Prostitution law
However, sex worker activists and organizations distinguish between human trafficking and legitimate sex work, and assert the importance of recognizing that trafficking is not synonymous with sex work. The Sex Workers Alliance Ireland organization explains: "victims of human trafficking may be forced to work in industries such as agriculture, domestic service as well as the sex industry. It is critical to distinguish human trafficking, which is a violation of human rights, from voluntary migration." The Open Society Foundations organization states: "sex work is done by consenting adults, where the act of selling or buying sexual services is not a violation of human rights. In fact, sex workers are natural allies in the fight against trafficking. The UNAIDS Guidance Note on HIV and Sex Work recognizes that sex worker organizations are best positioned to refer people who are victims of trafficking to appropriate services."
Migrant sex work
State response may differ based on anti-human trafficking attitudes that often prevail. Some states are sympathetic to migrant sex workers who are considered to be victims of human trafficking and not voluntary sex workers. Some governments, such as that of the United States, provide legal and health services to individuals who engage in commercial sex if these individuals are proven and officially certified by law enforcement to be victims of human trafficking.
