Objective Based on the human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS) incidence data of Chishui City from 2005 to 2024, this study aimed to understand the epidemic characteristics and transmission modes, propose targeted intervention measures, and provide a scientific basis for government decision-making. Methods HIV/AIDS case data for Chishui City were collected from the “China Disease Prevention and Control Information System-AIDS Prevention and Control Basic Information System”. Data were organized using ExceL and statistically analyzed using SPSS 25.0. Descriptive analysis was employed. Inter-group comparisons and analysis of incidence trends over the years were performed using the χ2 test and trend χ2 test, respectively, with a statistical significance level set at P<0.05. Results From 2005 to 2024, the overall incidence of HIV/AIDS in Chishui City showed an increasing trend(P<0.05). Case characteristics were as follows: males significantly outnumbered females(2.20∶1), with a statistically significant gender difference(χ2=154.04, P<0.001). Cases were primarily concentrated in the 50 ～ 59 age group. The educational level was predominantly primary school, the main occupation was farmer. The primary mode of transmission was heterosexual contact. Geographically, cases were mainly distributed in the urban area and five eastern townships. Conclusion Chishui City should expand HIV testing coverage for early detection, implement precise health education targeting key populations such as middle-aged and elderly individuals, strengthen behavioral interventions in high-risk venues, and strictly enforce follow-up management of cases.
