This text presents the results of an analysis of the distribution and evolution of the HIV2 infection in Africa South of Sahara. The serological data collected in selected groups of the population suggest that the virus is very rare in the East and the South of the continent, except in Mozambic where it is found everywhere, but on a low level. The infection is also rarely depisted in West-Central Africa; however an epidemic could affect the North of angola. HIV2 is probably an old host of some West African collectivities. Now the infection is often sporadic in the general population except in a little regional foci in Guinea-Bissau. On the contrary, high prevalences are observed in many groups of prostitutes. The epidemiological situation has been stable since 1985-86. At least in West Africa, the only new fact of the recent past could be that the infection became apparent to the physicians.
本文展示了对撒哈拉以南非洲地区HIV2感染分布及演变情况的分析结果。在选定人群组中收集的血清学数据表明，该病毒在非洲大陆东部和南部非常罕见，莫桑比克除外，该国各地均有发现，但感染率较低。在中西部非洲也很少检测到该感染；然而，一场疫情可能会影响安哥拉北部。HIV2可能是一些西非群体的古老宿主。目前，除几内亚比绍的一些小区域疫源地外，该感染在普通人群中通常呈散发状态。相反，在许多妓女群体中观察到高感染率。自1985 - 1986年以来，流行病学情况一直稳定。至少在西非，近期唯一的新情况可能是医生们开始注意到这种感染。
