Figure 1. Example of the page that includes newborn screening results in the national vaccination card in Mexico since 2023. Parents of newborns in Mexico receive a national vaccination card that is used to record all immunizations, and basic medical and wellness evaluations from 0 to 9 years of age. Since July 2023, the national vaccination card includes and must have recorded the results of the five different screenings that are performed in newborns: metabolic, hearing, visual, cardiac, and hip dysplasia. Although ENBS is now mandated in Mexico, the number and list of conditions are unspecified and variable depending on the healthcare institution of parents’ affiliation.
