Introduction: Viral encephalitis is a condition with high morbidity and mortality rates, and a better understanding of its epidemiology may contribute to the construction of prevention and control strategies. For this reason, this study aimed to draw an epidemiological profile for viral encephalitis in Brazil in 2018 from data on hospitalizations in the Unified Health System (SUS). Methods: Ecological study of spatial analysis. The data studied were hospitalizations for viral encephalitis in SUS in 2018, stratified by federation unit (FU), gender, and age group. The geographical distribution was approached in an exploratory way, whereas gender and age variables were analytically addressed. Results: There were 2075 hospitalizations, with a rate of 0.99/105 inhabitants. The rates for each FU were represented in a colorimetric map, whereas the rates for each sex and age group were exemplified in a univariate comparative table. Discussion: There was a wide numerical variation in hospitalization rates among the FUs, with Pernambuco being the state with the highest incidence (4.13/105 inhabitants) and Paraíba with the lowest (0.29/105 inhabitants). A significant association was found with the risk of hospitalization for viral encephalitis for males and the ages from 1 to 4 years (RR: 3.28) and under one year (RR: 6.02). Conclusion: FU, gender, and age group were important determinants of the hospitalization rate due to viral encephalitis. However, current studies are needed in Brazil and worldwide to better characterize the epidemiology of viral encephalitis.
