Still a tough battle to win fight against HIV

Thirty years after the first World AIDS Day was marked on Dec 1, 1988, HIV remains one of the world's major infectious killers.

Worldwide more than 77 million people are infected with the virus, and more than 35 million have died of AIDS-related diseases so far, according to the United Nations.

In China, 1.25 million people - or about 9 in every 10,000 people - are living with HIV/AIDS, according to the Chinese Center for Disease Control and Prevention.
