HIV/AIDS and human trafficking threaten human security and human development. Millions of women and girls have been trafficked across borders and within countries in recent years, making human trafficking a global industry that generates an estimated five to seven billion U.S. dollars each year. It is estimated that 300,000 to 450,000 people are trafficked within Asia each year, of which more than half take place in South Asia. More information about human trafficking on the website of UNDP.
