To detect recent HIV incidence of injection drug users (IDU) from a surveillance site of IDU in Guangxi and estimate HIV incidence.
787 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.
A 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.
The 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.
检测广西某注射吸毒者（IDU）监测点IDU的近期HIV感染率并估算HIV发病率。
收集广西某IDU监测哨点（2005 - 2007年）的787份样本进行ELISA检测，168份HIV-1呈阳性；随后对168份HIV-1阳性样本采用BED捕获酶免疫测定法（BED-CEIA）检测，17份呈阳性。
共检测787份样本，168份HIV-1阳性，17份BED-CEIA阳性。该IDU监测哨点2005至2007年的患病率分别为23.06%（92/399）、21.90%（46/210）和16.85%（30/178），发病率分别为7.41%（10/135）、6.94%（5/72）和3.12%（2/64）。
广西某IDU监测点IDU的HIV感染发病率近年来似呈缓慢下降趋势，部分可能已感染较长时间。
