37 Levels of HIV infection seem to be low (less than 1%) amongst sex workers who do not
inject drugs. However, for those who do
inject drugs the risk is often significantly higher. According to a study carried out in three cities in the Netherlands, the HIV prevalence among female sex workers who injected drugs was 13.8%, while it was 1.5% amongst other female sex workers.38
In many areas, it also seems that male and transgender sex workers are more vulnerable to HIV than female sex workers.
