RESUMO

In the State of São Paulo, the Coordenadoria de Defesa Agropecuária-CDA, an administrative unit directly subordinated to the State Secretary of Agriculture was established in 1998. Subsequently, the frequent outbreaks of paralytic rabies in herbivores in Eastern part of the State, including the region of Vale do Paraiba and the Greater São Paulo, between 1999 and 2001, have led to change the strategies for controlling the disease being conducted up to that time in the State. In 2001, the vaccination of domestic herbivores was declared obligatory in regions under the jurisdiction of Escritórios de Defesa Agropecuária - EDAs located in areas classified as rabies epidemic and endemic, and by the reinforcement of the control measures directed against the Desmodus rotundus vampire bats by means of joint effort of EDAs to capture and control the bats using mist nets and the vampiricides (anticoagulant paste), besides the registration, revision and the use of geographical information systems to locate the bats roosts and shelters in strategic regions, in order to interrupt the progression of the disease through the reduction of the bat population density and the viral circulation. In this study, it was considered the number of rabies in herbivores with laboratorial confirmation and according to the year of occurrence, animal species, and distributed by EDAs and by municipalities, provided by the Pasteur Institute-São Paulo. Data regarding 2001, the percentages of vaccination were grouped without the division into EDAs, due to the absence of data. From 2002, the data were divided into EDAs where vaccination has been declared obligatory, and data discriminated into properties that vaccinated and herbivores vaccinated against rabies. The number of captured vampire bats was provided by the respective EDAs. By analyzing the trends indicated by the properties that vaccinated against rabies and the herbivores vaccinated and the amount of vampire bats captured, it was observed a decrease in rabies cases in 90% or more, and with these results we conclude that for the control of rabies in herbivores, the easures adopted must be focused primarily in vaccinating the target animal species and in a well planned and organized measures of control directed to the main reservoirs, i.e., the Desmodus rotundus bats.
