Year: 2026

Type: article

Abstract: (1) Background: Human rabies continues to be a significant public health challenge and imposes a heavy disease burden. The epidemiological characteristics and post-exposure prophylaxis (PEP) of human rabies in Chongqing were analyzed to provide a scientific basis for its prevention and control in Chongqing. (2) Methods: Data and case investigation forms of the human rabies epidemic in Chongqing from 2016 to 2024 were collected and analyzed using descriptive epidemiological methods. (3) Results: From 2016 to 2024, 84 human rabies cases were reported in Chongqing, with an average annual incidence rate of 0.03 per 100,000 population. Among the cases, 72.6% were aged 45 and above. Farmers constituted the primary infected group (73.8%). Analysis of exposure patterns and PEP revealed that 92.4% of cases involved dog transmission, with domestic dogs responsible for 65.2% and stray dogs for 31.8%. After exposure, 51.5% received no treatment, while only 6 individuals were vaccinated against rabies. (4) Conclusions: Although rabies incidence in Chongqing is low, dogs remain the primary source, and post-exposure vaccination is often delayed. Strengthening health education and dog immunization is crucial for supporting the global "Zero by 30" target.
