Abstract:
ObjectiveTo understand the epidemiological characteristics and post-exposure prophylaxis of rabies exposure cases in Suqian City of Jiangsu Province from 2021 to 2024, providing a reference for optimizing the allocation of health resources and formulating scientific prevention and control measures. MethodsData on individuals exposed to rabies and treated at Suqian’s rabies post-exposure prophylaxis (PEP) clinics from 2021 to 2024 were collected. Descriptive epidemiological methods were used to analyze patient characteristics, exposure classification, animal species responsible for injuries, wound management, and vaccination status. ResultsBetween 2021 and 2024, the number of outpatient visits for rabies PEP clinics in Suqian City totaled 333 450. The median age and the 25th and 75th percentiles of exposed individuals was 23 (9, 47) years. The highest proportion of exposed individuals was recorded in 2023 (27.09%); the majority were female (52.22%), aged 5‒9 years (17.49%), and in other occupations (37.05%). The rabies exposure rate in Suqian City from 2021 to 2024 was 16.75‰. The overall rabies exposure rate showed an upward trend (χtrend2

=1 994.80, P<0.001). The exposure rate among males was lower than that among females (χ²=890.43, P<0.001). The highest exposure rate was observed in the 5‒9 age group (χ²=67 063.20, P<0.001). The number of individuals seeking medical care for rabies exposure exhibited a weak bimodal distribution, with the primary peak occurring in August and the secondary peak in January. The primary animal responsible for injuries was the cat (53.70%), and the source of these animals was predominantly domestic pets (88.90%). The proportion of exposed individuals bitten by cats showed an upward trend from 2021 to 2024 (χtrend2![]()

=548.44, P<0.001). Grade Ⅲ exposure accounted for the highest proportion (53.53%), and 301 652 cases (90.46%) presented within 24 hours of exposure. The coverage rate of rabies vaccine was 98.18% (13 625/13 877) for those with Grade Ⅰ exposure and 99.95% (319 413/319 573) for those with Grade Ⅱ and Ⅲ exposures; 64 042 individuals received rabies immunoglobulin or anti-rabies serum; 8 360 exposed individuals received tetanus vaccine, with the usage rate of tetanus vaccine among exposed individuals was only 2.51%, though the rate was on the rise (χtrend2![]()

=618.26, P<0.001). ConclusionBetween 2021 and 2024, the overall incidence of rabies exposure in Suqian City showed an upward trend, with a higher incidence among women than men. The incidence was particularly high among children and adolescents aged 14 and under, with the majority of injuries caused by cats; most injuries were inflicted by domestic animals. The overall uptake of tetanus vaccines showed an upward trend. Suqian City should step up health education on rabies exposure during January and August each year, with a particular focus on raising awareness of rabies exposure prevention among people aged 14 and under and women. It should also strengthen the management of domestic animals and ensure that they receive regular rabies vaccinations, particularly for pet cats. Preventive measures against tetanus should be strengthened for individuals exposed to rabies. Medical staff at rabies PEP clinics should receive enhanced training on the management of rabies exposures and the completion of information system reports to ensure the standardized operation of these clinics.
