Objective To investigate the epidemiological features and the loss to follow-up status among volunteer blood donors who were infected by the human immunodeficiency virus( HIV) in Wuxi,and to formulate measures to reduce the risk of blood transmitted diseases according to these features. Methods The blood samples of volunteer blood donors were tested by two ELISA kits from different manufacturers. Positive samples were confirmed by Western Blot at the Center for Disease Control and Prevention in Wuxi. The HIV infection rate and epidemiological data of these confirmed positive donors were analyzed. Results The HIV infection rate of volunteer blood donors was 2. 41 per 10 000( 54 / 224 110) from 2011 to 2015 in Wuxi and increased annually. Among a total of 54 HIV infected blood donors,13( 24. 1%) donors were lost to follow-up and the rate of loss to follow-up increased annually( P = 0. 012). In 2015,the total numbers of donors lost to follow-up were the sum of the past four years. The rate of loss to follow up was higher in married donors( 45%) than in unmarried( 14. 8%)and divorced( 0%) donors( P = 0. 005). Conclusion The rate of HIV infected blood donors who were lost to follow-up was higher in this region and higher in married donors. These donors increased the risk of blood collection and supply because they donate blood with insincere motive. In order to reduce the rate of loss to follow-up and guarantee the safe of clinical blood use,blood donation and supply institutions should strengthen efforts in consultation before blood donation,and provide these donors with guidance for HIV testing in other institutions.
