Abstract

OBJECTIVETo detect recent HIV incidence of injection drug users (IDU) from a surveillance site of IDU in Guangxi and estimate HIV incidence.

METHODS787 Samples from a IDU surveillance sentinel site in Guangxi (2005 - 2007) were collected for ELISA and 168 were HIV-1 positive; then 168 HIV-1 positive samples were detected by BED capture enzyme immunoassay (BED-CEIA) and 17 were positive.

RESULTSA total of 787 samples were tested and 168 were HIV-1 positive and 17 were BED-CEIA positive. The prevalence rates of the IDU surveillance sentinel site were 23.06% (92/399), 21.90% (46/210) and 16.85% (30/178), and the incidence rates were 7.41% (10/135), 6.94% (5/72) and 3.12% (2/64) respectively from 2005 to 2007.

CONCLUSIONThe incidence rate of HIV infections of IDU from a surveillance site of IDU in Guangxi appeared to decline slowly in recent years, and some might have been infected for long time.
