Coimbatore, June 15 (ANI): Union Finance Minister P. Chidambaram said on Sunday that sex education is must to control HIV-AIDS.

He said this as he inaugurated an orphanage for HIV infected children in Coimbatore.

Chidambaram also said that the migratory labourers, lorry drivers and above all sex workers are the most vulnerable sections of the society.

"It is spreading very rapidly among lorry drivers, migrant labourers, who keep on traveling from one place to another. Moreover, the sex workers who are carriers of this deadly disease," said Chidambaram.

He also exhorted people to engage themselves constructively and help the Non-Governmental Organizations (NGO), which are battling against this menace.

The number of people estimated to be living with HIV-AIDS in India is about 2.47 million.

Yet over 40 per cent of Indian women have not heard of AIDS, creating a dangerous combination of lack of knowledge and greater sexual activity. (ANI)
