Retrospective survey of rabies in Paraíba State, Brazil, from 2004 to 2011
The aim of this work was to perform a retrospective study of rabies in herbivores in the state of Paraíba, Brazil, in order to evaluate epidemiological aspects of the disease from 2004 to 2011. Data on notification of rabies cases included in the Continental Epidemiological Surveillance System (SIVCONT) were used. During the study period samples from 17,454 animals from Brazil were sent to rabies diagnosis, from which 43 (0.25%) samples from the state of Paraiba, and all of them were positive for rabies. The frequency of rabies outbreaks by county ranged from 2.3% to 11.6%. The distribution of cases ranged according to species affected, with predominance in cattle (93%), followed by horses (4.7%) and one bat (2.3%) (p < 0.001). It was observed a predominance of positive cases when the notification was made by owners (53.5%), followed by others (39.5%) and surveillance (7%) (p = 0.001). Related to occurrence of outbreaks by month in all years of the study period, the frequencies ranged from 4.7% in August to 14% in April. It was found predominance of outbreaks in 2010 (41.9%), with significant differences among years (p < 0.001). In conclusion, it is suggested the adoption of strategic measures for the control of rabies and continuous surveillance of nervous diseases in herbivores in the state of Paraíba.
