Risk of human exposure to animal bites in China: a clinic-based cross-sectional study

Abstract

Human exposure to animal bites is the most important public health concern in relation to rabies transmission. This study aims to determine the factors associated with human exposure to animal bites in China. A cross-sectional study of visitors to rabies prevention clinics who were seeking treatment because of exposure to animal bites or scratches was conducted in Wuhan, China. Humans exposed to animal bites (n = 1015) were interviewed, and 87% of the bites were attributed to domestic animals. The risk types for animal bites included unprovoked aggression (31.7%), excessive play (27.5%), insufficient preparedness (26.7%), and improper care of animals (14.1%). Children aged 1-15 years (OR = 9.069, 95% CI: 4.572-17.987, P < 0.001) were more likely to be injured because of excessive play. Nonvaccinated people (OR = 2.168, 95% CI: 1.034-4.545, P = 0.040) and people who discontinued the rabies vaccine regimen (OR = 2.600, 95% CI: 1.561-4.331, P < 0.001) were at risk of rabies exposure and were more likely to be injured because of improper care of animals. This study showed that domestic animals were responsible for most animal bites. The associated factors were age, educational attainment, and animal ownership. Community health education with a special attention to schoolchildren and animal owners should be provided.
