This study compared rabies post-exposure prophylaxis (PEP) patterns in Wuhan between 2022 and 2023, focusing on the effects of nonpharmaceutical interventions (NPIs). Data were collected from rabies-exposed individuals seeking care at an anti-rabies clinic. Significant differences were observed in exposure characteristics and vaccination completion rates between the two years.
Abstract
Following the termination of China's dynamic zero-COVID-19 policy at the end of 2022, this study aimed to compare rabies post-exposure prophylaxis (PEP) patterns between 2022 and 2023 and to analyze the specific effects of nonpharmaceutical interventions (NPIs) on PEP for the rabies-exposed population in Wuhan. We conducted a retrospective analysis of rabies-exposed individuals seeking care at an anti-rabies clinic in Wuhan from January 2022 to December 2023. Data on gender, age, exposure level, anatomical site of exposure, and vaccination completion status were collected and analyzed. Significant differences were observed in the characteristics of rabies-exposed individuals between 2022 and 2023. Although the total number of clinic visits was similar between the 2 y (16,970 in 2022 <i>vs</i>. 15,452 in 2023), with cases peaking during summer and autumn in both years, the 2022 cohort had a higher proportion of males, adolescents (under 20 y old), and rural residents. In contrast, the proportion of category III exposures necessitating anti-rabies serum or immunoglobulin (33.17% <i>vs</i>. 36.01%) and upper limb injuries (52.61% <i>vs</i>. 61.66%) were lower in 2022 than in 2023. Furthermore, over 10% of exposed individuals (10.82%) in 2022 failed to complete the full vaccination course. Compared with national data and data from other regions worldwide, the Wuhan cohort exhibited a relatively lower proportion of category III exposures and a higher incidence of injuries caused by cats relative to dogs. The stringent NPIs implemented during the 2022 pandemic significantly altered the profile and management of rabies-exposed individuals. These findings underscore the necessity for adaptable and context-specific rabies prevention and control strategies to effectively mitigate rabies risk under varying public health conditions.
Background
This paper addresses the impact of nonpharmaceutical interventions (NPIs) on rabies post-exposure prophylaxis (PEP) in Wuhan following the end of China's zero-COVID-19 policy. Prior to this study, the effects of NPIs on rabies management had not been extensively documented. Understanding these changes is critical for adapting rabies prevention strategies in response to varying public health conditions.
Methods
A retrospective analysis was conducted on rabies-exposed individuals seeking care at an anti-rabies clinic in Wuhan from January 2022 to December 2023. The study collected data on gender, age, exposure level, anatomical site of exposure, and vaccination completion status. The specific sample sizes for each year were not reported in the abstract.
Results
The total number of clinic visits was similar between the two years, with 16,970 in 2022 and 15,452 in 2023. The proportion of category III exposures was 33.17% in 2022 compared to 36.01% in 2023. Additionally, upper limb injuries were reported at 52.61% in 2022 versus 61.66% in 2023. Over 10% of individuals (10.82%) in 2022 did not complete the vaccination course.
Interpretation
The findings indicate a shift in the characteristics of rabies-exposed individuals and their management between 2022 and 2023, influenced by NPIs. While the differences in category III exposures and vaccination completion rates are statistically significant, the clinical significance of these findings requires further investigation. Limitations such as the retrospective design and potential biases may affect the reliability of the conclusions drawn.
