Sexually transmitted infections (STIs) and Human Immunodeficiency Virus (HIV) are generally transmitted through sexual contact, during unprotected sexual intercourse, some are also transmitted from mother to child during antenatal, intranatal and postnatal period and through unsafe blood, blood products, donated organs or tissues and contaminated needles, their consequences are more devastating and prevalent among women than men.1

STIs are currently a huge burden of disease and adversely effect the reproductive health of people. It is recognized that risk of getting HIV infection increases manifold in people with current or prior STIs. STIs are linked to HIV transmission as common sexual behaviour put persons at the risk of infection which directly increases the probability of getting and transmitting HIV.2

The STIs / HIV are the global major public health; social and economic problems leading to considerable morbidity, mortality and stigma. Sex workers are one of the link groups for transmission of STIs / HIV, act as a link group to the general population.3, 4

Globally, incidence of STIs in 2008 was an estimated 499 million cases; this figure was not much different from the estimated 448 million cases in 2005. Globally in 2011 an estimated 34 million people were living with HIV and 0.8% of adult aged between 15 and 49 years were living with HIV. In 2011 the incidence of HIV was 2.5 million cases and 1.7 million people were died due to AIDS related causes.5, 6

In India the incidence of STIs was an estimated at around 5% of the adult population in 1999, which implies that about 40 million new STI cases are occurring yearly in the country and community based prevalence study (NACO 2003) showed that over 6% of adult population suffers from STIs, based on these an estimated 30 million adults were infected with STIs in that half of whom were symptomatic. About 60-80% of sex workers in major cities have STIs signifying that regular unprotected sexual intercourse was common.7

In 1986 the first case of AIDS was found in India and after that HIV infection has been reported in all states and union territories. India has the third largest population of people living with HIV/AIDS and HIV spread in India is heterogeneous. According to annual report of National AIDS control organization (NACO) 2011-12; in the year of 2009 it is estimated that India had approximately 1.2 lakh new HIV infection and estimated adult HIV prevalence in India was 0.31%. The adult prevalence was 0.
