Barmaids are among the high-risk group of infection of sexually transmitted diseases including HIV/AIDS. Most barmaids are young women who migrate from rural areas with a purpose to engage in formal employment to earn a living. However, since most of them have low levels of education and are unskilled they end up in low income earning jobs including working as barmaids. Due to the nature of their work, they are placed at a higher risk of involving themselves in risky sexual behaviour undertakings. Limited studies in Tanzania have examined sexual behaviour of barmaids and the risks involved.
