Varied potential risks of HIV infection among prostitutes.

To date, most HIV prevention programs targeting North American prostitutes have focused on individual behaviour change, and in particular, the consistent use of condoms between prostitutes and their clients. The organizational and societal level issues which may influence high risk practices within the working and private spheres have received relatively little attention. In addition, most prevention efforts have been limited to targeting the sub-population of street prostitutes. We outline here three different types of prostitutes (street prostitutes, escorts, and prostitutes who work part time in the service sector, i.e. barmaids and erotic massage therapists) known to work in many North American centres. In doing so, we suggest that potential risks of infection vary according to the type of prostitution, and that prevention programs must recognize the diversity in potential risk practices. Differences in the organization of work and working conditions of varied types of prostitutes may, in particular, influence risk practices while working. Some of the individual, organizational and societal level issues which influence risk practices among different types of prostitutes are presented. Much of the research involving HIV and prostitutes has accessed prostitutes at sites where street prostitutes are over-represented. Other studies are based on potentially baised samples as they have recruited prostitutes from medical clinics. Methodologic problems that influence attempts to obtain a representative sample of the prostitute population are discussed.
