ObjectiveTo understand the epidemiological characteristics of rabies in Chongqing in 2018 and provide evidence for the control and prevention of rabies.
MethodsThe incidence data of rabies in Chongqing in 2018 were collected from national infectious disease reporting information management system, the data of case exposure and prophylaxis from the rabies investigation database of Chongqing, and the data of dogs biting events from national public health emergency management information system. Descriptive epidemiological methods were applied to analyze the epidemiological characteristics of rabies cases.
ResultsA total of 18 rabies cases were reported in Chongqing in 2018, with a reported incidence of 0.06/100 000. The majority of the cases were people over 60 years old (61.11%) and farmers (88.89%). All the cases were from rural areas of suburb counties and districts. Two geographic epidemic clusters were identified in six districts and counties in western Chongqing and three districts and counties in northeastern Chongqing. Up to 94.44% of rabies cases were victims of dog bites or scratch, and 61.11% of the cases exposed to stray dogs. None of these cases received standard prophylaxis after rabies exposure. Up to 88.89% of the dog biting events occurred in rural areas and 18.52% of the dog biting events affected more than 10 people.
ConclusionThe incidence of rabies in Chongqing continued to decline in 2018 and the areas affected by the epidemic further decreased. The disease mainly occurred in rural areas of several districts and counties in western and northeastern Chongqing. The most rabies affected population was the people over 60 years in rural areas. The rabies cases were mainly caused by dog biting, and the proportion caused by stray dog biting increased further, and all the cases received no substandard post-exposure prophylaxis.
