The geographical analysis of the main data on the HIV1 epidemic in Central Africa shows a frontline which has not moved significantly since 1985. The absence of a progressive increase between the countries, demonstrating a discontinuity in space, combined with the observed human and physical continuity within the areas, raises several questions. Are the low-rate areas facing only a simple delay in the diffusion, or is there a real difference between the epidemiological patterns of HIV1 in the two areas7quest; The last hypothesis would impose a revision of the concept of an homogeneous pattern in the epidemiology of HIV1 in Africa. The need for further research is emphasized with the aim of precisely targeting preventive intervention.
