HIV and AIDS is a cross cutting issue in the present situation rather than a health issue. One of the most at risk groups is the clients of female workers who frequently have risk behaviours like having sex with female sex workers. The sexual behaviour among these clients depends upon their attitude, knowledge and perception, which also influence several internal and external factors. In our study, the clients of the female sex workers had some extent of knowledge about the condom, sexually transmitted infections and HIV/AIDS. They were made aware on these by different organizations who were working in the field of HIV and AIDS, but still they intended to practise unsafe sex with the female sex workers.
