Lesotho has the third highest rate of HIV prevalence in the world. One of the factors accounting for this trend is thought to be ubiquitous labour migration in the country. This article uses data collected among migrant labour women in Maseru (N = 30) to investigate possible factors for the spread of HIV among them. A high rate of multiple concurrent sexual relationships, coupled with lack of commitment to condom use, was found among participants. This article proposes social action to pressure industry merchants to facilitate regular meetings of migrants with regular sexual partners.
