Epidemiological profile of Haemophilus influenzae b meningitis in Regional Health Board of Piracicaba - São Paulo - Brazil

Abstract

The objective of the present study was to characterize the population affected by Hib meningitis from 1992 to 2001, in the Regional Health Board of Piracicaba (São Paulo-Brazil) in terms of variables regarding demographics and the health-disease process. Data were collected from disease notification reports, and arranged using the SINAN Data Program . It was observed there was a peak in the incidence of meningitis in 1994 and a peak of deaths in 1999, before the vaccine had been introduced. The most affected group were male children under the age of 5 years, which is in agreement with literature. Most patients received care at public hospitals in the municipalities of Piracicaba and Limeira, which are references for the community of the entire region, which puts into effect one of the axes of the Health System of Brazil (SUS): regionalization. The introduction of the vaccine reduced incidence in about 73%, which corroborates its importance and shows that is necessary to encourage adherence to vaccination.
