| Abstract: |
| 1993年3月对已建立一年的吸毒者定群研究现场——云南省德宏州瑞丽市、陇川县及潞西县再次进行调查。本次调查755例吸毒者及102例配偶。从1992年进入定群研究HIV阴性的89例静脉吸毒者中,1993年又采到血样有54例,其中9例血清转阳。瑞丽市、陇川县及潞西县1992年和1993年静注者血清阳转率(/百观察人年)分别为43.2%及40.0%,12.2%及12.2%,0%及0%。1993年新进入定群研究的116例静注者中,采集到血样的有104例,发现HIV阳性38例。上述三市县1992年及1993年入定群研究的静注者的HIV感染率分别为81.8%及85.7%,44.6%及40.0%,5.1%及0%。可以看出血清阳转率的高低与HIV感染率高低相吻合。HIV阳性者的配偶1990、1992及1993年的HIV感染率分别为3.1%、9.8%和7.4%,有上升趋势。潞西县HIV阳性者少,静脉注射出现时间晚,但近年来静脉吸毒者比例上升快,值得注意。 |

| In 1993, a second survey was conducted in Ruili City and other two counties, where a cohort study field was established last year. Seven hundred and fifty five drug users and one hundred and two spouses of HIV infected IDUs were interviwed. Nine samples among 54 from 89 IDUs in cohort were tested as seroconversion. The seroconversion rate (incidence rate) in IDUs (per hundred person years) in Ruili, Longchuan, and Luxi as well were 40.0, 12.2 and 0, respectively in 1993, comparing to 43.2, 12.2 and 0 in 1992. Thirty eight were tested as positive among 108 samples from 116 newly recruited IDUs. The seroprevalence rates in this three counties were 85.7%, 40.0% and 0 in 1993, comparing to 81.8%, 44.6% and 5.1% in 1992. A coordination of the level between seroconversion and seroprevalence was observed. A increasing trend of seroprevalence among the spouses of HIV positive IDUs was found, the seroprevalence rate were 3.1% in 1990, 9.8% in 1992 and 7.4% in 1993. More attention should be paid to Luxi where the ratio of intravenous drug using increased rapidly, although fewer positives and later starting of drug using was found in this county.
