Human post exposure anti-rabies prophylactic assistance in the south of Brazil

Abstract

Rabies is a zoonosis caused by Lyssavirus, with progressive development and a high lethality rate. In Brazil, rabies and accidents caused by animals potentially transmitting the disease are mandatory notification injuries. Exposure to rabies infection places a high financial burden on public health systems, especially for the care of people who are exposed and have a high risk of death. We aimed to define the epidemiological profile of human rabies post-exposure assistance in the municipality of Santa Maria, Rio Grande do Sul, Brazil, from 2010 to 2015. Data from Brazil's Notifiable Diseases Information System were obtained and analyzed; these data were acquired by the completion of individual inquiry forms querying human anti-rabies assistance. A total of 55% (1,898/3,453) of anti-rabies assistance cases involved women and 45% (1,555/3,453) men. The highest occurrence (54.5%–1,882/3,453) was in the age group of 20–59 years. Most registered cases (87.5%–3,024/3.453) were caused by dogs, followed by cats (10.9%–378/3,453). The lower limb (22.1%–617/2,790) was the area of the body with the highest number of canine bites. We observed incorrect indications for the treatment. We suggest further training for health professionals involved in rabies post-exposure prophylaxis care, and dissemination of information aimed at educating users about the importance of animal-related injuries.
