Through December 1984, 9932 cases of the acquired immunodeficiency syndrome have been reported, mainly from North and South America and Europe; 85% of these cases occurred in the United States. Haiti and the United States have the highest incidence rates, 59 and 36 per million population, respectively. Rates in the United States range from 0.3 (beginning of 1981) to 10.4 (end of 1984). Brazil, Canada, Denmark, Switzerland, France, West Germany, the United Kingdom, and the Netherlands show a slower increase. Homosexual men and intravenous drug users are still the main risk groups in the United States and Europe. The disease is prevalent in heterosexual Haitians and Africans whether they live in their own countries or abroad. Cases of the syndrome have been identified in Zaire, Rwanda, Zambia, and Uganda, but its full extent is not yet known. Consistent with the general history of epidemics, the appearance of geographically separated sites of incidence of the syndrome could be linked to population migrations; however no evidence has been found to identify an index location.
截至1984年12月，已报告9932例获得性免疫缺陷综合征病例，主要来自北美洲、南美洲和欧洲；其中85%的病例发生在美国。海地和美国的发病率最高，分别为每百万人口59例和36例。美国的发病率从1981年初的0.3上升到1984年底的10.4。巴西、加拿大、丹麦、瑞士、法国、西德、英国和荷兰的发病率增长较为缓慢。在美国和欧洲，男同性恋者和静脉注射吸毒者仍是主要的风险人群。这种疾病在海地和非洲的异性恋者中很普遍，无论他们生活在本国还是国外。在扎伊尔、卢旺达、赞比亚和乌干达已发现该综合征病例，但其全部范围尚不清楚。与流行病的总体历史一致，该综合征在地理上分散的发病地点的出现可能与人口迁移有关；然而，尚未找到确定起始地点的证据。
