The five-day global conference, which began on July 22, is an annual congregation of organisations and agencies from across the world engaged in controlling AIDS.
Under the banner of Global Hub of the International AIDS Conference, over 550 representatives of sex workers from 47 countries are attending the event in Kolkata which is being hosted by the Durbar Mahila Samanwaya Committee.
The conference will deliberate on the 'Seven Freedoms' - the right to move, work, access to healthcare, participate, organise, be free of violence and discrimination - without which the community of sex workers cannot reduce their vulnerability to HIV.
Held every two years, the International AIDS Conference returned to the United States for the first time since 1990 after being kept away by laws that barred people with HIV from travelling to the country.
However, there was satellite communication between the two conferences to enable the sex workers' and other stakeholders' to participate from Kolkata.
