LEME, Miriam Vannucchi  e  ZANETTA, Dirce Maria Trevisan. Meningococcal disease in the Sorocaba region, São Paulo State, Brazil, 1999-2008. Cad. Saúde Pública [online]. 2012, vol.28, n.12, pp.2397-2401. ISSN 0102-311X.  https://doi.org/10.1590/S0102-311X2012001400020.

The objective of this study was to describe the occurrence of meningococcal disease reported to the Regional Health Department in Sorocaba, São Paulo State, Brazil, from 1999 to 2008. Annual incidence of the disease was two cases per 100,000 inhabitants, with an increase from 2006 to 2008. Annual incidence rates were highest in the 0 to 4 year age bracket. Case-fatality was 21.8%, higher in the 0 to 4 year age bracket (26.4%), which also showed the highest incidence of the disease, and in the over 30-year age bracket (28%). Diagnosis was confirmed by laboratory test in 71% of cases (culture in 45.3%) and by clinical and epidemiological criteria in 22%. Serological groups were B in 45.7%, C in 47.3%, W135 in 3.7%, and Y in 1.5% of the identified cases, with a predominance of B from 1999 to 2003 and C from 2004 to 2008. The most frequent phenotypes were B:4,7:P1.19,15 and C:23:P1.14-6. The results emphasize the need for regional surveillance of trends in the disease for early detection of outbreaks and monitoring circulating strains.
