Objectives: This study tried to determine human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevalences among female commercial sex workers in Mexico City.
Methods: A sampling frame was constructed that included bars, massage parlors, and street corners.
Results: Prevalences for Treponema pallidum, herpes simplex virus type 2, HIV, Neisseria gonorrhoeae, and Chlamydia trachomatis were 6.4%, 65%, 0.6%, 3.7%, and 11.1%, respectively. A significant association was found between higher STD frequencies and working at street sites.
Conclusions: Most STD frequencies were lower in comparison with rates found for female sex workers in other countries. However, preventive programs against STD/ HIV are needed in this population.
