Regarding the age group, it was observed that during the study period, the highest prevalence occurred in individuals between 20 and 39 years (38.3%). There was a change of serotype from DENV-1 to DENV-2, and dengue was the most prevalent classification (95.2%). Concerning hospitalization rates, there was a limited necessity of admissions (5.7%), as well as few deaths due to the notified disease (3,444).

Conclusions: There was a significant growth in the number of dengue fever cases in Brazil in 2019, which represents a public health problem.
