Rabies control in Brazil from 1980 to 1990

Abstract

The epidemiological situation of rabies in Brazil at the period of 1980 to 1990, when the National Program for Rabies Prevention was implemented on a national scale, and which yielded positive results, is presented. The main controling actions carried out in order to achieve these results are also described. Rabies in Brasil registered a considerable decrease in human and canine cases (78% and 90%, respectively), half way through the series of analyses undertaken for this study. Towards the end of the decade, the disease began to recrudesce, several cases occurring in some parts of the country, mainly in the northeastern region, where 70% of the total number of infections for 1990 was recorded. Moreover, human rabies transmitted by bats experienced a considerable increase, accounting for 15.1% of the total. The Program, which is implemented by State and Municipal authorities. Covers the 350,000 people who are attacked by animals, and vaccinates approximately 9,000,000 animals every annually year. Epidemiological control is considered to be of basic importance, so that indicators for the definition of the areas of risk have been developed.
