[Intra-family transmission of human T-cell lymphotropic virus-1 (HTLV-1) in a cohort of HTLV-1-positive patients (Bénin)].

We are reporting the results of a familial study carried out in Benin in March 1994 within a cohort of HTLV-1 positive subjects. This study aims at appraising the different modes of intra-familial transmission of this retrovirus.

Seropositivity for HIV is always established by Western-blotting and diagnosis of AIDS is based on BANGUI/WHO clinical criteria and positive serologic tests. On June 30, 1993, the cumulative number of AIDS cases reported to the WHO was 12/100000 inhabitants of Benin.
