摘要：OBJECTIVES. This paper measured the extent to which human immunodeficiency virus (HIV) infection has spread among the male working-class population of Santos, Brazil. METHODS. Questionnaires on risk behaviors and blood tests were administered to a random sample (n = 395) of male port workers employed by the Santos Port Authority. RESULTS. Although the rate of HIV infection among these men- the working-class male population of Santos-remains low (1.1%), self-reported behavioral risks for HIV infection are common. CONCLUSIONS. There is still time to prevent a widespread outbreak of HIV infection among the hetero-sexual population of Santos and of the transportation corridors emanating from that city.
