Objective: To estimate the prevalence rate of HIV infection among paid blood donors and to analyse high risk factors.
Method: All residents between 18 to 60 years old were selected from on county in March 1999.
Results: There were 210 paid blood donors among 730 interviewed subjects. The HIV prevalence rate among paid blood donors was higher (9.1% or 19/210) than that of others (0.6% or 3/520). The HIV prevalence rate was higher in plasma donors (25.9%) than that (2.6%) among 210 blood donors. Donors who donated blood/plasma more than 10 times each year had a higher prevalence rate (13.5%) than those who donated less than 10 times each year (2.8%). Donors who had donated blood but stopped donation before 1995 had a higher prevalence rate (18.3%) than those who started donation after 1996 (1.4%). The results of KAP survey showed that blood donors had a low knowledge about AIDS.
Conclusion: There was a higher prevalence rate of HIV infection among paid blood donors in some regions. It should take measures to prevent further transmission HIV through paid blood donors.
