柳州市1987～1998年艾滋病流行病学调查

AIDS Epidemiological Survey during Past Twelve Years (1987-1998) in Liuzhou City

自1987年先后对援外回国人员、嫖娼者及暗娼等1578人,注射过HIV抗体阳性进口人血丙种球蛋白者689人开展HIV感染的流行病学调查,结果抗—HIV全部阴性.1996年对380例吸毒者进行调查,结果也为阴性;但是1997年调查803人,HIV阳性者出现10人,阳性率为1.25%;1998年调查621人,阳性者43人,阳性率为6.92%,两年间阳性率差异非常显著(x^2=31.52,P<0.01).自1996年发现首例传入性艾滋病病例后,目前已发现本地籍HIV感染者161例,除1例原因不详,余均因静脉注射海洛因引起.表明该人群中HIV呈现迅速流行的趋势.

There was no one HIV positive among 2267 persons including return Chinese, prostitues, clients and patients who received injection of immunoglobulin imported since we had launched epidemiological survey for HIV infection among high risk populations of Liuzhou City from 1987. 380 drug users screened twice in 1996 were also HIV negative. However, in 1997, 10 HIV positive persons were detected among 803 drug users, and in 1998, 43 ones were found among 621 drug users; their HIV positive rates were 1.25% and 6.92%, respectively. There was a significance of difference between the two rates (x2 = 31.52, P<0.01). Sine the first AIDS case of Liuzhou found in October 1996, we had found 161 HIV positve cases. Their infective channels are mainly through drug injecting. It showed that the trend of HIV infection would be rapidly epidemic among this population.
