Distribuição espaço-temporal da raiva bovina em Minas Gerais, 1998 a 2006

Abstract

Epidemiological data of bovine rabies were evaluated after analyzing 6,873 files collected in Minas Gerais state, from 1998 to 2006. Direct Immunofluorescence was performed to diagnosis the disease. The temporal distribution of the disease was analyzed after tables and graphics were made using the software Excel 2003. A mapping diagnosis was built using the applicatory Tabwin 1.4. It was observed an annual decreasing tendency in the number positive diagnosis (Y= -41.133x+544.89). A higher percentage of positive diagnosis for rabies was observed from May to July. There was a variation in the number of counties in which bovine rabies was diagnosed during the studied period and it maintained a decreasing trend (Y= -7.0833x+166.64), with expansion of the disease in direction of "Triângulo Mineiro" counties.
