Abstract

Serum samples collected between 1974 and 1980 out of populations from the States of Pará and Goiás, Brazil, were tested for antibodies against HIV-1 through ELISA, immunofluorescence, and immunoblot. The aim was to describe the possibility of the virus presence in this country before the present epidemic. Four samples from an epidemiologically closed community, the Xicrin indians, gave positive reaction in the ELISA test, but were negative in the confirmatory tests. The negative results suggest the absence of HIV-1, in the groups tested, prior to the 1980's.
