Spread of HIV in one village in central China with a high prevalence rate of blood-borne AIDS

SummaryObjectivesTo determine the state of HIV infection, its secular trends and influencing factors in a village central China with a high prevalence rate of blood-borne AIDS.MethodsHIV screening in WY village was carried out.ResultsThe rate of paid blood donors in WY village was found to be 36.3% (466/1285). The HIV infection rate was 15.3% (197/1285). Among 197 HIV positive cases, 80 (40.6%) were infected through paid blood donation, four (2.0%) were infected through sexual activity, seven cases (3.6%) were infected through mother-to-child transmission, one case (0.5%) was infected through transfusion, and one (0.5%) was infected through nosocomial infection. In 100 cases (50.8%) the infection route could not be identified, however, based on their history of paid blood donation, their age, and the chance of becoming infected with HIV through paid blood donation, it is likely that most of these 100 cases were infected by paid blood donation. In the final four cases the method of transmission could not be determined. Of the infected women of reproductive age only 1.9% (2/103) had the intention to conceive. In the cases of HIV status conflicting spouses, 51.7% (30/58) did not consistently use condoms.ConclusionsThe main route of HIV transmission was found to have been paid blood donation in the past, and will be by sexual means in the future.
