Abstract：Objective To understand the acquired immunodeficiency syndrome (AIDS) epidemic trend and current situation of five key groups in Jingzhou from 2016 to 2020, and to provide clues for epidemic analysis and prevention. Methods According to the Requirements of the National AIDS Sentinel Monitoring Implementation Plan, a total of 14 000 people from five categories of drug users (DUS), men who had sex with men (MSM), female sex workers (FSW), male patients in clinics sexually transmitted disease (STD) and pregnant women (PRG) at the AIDS surveillance sites were collected in Jingzhou area from 2016 to 2020. While social demography, behavior and serological information of HIV, Syphilis, and hepatitis C virus (HCV) were performed. Results Most of DUS were married men, and the HIV positive detection rate had been well controlled during 2018 to 2020, but its hepatitis C infection rate was the highest. There was a statistically significant difference in the positive detection rates of HIV and syphilis in each year (P ＜ 0.05). During the monitoring period from 2016 to 2020, the proportion of injecting drug users in the last month was 18% to 26%. MSM was dominated by young people with higher education, and its HIV infection rate was the highest among the population, with an upward trend during 2018 to 2020. There was a statistically significant difference in the positive detection rate of HCV in each year (P ＜ 0.05). The proportion of anal sex with the same sex in the last six months reached 100% every year from 2016 to 2019. FSW was a married person with a low education level, the HIV infection rate was low, the syphilis detection rate was maintained at more than 2% every year, and the proportion of condom use in the last commercial sex during 2016 to 2020 had increased year by year, maintaining at 92.00% to 99.75%. STD covered all age groups. Due to the low proportion of prostitution in the past three months, the infection rates of HIV, syphilis and HCV were low. There was a statistically significant difference in the positive detection rate of syphilis in each year (P ＜ 0.05). The positive detection rate of HIV, syphilis, and HCV in PRG was 0% during the monitoring period. There were statistical differences in age, education level, marital status, and positive detection rate of HIV, syphilis, and HCV among different groups (P ＜ 0.05). The behavioral characteristics of each year were compared, and the differences were statistically significant (P ＜ 0.05). Conclusion From 2016 to 2020, the HIV infection rate of MSM in Jingzhou is the highest and showed an upward trend. Syphilis is mainly transmitted in FSW, and DUS have the highest detection rate of HCV compared with other populations. The wide spread of HIV in MSM is related to its younger trend and high frequency of same-sex anal sex. It is necessary to strengthen the publicity and education of AIDS and its prevention and control knowledge among college students, and implement preventive intervention to curb the spread of AIDS.
