This paper describes a cohort of people living in Victoria, Australia, diagnosed with incident HIV infection and identified through routine HIV surveillance. All HIV diagnoses notified to the Victorian HIV Registry between January 1997 and September 1998 were included. Infections were classified as incident if there was a prior negative test and/or seroconversion illness within 12 months of the first positive HIV test. During the study period there were 277 notifications received of which 70 (25%) were incident infections (seroconversions). People with incident infection were aged 36 years (+/- 10), from an Anglo background (76%) and living in Melbourne (91%). Seroconverters were more likely to have acquired their infection in Victoria (76%), through male-to-male sexual contact (86%), and from casual or anonymous partners (67%). Cohorts of individuals with incident HIV infection provide a valuable resource for understanding the dynamics of HIV acquisition and natural history of the infection.
本文描述了一群居住在澳大利亚维多利亚州的人，他们被诊断出感染了新发艾滋病毒，并通过常规艾滋病毒监测得以确认。纳入了1997年1月至1998年9月期间向维多利亚州艾滋病毒登记处报告的所有艾滋病毒诊断病例。如果在首次艾滋病毒检测呈阳性前12个月内有先前的阴性检测结果和/或血清转化疾病，则感染被分类为新发感染。在研究期间，共收到277例报告，其中70例（25%）为新发感染（血清转化）。新发感染人群的年龄为36岁（±10岁），具有盎格鲁背景（76%），居住在墨尔本（91%）。血清转化者更有可能在维多利亚州感染（76%），通过男男性接触感染（86%），以及通过偶然或匿名性伴感染（67%）。新发艾滋病毒感染人群队列是了解艾滋病毒感染动态和感染自然史的宝贵资源。
