Governments and the United Nations have recognised the need to address the legal and policy barriers and stigma and discrimination faced by sex workers in order to respond to the HIV epidemic. In many countries, laws, policies and practices against sex workers limit their right to basic social economic rights such as access to education, health care, housing, banking facilities, inheritance, property and legal services. They may also lack citizenship or legal status, resulting from migration or unfavourable regulations, which can lead to exclusion of sex workers from health services, social programmes and communities.
