For this, was conducted a retrospective study using epidemiological records received by the Central Laboratory (LACEN) of MG in the period 1995-2002. Cases were suspected patients after clinical and epidemiological assessment for BSF and seropositive for Rickettsia ricketsii (IFAT 1:64) in at least one serum sample. As negative suspects were those that have no seroconversion in two consecutive samples to BSF. After adjustment of multiple logistic regression analysis, only the occurrence of rash and seizures were associated with symptoms FMB. Using analysis of main components symptoms that characterized the cases were: rash, convulsions and coma. Moreover cases have a high relation with hospitalization and lack of similar cases. The FMB in Minas Gerais is a serious disease and need early diagnosis.
