To describe the epidemiology of HIV infection acquired in Africa and among African communities in the United Kingdom.
Descriptive analysis using national HIV and AIDS surveillance data, routine voluntary confidential HIV reporting and unlinked anonymous seroprevalence surveys in the United Kingdom to the end of December 2001.
Of all reported HIV infections diagnosed in the United Kingdom by the end of 2001, 21% (9993 of 48,226) were probably acquired in Africa and 90% of these infections were heterosexually acquired. Numbers of diagnoses of HIV infection acquired in Africa have been increasing rapidly, with rises in infections from southeastern and southern Africa predominating recently. Among those living with diagnosed HIV infection in 2000, 23% (4883 of 21,291) were described as black African, 81% of whom lived in London. The proportion living in London has declined over successive prevalence surveys.
Infections acquired in Africa and among Africans are making an increasing contribution to HIV infection in the United Kingdom. Migration, diagnosis of long-standing infection and incident cases are all potential influences, but they are difficult to measure. Improvement in early diagnosis of HIV continues to be an important component of intervention to prevent onward vertical and sexual transmission and to promote access to treatment and care.
描述在非洲以及英国的非洲裔社区感染艾滋病毒的流行病学情况。
利用英国截至2001年12月底的全国艾滋病毒和艾滋病监测数据、常规自愿保密艾滋病毒报告以及非关联匿名血清流行率调查进行描述性分析。
到2001年底在英国诊断出的所有报告艾滋病毒感染病例中，21%（48226例中的9993例）可能是在非洲感染的，其中90%的感染是通过异性传播获得的。在非洲感染艾滋病毒的诊断病例数一直在迅速增加，最近东南部和南部非洲的感染病例增加尤为明显。在2000年诊断出感染艾滋病毒的人群中，23%（21291例中的4883例）被描述为非洲黑人，其中81%居住在伦敦。在连续的患病率调查中，居住在伦敦的比例有所下降。
在非洲以及非洲裔人群中感染艾滋病毒的情况对英国艾滋病毒感染的影响日益增大。移民、长期感染的诊断以及新发病例都是潜在影响因素，但难以衡量。改善艾滋病毒的早期诊断仍然是预防垂直传播和性传播以及促进获得治疗和护理干预措施的重要组成部分。
