OBJECTIVE: to analyze the prevalence of meningitis in children ranging from 0 and 12 years of age, hospitalized at the Hospital Universitário João de Barros Barreto (Belém - Pa) wthin January, 1995 + and December, 2004. METHODS: This is a transversal study of prevalence based on electronic data collected by the Department of Statistics and Medical Archives belonging to the hospital. The following information has been obtained: number of patient’s medical records, age, sex, etiological agent, origin, duration of hospitalization and type of discharge. RESULTS: The prevalence of meningitis during the period under study was 20,6%, corresponding to 2077 children, with a tendency of reduction throughout the years, mainly after 1999. The predominant group consisted of male children, wthin 3 months and 5 years old, forming 60,2% and 59,7%, respectively. The non-specified bacterial etiology was the most prevalent (46,4%), followed by virus (20,2%), N. meningitidis (15,2%), H. influenzae (9,3%), S. pneumoniae (3,2%), M. tuberculosis (3,1%), fungus (1,8%) and others (0,9%). In the 0 to 2 months age bracket, the prevalent bacteria identified was H. influenzae (8,7%). Within 3 months and 5 years, N. meningitidis (14,8%) and H. influenzae (14,8%) predominated. Within 6 and 12 years, N. meningitidis was the most frequent bacteria (16,4%). The average time of hospitalization was 26 days and the lethal coefficient was 9,29%.
