Epidemic curve of the monthly number of RVGE hospitalizations for each surveillance year in six Latin American countries.

Grey lines represent the epidemic curves in the pre-vaccine period and red lines are for the post-vaccine period. Colors become darker in later years. For example, the darkest grey line represents the epidemic curve for the last year prior to vaccine introduction, while the lightest red line represents the epidemic curve for the first year post-vaccine introduction. Abbreviations: RVGE, rotavirus-associated gastroenteritis; BOL, Bolivia; SLV, El Salvador; GTM, Guatemala; HND, Honduras; PRY, Paraguay; VEN, Venezuela.
