The Women’s Professional of the Sex (WPS) constitute a vulnerable population to the acquisition of sexually transmissible illnesses (STI) in virtue of the type of activity that they play. The present work had as objective to describe the serumprevalency of the infection and the molecular characterization of the HIV and the HTLV of WPS of the State of Pará, Brazil. Blood sample’s of 339 WPS were collected, being 105 proceeding from the city of Barcarena, 31 of the city of Augusto Correa, 98 of the city of Bragança and 105 of the city of Belém, in the period of April of 2005 the August of 2006. All the plasma samples had been tested for the presence of antibodies anti-HTLV-1/2 and anti-HIV-1/2, by means of the use of a immune enzimatic assay. The prevalence of the HIV-1 and the HTLV-1 in the studied population was of 2,36% and 1,77%, respectively. The amplification of the gene pro of the HIV-1 disclosed subtypes B and F, whereas the samples of HTLV, had been classified as HTLV-1 of the Cosmopolita subtype of the Transcontinental sub-group. It had a significant association of the infection for the HIV-1 with the age band, the number of partners per week and with the capricious use of condoms. However, the infection for the HTLV-1 alone showed significant association in relation to the capricious use of condom. The sexual relation was the most likely way of acquisition of the infection for the two viral agents, considering that the report of use of injective drugs was rare. Being thus, the WPS need bigger attention of the public agencies of health, specially in relation to the prevention and monitoring of transmissible agents by sexual pathways, as these can be important in the acquisition and dissemination of these agents.
