[Comprehensive evaluation on the potential risk for HIV infection in 12 villages with a history of former paid blood donation].

OBJECTIVE:To learn the potential risk for human immunodeficiency virus (HIV) infection in 12 villages with a history of former paid blood donation, and to provide different measures for HIV/AIDS prevention and control. METHODS:Seven indexes were selected, including HIV sero-prevalence rates, hepatitis C virus (HCV) sero-prevalence rates, HIV/AIDS KAB (knowledge, attitude and belief), proportion of paid blood/plasma donation, risks on related behavioral information on sex and HIV/AIDS infections. Rank Sum Ratio (RSR) was performed to synthetically evaluate the potential risk of HIV infection in those 12 selected villages. RESULTS:According to the results of evaluation by 18 experts, weight coefficient of HIV sero-prevalence rate was the highest (0.28), and HIV/AIDS KAB the lowest (0.09) among the seven indexes. The results of comprehensive evaluation with RSR showed that the villages coded 01 and 02 belonged to higher level of potential risk of HIV infection, villages 09, 12, 05, 10 and 03 were at medium level while villages 04, 06, 08, 07 and 11 were at low level. CONCLUSION:The level of potential risk for HIV infection was different in 12 villages with a history of former paid blood donation. Different measures of HIV/AIDS prevision and control should be performed according to the potential risk level for HIV infection of the 12 villages.
