Background: Meningitis is a brazilian public health problem due to annual outbreaks¹. Meningitis morbimortality rate is still relevant and the epidemiological description contributes to preventive actions¹,². Objectives: Describe the epidemiological profile of meningitis cases reported by region in Brazil between 2015-2020. Design and setting: A retrospective descriptive study of meningitis cases. The data were obtained from Sistema de Informações de Agravos de Notificação (SINAN). Methods: Information on age, sex, race, etiology, serogroup and case evolution were collected. Results: Between 2015-2020, 87,189 cases of meningitis were reported, among which 58.9% were male. The majority of cases occurred in the Southeast (53.8%). The white race stood out in the South and Southeast, and the mixed race in the North, Northeast and Midwest. The 20-29 age group was the most prevalent, with the exception of the Southeast, where the predominance was 1-4-year-olds. Viral meningitis was the most frequent (47.2%), except in the Midwest, where non-primary meningitis (31.1%) was the main agent. Serotype C (57.8%) was the most prevalent across all regions. Hospital discharge was the main evolution (77.5%), especially in South (79.6%) and Southeast (77.5%). However, the highest death rate occurred in the North (14,6%) and Midwest (12.2%). Conclusions: Male and young people are more affected by meningitis. Despite a higher incidence in the Southeast region, the North has a higher proportion of deaths, revealing a public health problem.
