What is the epidemiology of Hepatitis A virus infection in Latin American countries and the impact of pediatric vaccination programs?
The transition of Latin American countries to intermediate Hepatitis A endemicity supports the implementation of national childhood immunization programs.
Andani et al. (2020) conducted a systematic review in Hepatitis A virus (HAV) infection. Hepatitis A virus (HAV) infection was evaluated on HAV incidence and prevalence. A systematic review of 59 articles found that most Latin American countries have transitioned to intermediate levels of Hepatitis A endemicity, supporting national childhood immunization.
