Analysis of HIV/AIDS Sentinel Surveillance Results among Injection Drug Users,Female Sex Workers and Pregnant Women in Ningming County

Objective This work was to understand AIDS-related knowledge level, behavior characteristics and HIV infection among the three populations of injection drug users, female sex workers and pregnant women in the China-Vietnam cross-border, Ningming County, providing scientific proof to HIV/AIDS prevention and treatment in the future. Methods Based on the requirements of national sentinel surveillance implementation plans, questionnaire survey and tests of serum HIV, syphilis and hepatitis C virus were carried out among the three populations. Results Among 944 injection drug users during 2011-2013, the rates of infection with HIV, syphilis and HCV were respectively 10.49%, 17.27% and 71.4%, respectively. 88.03% them were aware of AIDS; 47.67% of them once shared the needles and 42.58% of them did not use condoms in the last commercial sex behavior. Among 1202 female sex workers, the rates of infection with HIV, syphilis and HCV were respectively 1.58%, 9.48% and 2.7%. 87.02% of them did not use condoms in the last sex behavior with their fixed partners. During the latest commercial sex, the rate of condom use among Chinese female sex workers reached 95.49%, higher than that (78.26%) of Vietnamese female sex workers, showing statistical significant difference. In addition, AIDS awareness among Chinese female sex workers reached 98.56%, higher than that (86.57%) of Vietnamese female sex workers, also showing statistical significant difference. Among 1200 pregnant women, the rates of infection with HIV, syphilis and HCV were 0.5%, 0.83% and 0.25%, respectively. 75.83% of them were aware of AIDS. Conclusion In Ningming County, injection drug users and female sex workers usually experienced high-risk behaviors, having a higher rate of infection with HIV/STD. As a result, Ningming should strengthen behavioral intervention to these groups, in particular Vietnamese female sex workers. Meanwhile, effort should focus on preventing mother-to-child transmission (PMTCT) so as to curb the spread of AIDS/HIV in the county.
