Former illegal blood donation in the past decade has caused HIV outbreaks in some rural areas in China. Other HIV associated virus infections, such as human herpesvirus 8 (HHV8) in such areas are still not well defined. In order to explore HHV8 and HCV seroprevalence and potential risk factors in such areas, a cross-sectional study with 305 HIV positive and 315 HIV negative subjects recruited from a rural county in Shanxi province was conducted, where illegal blood collection was reported. Interview questionnaires and serum testing were carried out with these participants. HCV and HHV8 seroprevalence were found to be higher in HIV positive than negative group (76.4% vs. 2.5%; 15.4% vs. 4.8% respectively), while the difference in HBV seroprevalence was not significant. Co-infection with HCV and HHV8 was also more prevalent in the HIV positive group. HIV status (odds ratio [OR], 2.71; 95% confidence interval [CI], 1.16–6.30) and HBV status (OR, 2.56; 95%CI: 1.14–5.75) were independently associated with HHV8 infection. HIV status (OR, 23.03; 95%CI: 9.95–53.27) and blood/plasma selling history (OR, 14.57; 95%CI: 7.49–28.23) were strongly associated with HCV infection. These findings demonstrate that both HHV8 and HCV infections are prevalent in this community. HIV infection is an important risk factor for both HHV8 and HCV infection. HBV infection is associated with HHV8 infection but not with HCV infection. It is possible that HHV8 and HBV, but not HCV, may have similar mode of transmission in this population.
