The spatial-temporal distribution of newly reported HIV-infected patients and factors associated with recent HIV infection in Taizhou of Zhejiang Province from 2019 to 2022
Objective This study aims to analyze the epidemiological characteristics of newly reported human immunodeficiency virus(HIV)cases and the influencing factors of recent infection in Taizhou City,Zhejiang Province.Methods HIV-1 limiting-antigen avidity enzyme immunoassay(LAg-Avidity EIA)was performed to detect recent infection within new HIV diagnoses reported between 2019 and 2022 in Taizhou City.Multivariate logistic regression models were employed for multifactorial analysis of factors influencing the proportion of recent infection.The spatial analysis was conducted with arc geographic information system(ArcGIS)10.7 software.Results In total,1 785 eligible subjects were enrolled for further study,with 313 cases(17.5％)classified as HIV recent infections.The proportion of recent infections in 2019-2022 was 10.6％,15.9％,23.9％and 20.2％,respectively.The high-risk population for recent infection includes individuals aged 18-＜30 years old,illiterate,homosexual transmission and voluntary testing and counseling.HIV recent infections were primarily distributed in Linhai,Jiaojiang,Luqiao and Wenling.Conclusions The proportion of HIV recent infection in Taizhou City was relatively high and showed an increasing trend from 2019 to 2022.The recent infection cases are predominantly male,with uneven distribution across regions.It is important to enhance targeted education in high-risk population,focusing on areas with dense cases,and strengthen the detection and discovery of individuals aged 40 and above.
