fallen, in last decade. A positive outcome of a prevention programme among prostitutes can be found in Sonagachi, a red-light district in Kolkata. The education programme targeted about 5,000 female prostitutes. A team of two peer workers carried out outreach activities including education, condom promotion and follow-up of STI cases. When the project was launched in 1992, 27% of sex workers reported condom use. By 1995 this had risen to 82%, and in 2001 it was 86%. Reaching women who are working in brothels has proven to be quite difficult due to the sheltered and secluded nature of the work, where pimps, Mashis, and brothel-keepers often control access to the women and prevent their access to education, resulting in a low to modest literacy rate for many sex workers. Not only HIV but other infection diseases have been decreased, examined data from 868 prevention projects—serving about 500,000 female sex workers—implemented between 1995 and 2008. The research found that reaching sex workers through prevention programs decreased HIV and syphilis infection rates among young pregnant women tested routinely at government prenatal health clinics. Foreign prostitutes Women and girls from China, Arab countries, Japan, the former Soviet Republics, Bangladesh, Sri Lanka and from other origins have been noted as working as prostitutes in India. In 2015, ten Thai women were arrested in India on prostitution charges for allegedly running two brothels masquerading as massage parlours. In 2013 there were reports of Afghan women being trafficked as prostitutes to India. Uzbek women go to India to work as prostitutes.

Thousands of unregulated work placement agencies reportedly lure adults and children under false promises of employment into sex trafficking. Experts estimate millions of women and children are victims of sex trafficking in India. Traffickers use false promises of employment or arrange sham marriages within India or Gulf states and subject women and girls to sex trafficking. In addition to traditional red light districts, women and children increasingly endure sex trafficking in small hotels, vehicles, huts, and private residences. Traffickers increasingly use websites, mobile applications, and online money transfers to facilitate commercial sex. Children continue to be subjected to sex trafficking in religious pilgrimage centers and by
