Human rights violations perpetrated by police and military personnel in many countries are correlated with decreased access to public health services and increased practices of risky behavior among members of vulnerable groups, such as women and female sex workers. These practices are especially widespread in settings with a weak rule of law and low levels of police and military management and professionalism. Police abuse in this context has been linked to a wide range of risky behaviors and health outcomes, including post-traumatic stress disorder (PTSD), and substance abuse. Extortion of sexual services and police sexual abuse have been linked to a decrease in condom use and an elevated risk of STI and HIV infections among vulnerable groups.
