Epidemiologic study of HIV infection among voluntary blood donors in Zhejiang province from 2008 to 2010 / 中华临床感染病杂志

ABSTRACT

Objective To investigate the epidemiologic features of HIV infections in voluntary blood donors in Zhejiang province.Methods A retrospective study was conducted in 206 cases of HIV-positive blood donors who were found from 2008 to 2010 by blood screening in Zhejiang Province,and the demographic data of those HIV carriers were analyzed using SPSS 16.0 software.Results The HIV-positive rates of voluntary blood donors in 2008,2009 and 2010 were 0.09‰(49/552 585 ),0.11‰( 64/601 639)and 0.15‰(93/600 893),respectively.There were five regions in Zhejiang province where HIV-positive rates exceeded 0.10‰,and the highest one was 0.21‰ in Wenzhou.HIV infection rate of male blood donors was 0.19‰,which was higher than that of female donors (0.02‰,x2 =96.21,P ＜ 0.01 ) ; donors with ages of ＞25-35 had the highest infection rate (0.19‰) among all age groups (x2 =41.94,P ＜0.01 ) ; blood donors with education of junior high school or lower had higher infection rate (0.21‰) than those with education of senior high school and undergraduate or above (0.11‰ and 0.02‰,x2 =78.62,P ＜0.01 ).Infection rate of first-time blood donors in 2008 was 0.12‰,higher than that of repeated donors (0.05‰,x2 =7.26,P＜0.01); while in 2009 and 2010,there was no difference between two groups (x2 =0.16 and 1.35,P ＞ 0.05 ).Blood donors who used mobile donation sites had higher infection rate than those using institutional donation (x2 =18.5,22.0 and 16.8 for 2008,2009 and 2010,P ＜0.01 ).Conclusions The risk of HIV infection is gradually increasing among voluntary blood donors in Zhejiang province.To ensure the blood safety,blood agencies should establish pre-donation health consultation for high-risk blood donors such as young men with low education.
