In endemic regions, tuberculosis in children constitutes a bigger fraction of total cases as compared to those in low endemic regions, regardless of the implications, this phenomenon has been historically neglected. Pediatric tuberculosis has an insidious onset and quickly develops into disseminated disease and the young are at a special risk for dissemination. Some studies suggest that measures to contain adult tuberculosis are not enough to manage tuberculosis in children, meaning that pediatric tuberculosis needs dedicated attention. Children are harder to diagnose than adults, because collecting samples is difficult, and their bacterial yield is low. In endemic countries, such as Mexico, where contact with Mycobacterium tuberculosis is common, immunological tests are inconsistent, especially in immunocompromised children. With the disruption of Mexican healthcare services by the COVID-19 pandemic, there is an uncertainty of how the situation has evolved, current data about tuberculosis indicates a drop in the national report of cases: 15.4 per 100,000 persons in 2021, compared with pre-COVID 2019 17.7 per 100,000 persons, a small increase in mortality: 1.7 per 100,000 in 2021 compared with 2019 1.6 per 100,000, a drop in treatment success: 80.4% in 2021 compared with 85.4% in 2019, and a decrease in national vaccination rates: an estimate of 86.6% children between 1 and 2 years-old were vaccinated in 2021 compared with 97.3% reported national rate in 2018-2019. There is a need for new research on regions with high tuberculosis incidence, to clarify the current situation of pediatric tuberculosis and improve epidemiological surveillance.
