further spread of the disease, particularly during the incubation stage. Figure 1 summarizes a wide range of wearables, including smartwatches, finger rings, face masks, earbuds, wristbands, armbands, smart textiles, and patches, for evaluating the early signs or clinical symptomology of COVID-19.

Figure 1. Different types of wearables for detection of mentioned symptoms.

Some findings demonstrated that temperature could be used as a superior indicator for COVID-19 detection before individuals become symptomatic[19,34]. Fever is one of the most common symptoms observed in over 50% of infected patients[63]. Commercialized wearables such as wristwatches/bands (GOQii, GOQii Technologies Pvt Ltd, United States)[21] and armbands (Everion, Biofourmis, Switzerland)[22] can measure temperature continuously. Studies conducted by the University of California using Oura Ring (ura Health Oy, Finland) suggest that data changes 76% of the time before users feel symptoms of COVID-19[19,64].

Abnormalities in respiratory symptoms, such as dry cough and shortness of breath, have been demonstrated to be one of the earliest signs of COVID-19 infection[65]. To detect variations in respiratory activities, several innovative wearable approaches based on chest/throat vibrations[24,29], air pressure/vibrations[23], acoustic sensing[25,35], ultrasound[66], or others[30] have been developed. One such example is the Rogers team's[24] soft, skin-integrated, high-bandwidth, accelerometer-based monitoring patch attached at the base of the neck, offering continuous readings of respiratory rate (RR), coughing, body temperature, etc. Several researchers integrated sensors on face masks for detecting air pressure/vibrations for respiratory monitoring[23,28]. Additionally, nasal respiratory sensors are widely explored[30,67], one of which is capable of simultaneously capturing multiple self-calibrated breathing parameters (such as respiration depth, apnea-hypopnea index, and peak expiratory flow) for evaluation[30]. Respiratory activities including RR and cough patterns can be measured and identified by utilizing a smartphone[26], stethoscope[35], or an acoustic sensor[25]. Several respiratory monitoring systems, such as BioButton (BioIntelliSense, Inc., Australia)[32], have been commercialized. Additionally, blood oxygen saturation level (SpO2) is an important indicator for early warning, triage, and monitoring of COVID-19 patients[68]. There are numerous pulse oximetry devices based on optical sensing available in the market, especially worn on the wrist and fingertip from companies such as Apple (Apple Inc., United States), Huawei (Huawei Technologies Co., Ltd., China), and Samsung (Samsung Electronics Co., Ltd., South Korea)[36]. Even though the technology is well-established, various studies continue to investigate SpO2 measurements via flexible patches, earbuds, and fingernails[38-40].

According to the report from Columbia University’s Division of Cardiology in New York, the virus injures the heart, probably by either attacking it directly or causing a cytokine storm that leads to myocyte apoptosis[69]. Cardiac symptoms can be the first sign of COVID-19, with reports from China documenting patients who experience palpitations and chest pain without the typical fever and cough[17]. Therefore, the monitoring of certain cardiovascular indicators, such as electrocardiogram (ECG), heart rate (HR), and blood pressure (BP), is of critical importance. To assess early cardiovascular involvement in COVID-19 patients, ECG is a widely used clinical method. Various abnormalities in ECG such as ST- and T-wave changes, arrhythmia and myocardial infarction have been reported in COVID-19[70]. One study presented a cognitive dynamic system (CDS)-based framework, which is able to automatically identify people having arrhythmia from single-lead ECG traces[71]. Some special designs such as non-contact wearable wireless ECG systems based on capacitive-coupled active dry electrodes are also proposed[72,73]. ECG wristbands and chest patches are frequently used for wearable ECG monitoring, most of which are commercially available and have received FDA certification. However, both patch electrodes and wristwatches/bands are mostly single lead systems, which may not be enough to detect cardiac abnormalities, especially myocardial infarction. Many investigations have been carried out to produce multiple-lead ECG monitoring[41,42]. One such example, using a graphene/PDMS dry electrode material, has recently attracted attention as it is stable, washable, flexible, and reusable. The integrated electrode provides a novel strategy for wearable 12-lead ECG monitoring and could be extended to professional EEG and EMG monitoring[42].

COVID-19 can cause increases or irregularities in HR in response to fever or inflammation[74]. The smartwatch is already being used for HR monitoring. One study analyzed the resting HR data collected from 1,265 individuals, which could distinguish between COVID-19-positive and negative cases as early as 10 and 5 days prior to a diagnostic test[75].

Even though fatigue is a less well-known symptom of COVID-19, it is one of the early signs of the disease and more common than the “classic” symptoms of cough and fever[15]. Additionally, pain is also one of the early signs of coronavirus infection, especially headaches and muscle aches[16]. There are various products or prototypes in the form of glasses[55], patches[54], and earbuds[56] to evaluate fatigue levels and pain perception. Particularly, Northwestern University researchers developed a soft, flexible, postage-stamp-sized wearable device that comfortably adheres to the upper chest to evaluate vocal fatigue and provide real-time feedback[54]. These technologies could be potentially useful for detection of early signs of COVID-19. Several selected wearable devices with potential applications in COVID-19 and the representative results are presented in Figure 2.

Despite the fact that accurate and fast early detection of COVID-19 by molecular testing has not yet been accomplished, there has been considerable research into prediction and early detection of the disease using mathematical and computational models with AI assistance[78,79]. Some studies and products use information from abnormalities/variations in physiological features to identify COVID-19 prior to the symptom onset or in asymptomatic cases. These features include analysis of RR[65] and wristwatch data (HR, daily step count, or sleep duration)[80]. Available products include the European CE-marked Empatica smartwatch (Empatica Inc., Italy)[81] and the FDA-approved armband Tiger Tech COVID PlusTM Monitor (Tiger Tech Solutions, Inc., United States)[82,83].

Wearables for molecular detection

Some existing methods documented that they could identify pre-symptomatic or asymptomatic cases, while the concern is that even without COVID symptoms, individuals may be infectious, making immediate detection and confirmation of COVID-19 before transmission extremely difficult. In light of this, a study conducted by a team from Harvard University and MIT developed a synthetic biology sensor (lyophilized CRISPR sensor) placed into a face mask. Thus, the sensors are able to detect SARS-CoV-2 noninvasively at room temperature in less than 90 min. The face mask sensor demonstrates a detection limit of 500 copies (17aM) of SARS-CoV-2 in vitro transcribed (IVT) RNA, equivalent to the detection limit of WHO-endorsed standard laboratory-based RT-PCR assays, while also exhibiting no cross-reactivity to RNA from other commonly circulating human coronavirus strains (HCoVs) [Figure 3]. These sensors can be integrated into garments with sensing electronics and wireless networking capabilities for real-time dynamic monitoring of target exposure[84,85]. Though the sensitivity and selectivity are highlighted, the results might not be rapid enough to prevent transmission, typically before they engage in crowd gatherings or other high-risk social activities. Another work from Cao’s team at Peking University[86] could predict key mutations by studying antibodies from people who had recovered from the earlier variants.

Although wearables for continuous physiological and physical sensing aided by AI have shown promising advancements in detecting early signs of COVID-19 or even identifying the virus before symptoms appear, they are limited by the uncertainty of infectiousness. To truly achieve early detection, there is a need for further exploration and integration of wearable devices with highly sensitive biochemical sensors capable of detecting low virus loads even before infected individuals become contagious. These sensors should be developed and incorporated into a wearable format to enhance their usability and practicality for real-time monitoring and early identification of COVID-19 cases before the subjects become contagious.

Wearables for monitoring of COVID patients

Those who received a positive COVID-19 test were more likely to have similar symptoms as pre-COVID cases, whereby their health status can be tracked and monitored continuously and remotely by the summarized wearable technologies above.

High blood pressure (BP) has been identified as one of the most common comorbidities and risk factors for severity and adverse outcomes in COVID-19 patients[87]. Another large observational study reported a small but consequential rise in average BP among US adults during the COVID-19 pandemic, which could significantly increase the number of strokes and heart attacks in the general population[88]. Cuffless BP monitoring devices are crucial for BP monitoring because they can readily provide continuous, real-time monitoring. Several commercialized cuffless BP wearable products are available, such as Biobeat (Biobeat Technologies, Israel)[48] and Valencell (Valencell, Inc., United States)[49], worn on the wrist and fingertip, respectively, for beat-to-beat BP monitoring. Other than these, some researchers explored unusual sites such as in the ear[53], finger proximal phalanx[77] and fingernail[50], as well as new approaches such as multiwavelength photoplethysmography (PPG)[89]. In order to improve the wearing conformability and unobtrusiveness, several biocompatible sensors such as silk nanofibrous iontronic pressure sensors[51] and graphene bioimpedance tattoos[52] are in development for skin-friendly longer-term BP measurement.

Difficulty breathing, inability to wake or stay awake, and cognitive dysfunction are also reported as severe situations in COVID patients[14]. Some studies investigated the associations between cognitive dysfunction and physiological signals such as HR, temperature, and skin conductance and behavioral signals, which can be monitored using embedded sensors from wearables like the Microsoft Band 2 smart band (Microsoft Corporation, United States)[58] or from simpler wireless peripherals such as PPG devices[90]. With the purpose of facilitating symptom monitoring and sleep disorder identification, a wearable shirt was devised[57]. Another approach used a wrist-worn Actigraph (ActiGraph, LLC., United States)[58], which can track both waking and sleeping hours. The behind-the-ear wearable technology by Pham et al. may concurrently detect sleep and fatigue[59]. All of them can be potentially used in COVID scenarios.

Infected patients typically manifest a combination of at least two symptoms instead of a single symptom[63]. However, the need to wear several sensors to obtain multiple related signals is not an ideal approach as it will lead to poor compliance and has the potential for compounded readout errors due to errors in sensor placement and misuse by the end-user. Alternatively, it may be possible to extend sensor or system functionality by innovative multimodal design to obtain multiple signals simultaneously. Furthermore, with advantages in novel material and fabrication technologies, developing flexible, stretchable, self-adhesive, lightweight wearable sensors is gaining increased attention [Figure 4]. Multimodal sensor design can extract more sophisticated information, while flexible sensing is advantageous for achieving precise, unobtrusive, long-term monitoring. This integration enables the detection of unusual disease patterns or clusters of symptoms, thereby providing early warning signals for potential pandemics.

Wearables for long COVID

The WHO reported that a significant proportion of individuals infected with COVID-19, ranging from 10% to 20%, may continue to develop long-COVID sequelae[18]. Since COVID is a multi-organ disease, there is a growing awareness of how to manage these ongoing health issues. Apart from the commonly observed symptoms such as fatigue and cough[92], emerging evidence from various reports highlights an increased incidence of psychological and psychiatric disorders among individuals who were infected. These include sleep disturbances both during and after the pandemic[93-95]. It is crucial to effectively manage these wide-ranging health consequences associated with COVID-19, extending beyond the acute phase of the illness.

With the rise of wearables, it is important to evaluate the long-term effects of COVID-19, particularly on sleep patterns, by using wearables. Some researchers have utilized PPG-based wearable devices to analyze sleep phases, and certain biometrics are highly related and can reflect sleep patterns[96]. Furthermore, machine learning algorithms have been developed using the relationship between biometrics (e.g., HR and HRV) and sleep cycles to define sleep phases[97,98]. Mekhael et al. used wearable PPG-based wristbands to detect RR and SpO2 to assess the long-COVID effects on sleep patterns[99]. The Oura ring that has been evaluated against polysomnography (PSG), the gold standard test used in sleep labs, can also be used to monitor post-COVID insomnia[60]. Moreover, the risk of long COVID may lead to life-threatening conditions. For example, a significant drop in SpO2 levels (less than 95%) may cause brain damage, heart failure, or even sudden death[11], which can be monitored by wearable devices.

Long COVID-19 encompasses various unknown factors and the management and treatment approaches for this condition are still in their early stages[100,101]. Although several studies acknowledged that wearables could be a viable solution for recognizing long COVID and emerging infections, long COVID involves a spectrum of cardio-neuro effects, such as brain fog, insomnia, dizziness, and blood lipid abnormalities[102]. Therefore, wearable devices alone are insufficient to identify and manage long COVID patients. Rather, they should be supplemented with imaging tests (chest X-rays, CT scans), pulmonary function tests, hematological assessments, etc.

Personalized AI Doctor (Doctor PAI)

The widespread use of AI has been facilitated by the abundance of complex big data in the healthcare industry[103], particularly in the context of the ongoing COVID-19 pandemic and future outbreaks. Numerous studies have demonstrated that AI is capable of performing or even outperforming humans in several healthcare-related tasks, such as analyzing vast amounts of medical data to provide diagnoses and identifying patterns that may not be immediately apparent to human healthcare professionals[104]. It is anticipated that AI will eventually change the remote healthcare domain with applications in teleconsultation, rehabilitation, health management and other areas as a fundamental tool driving the advancement of precision medicine. The application of AI is suggested for the fight against COVID-19 and can be used for early warning systems, ongoing monitoring, diagnosis and prognosis, therapy, and even drug design, as well as control over society and individuals via regulations. Several AI-based models, such as BlueDot[105] and HealthMap[106], have been developed and were shown to be capable of predicting infectious pandemic diseases. Moreover, Bluedot predicted the COVID-19 threat before WHO officially recognized it at the end of December 2019[107].

Recently, GPT described algorithms, such as ChatGPT, have attracted much interest in clinical medicine[108-110]. ChatGPT was able to manage complicated medical and clinical information[111], and passed the US Medical Licensing Test without clinician input[112]. When ChatGPT was asked what specific information would enable early diagnosis, control and management of COVID-19, the responses clearly mentioned that the integration of health data collected from wearables can provide additional insights for personalized preventive measures. Furthermore, to answer the question of “What kind of system would you suggest for the early detection of future pandemics?”, ChatGPT proposed to implement a comprehensive system encompassing a global surveillance network, advanced data analysis, integrated healthcare systems, etc., with a focus on global collaboration, information sharing, advanced analytics and early intervention. With such a system, it would be feasible to identify and respond to infectious diseases promptly, implement appropriate control measures, and effectively manage the initial phase of transmission. However, it should be noted that the provided suggestion lacks specific technical details and operational guidelines. When asked the technical question regarding the role of physiological and molecular sensing, ChatGPT recognizes the crucial roles of physiological and molecular sensing in the forecasting and timely identification of future pandemics, especially in providing valuable contributions in disease biomarker identification, rapid diagnosis, wearable devices, syndromic surveillance, remote monitoring and telemedicine, early warning systems, among others, as outlined in Appendix Table 1 as an Appendix. The full responses emphasized that by processing comprehensive and up-to-date information on different aspects such as symptoms, contact tracing, and integrating wearable health data, they could provide valuable data for surveillance, diagnostics and public health interventions, ultimately helping to mitigate the impact of pandemics on global health. These insights align closely with the proposed responding system we have introduced.

It is expected that the infection risks can be reduced by the development of a Doctor PAI system that integrates and evaluates multimodal data from wearables, medical imaging, molecular tests and contact tracing, leveraging a GPT model to provide personalized and fast responses to users' health-related inquiries. Upon utilizing the proposed Doctor PAI system, the data is uploaded to a cloud-based storage bucket and processed by the Doctor PAI, which utilizes both GPT and AssemblyAI to interpret textual and voice messages. The pre-trained GPT model is stored in a Lambda function on the cloud, enabling it to handle user queries and retrieve relevant information from the database. The system is designed to be scalable and capable of managing large volumes of data while concurrently ensuring user privacy and data security. By deploying on wearables, smartphones and other platforms, the benefits of Doctor PAI for general populations include professional medical advice, AI-assisted living, and homecare, allowing for tele-consultations, tele-monitoring, tele-diagnosis and even tele-intervention as depicted in Figure 5. Furthermore, Doctor PAI might arm caregivers with powerful tools for a more thorough evaluation, a precise and prompt diagnosis, and specialized COVID patient care, simultaneously alleviating the workload of healthcare professionals and enhancing overall medical efficiency.

Figure 5. The overall design of Doctor PAI and schematic representation of how to utilize Doctor PAI. Textual or voice messages of inquiries, symptoms, personal information and medical history from the user (or from the medical institution) can be interpreted by Doctor PAI. These data are subsequently analyzed by current GPT technologies to obtain potential diagnoses. Together with physiological health data collected from wearables, available medical imaging, DNA testing and blood testing data from medical institutions, Doctor PAI integrates and evaluates the multimodal health data to deliver personalized and prompt responses.

Smart conversational agents (chatbots), including ChatGPT, are currently being widely debated due to both the advantages highlighted above and the disadvantages described next. Indeed, utilizing AI in clinical diagnosis in real-world implementation presents some pitfalls. One such pitfall is that the GPT models are limited by training on a general information database instead of a specific medical database. ChatGPT does not source information in the traditional sense and cannot evaluate its output’s reliability. Instead, the model relies on the likelihood of phrases and sentences going together rather than by reference to specific knowledge bases. This limitation may result in inaccuracies and pose a strong safety concern[113]. Correspondingly, AI cannot serve as a substitute for healthcare providers due to the inherent risk of outdated or biased information when information sources are not consistently updated or not heterogeneous. The consistent use of ChatGPT for diagnosis by physicians may lead to a decline in their diagnostic capability and overreliance on technology[108]. Furthermore, a significant concern arises from the absence of accountability regarding medical accidents and associated errors. This gap can be exploited by persons with malicious intent to develop substandard products or to acquire patients' personal information. Notwithstanding its inherent challenges, GPT technology showcases numerous advantages and possesses significant potential applications. If employed appropriately, in the future, this may represent a groundbreaking and innovative approach that has far-reaching implications for traditional medical systems, expanding its potential applications to various diseases beyond COVID-19.

WEARABLE-BASED PRECISE AND RAPID RESPONDING SYSTEM

According to the WHO, the early infectious period of COVID-19 without recognizable symptoms is around 2-3 days[62]. If the signs/signals could be caught in that time window together with immediate quarantine, it would significantly reduce disease transmission. For this, a wearable-based precise and rapid responding system is proposed [Figure 6]. It is easily accessible to the public, with the benefits of early detection and long COVID monitoring for better management of future pandemics or long COVID.

Towards wearable sensing-based precise and rapid responding system for the early detection of future pandemic

Figure 6. The proposed wearable-based precise and rapid responding system.

In the proposed system, the use of wearables would enable real-time physiological signals/metrics and biochemical markers monitoring[81,84,114]. With continued innovation, several wearable-based mHealth technologies could be developed with contact tracing applications[115-118]. This is considered to be the first and most effective step to prevent an outbreak when the medical resources are unavailable for immediate utilization[119], allowing for the tracing of people and assessing the possibility of infection via contact with other suspected individuals or individuals who tested positive. Users can conveniently access their health data through wearables or mobile devices wirelessly. Furthermore, a feasible real-time wearable system with a control panel and a vital-sign data display can be remotely operated by authorized healthcare professionals. It is important to strengthen trust and improve the accuracy of remote monitoring through collaborative efforts with clinicians, such as proposing clinician dashboards in wearable systems[120]. In addition to the above-mentioned technologies, the Centers for Disease Control and Prevention (CDC) launched the National Wastewater Surveillance System (NWSS) in September 2020 to provide an early warning of COVID-19’s spread in communities[121]. States and municipalities such as Hong Kong monitor wastewater effluent to assess viral emergence and resistance[122]. Due to the difficulties in predicting outbreaks and capturing asymptomatic carriers in a timely manner, sewage or wastewater monitoring can be used to trace and track the presence of SARS-CoV-2, and screen entire communities, becoming a valuable indirect epidemiological prediction tool for COVID or other pandemic viruses. Several methods including polymerase chain reaction (PCR), plaque-forming test and laboratory-on-a chip can be used for virus quantification, and can provide an alert if viral particles rise above recommended thresholds[123,124]. The implemented AI technology would help with the integration of collected information and aid in the identification of patterns and anomalies for early detection of COVID, allowing for quicker action and containing the infection before it spreads at an alarming rate. If warning signs occur, the AI-assisted system would suggest that individuals seek molecular testing immediately for clinical diagnosis. The system would recommend suitable and effective isolation actions such as self-isolation at home with physiological and symptoms monitoring, centralized quarantine, or even partial lockdown to break the transmission chain.

Using the aforementioned wearable technologies, mHealth, and telemedicine combined with AI for data fusion and decision making, it is possible to control the spread of the disease in its earliest phase and obtain immediate medical intervention in case of clinical deterioration. It is also possible to suggest whether people need additional medical examinations (i.e., imaging), decide whether to keep people isolated or quarantined, and maintain frequent and ongoing monitoring of patients who are experiencing COVID or long COVID. Moreover, a published recommendation advocates for the utilization of wearable-based mHealth technologies in the closed-loop management of acute cardiovascular disease (CVD) patients during the COVID-19 pandemic[125]. Another study proposed a wearable telehealth system for monitoring COVID-19 and chronic diseases[114]. Given the resemblance in devices and technologies employed, with minor adaptations, the proposed responding system shows potential for extending its applications beyond COVID-19, specifically in addressing cardiovascular diseases in non-pandemic situations. The system can seamlessly transition to effectively respond to pandemic situations during outbreaks, and may help to optimize the efficiency and effectiveness of managing urgent patient care and reducing infection risk.

Furthermore, the widespread adoption of fluid biomarker testing, including PCR, has become standard practice to ensure safe transit, such as airline travel, especially during the peak periods of a pandemic. However, a significant drawback of this approach is the time required to receive test results. This delay can potentially yield incorrect negative results if an individual becomes infected during the interim period between testing and result delivery, consequently enabling viral transmission. An additional promising application of the proposed system is its integration with digital passports. It can help relevant sectors to validate passengers’ health documents and use their real-time electronic health data in a safe and secure way to facilitate real-time infection monitoring. A noteworthy milestone occurred on 1 July 2023, when WHO took up the European Union (EU) system of digital COVID-19 certification to establish a global system that will help protect citizens across the world from on-going and future health threats, including pandemics[126,127]. Overall, the integration of these digital approaches is a transformative development that offers a wide range of benefits, including real-time infection monitoring, rapid contact tracing, streamlined travel processes, safe free movement, enhanced public health surveillance, and optimized resource allocation. The adoption of such digital approaches necessitates careful consideration of legal and validation steps, which involves close collaboration among governments, regulatory bodies, healthcare providers, technology developers, and researchers[128,129].

CHALLENGES AND PERSPECTIVES ON PREDICTION OF FUTURE PANDEMICS

This paper provides an overview of wearables and their potential applications in combatting COVID-19, including early prediction, physiological monitoring, molecular detection, and long COVID patient care. We suggest a wearable-based precise and rapid response system and highlight the capabilities of wearable technology with contact tracing and AI support. Despite the immense potential of wearables, there are numerous obstacles that prevent their widespread usage. In this section, key challenges with the use of wearables are identified, and promising directions are suggested for a better population and patient health response to the COVID-19 pandemic and to possible future pandemic emergencies.

(1) To the best of our knowledge, there are no wearables available for rapid molecular detection for the early detection of COVID-19. Developing highly sensitive molecular detection wearables capable of detecting the virus in a low load before the patients become contagious could effectively cut the transmission chain to avoid disease spread.

(2) Multiple sensors for obtaining several related signals at the same time can result in discomfort, higher costs, and compliance issues. Innovations in multimodal sensor design to continuously monitor large-scale data streams from multiple sources may provide more detailed information than any single sensor.

(3) With advanced material and fabrication technology, flexible and stretchable sensing-based wearable devices for COVID have been extensively investigated. Even if it could be worn comfortably for unobtrusive monitoring, there still exist issues such as the trade-off between thin-film design and power supply, sliding during motion, irritability, and long-term adherence.

(4) Combining biochemical sensors to gather molecular information and physical sensors to monitor physiological signals is a potential direction for the next generation of wearables. Integrated sensors on wearables may be employed as a substitute method for predicting COVID progression, early detection, monitoring health status, and diagnosis of the disease and its long COVID impacts. Though the sensitivity and selectivity are highlighted, there are still issues in accuracy and speed.

(5) It is worth exploring wearable technologies utilizing 2D images or high dimension data, allowing for continuous and real-time image assessment, such as cardiac function assessment[91], which could be beneficial for patients experiencing severe symptoms or long COVID effects. Further work is required to increase spatial resolution, create novel reconstruction algorithms, and miniaturize the entire system, particularly the data processing and power supply backend.

(6) Other technical and usage challenges are inevitable in the development of wearables, including real-time data processing, lack of wide acceptance by clinical professionals[130], power consumption and cost-effectiveness, and user comfort (especially for long-term monitoring), all of which continue to limit the effective adoption and uptake of wearable technology.

(7) Compared with manual contact tracing, developing wearable-based mHealth contact tracing with symptom tracing could not only identify individuals who were in contact with a COVID-positive patient, but also identify if contacts were made with pre-symptomatic or asymptomatic patients. However, accuracy, response time, and privacy issues are areas that need further addressing with these approaches. Additionally, a contact-tracing application with the potential to be widely adopted by a free market must consider a fair trade-off between several design constraints, including trust constraints, reliable range constraints, and low/ultra-low energy consumption constraints[131].

(8) It is challenging to develop effective methodologies to integrate and evaluate complex, multimodal healthcare data such as wearable sensing, biomarkers and imaging information with GPT technologies to enable tele-consultations, tele-monitoring, tele-diagnosis, and even tele-intervention to receive specialized COVID patient care from hospitals to homes/individuals.

(9) The benefits for general populations include professional medical advice, AI-assisted living, and homecare provided by virtual doctors who enable tele-consultations, tele-monitoring, tele-diagnosis, and even tele-intervention. Furthermore, it might arm caregivers with powerful tools for a more thorough evaluation, a precise and prompt diagnosis, and specialized COVID patient care.

(10) It is worth conducting large-scale feasibility and validation studies on the use of wearables to provide similar information as those from clinical tests such as pulmonary function tests[114]. This would provide for faster and more widespread screening and early diagnosis of COVID.

(11) It is necessary to develop standardized protocols for reporting and sharing disease-related multi-source data across healthcare facilities. Standardizing electronic health records (EHRs) and telemedicine platforms would allow for them to be leveraged to facilitate swift and secure information exchange while ensuring privacy protection and data security.

(12) It is important to provide a secure healthcare and data sharing environment when taking management strategies such as digital passports. Ethical considerations and regulatory and privacy-preservation constraints must be considered. Currently, sovereign liability laws are not at all AI-ready. Therefore, the liability system needs to be adjusted or patients, customers, and AI developers will all be harmed by poor liability policies.

In summary, wearables offer tremendous potential to provide quick reactions to outbreaks and better care for the public by combining mHealth and AI technology. However, there are still limitations and challenges that need to be addressed for clinical-grade reliability for successful implementation in pandemic management scenarios. Primary concerns revolve around data privacy, data security, and data ownership, as wearable devices collect sensitive physiological information that needs to be handled with utmost care to prevent unauthorized access or breaches[12]. Balancing individual rights to privacy with public health will be particularly important during specific situations. The reliability of AI algorithms in interpreting data accurately and providing meaningful insights is contingent upon the quality and diversity of the training data available. It is important to note that the clinical design and implementation of these wearables were conducted in resource-rich settings, which can, in turn, create intrinsic biases in the dataset[132]. Moreover, bias in the training data can lead to skewed predictions and hinder the algorithm’s generalizability. Regarding hardware development, the use of healthcare wearables remains in relatively early stages of development. Further improvements are still required in sensor performance, accuracy, user comfort, and other related aspects. Additionally, factors such as user compliance, device calibration, and potential technical glitches could affect the reliability and accuracy of the collected data. These challenges highlight the necessity for adopting a holistic approach that encompasses regulatory considerations, technological advancements, and user-oriented design principles for effective implementation. If the suggested system and associated technologies could be fully constructed and distributed, it would be possible to achieve prediction and early detection of COVID, improve clinical diagnosis, and provide patient-centered long COVID care. Additionally, these approaches would offer prompt medical assistance, teleconsultation, telemedicine, user-oriented healthcare, etc., thereby improving pandemic response capabilities and lightening the burden on healthcare professionals and institutions. Multidisciplinary collaboration between scientists, healthcare professionals, engineers, and policymakers is essential to design, verify, and upgrade the system for handling future pandemics. The proposed system could broaden utilizations in various diseases beyond COVID-19, possessing the capacity to revolutionize the existing healthcare framework and generate far-reaching implications, elevating it to unprecedented levels.
