The Future of a Vaccine, and New Warnings for Asia (1)

A new study says Asia must do more to prevent AIDS, or the number of people infected with H.I.V. could double by two thousand twenty. Today about five million people in Asia are living with the virus that causes AIDS.

An estimated three hundred thousand people died of H.I.V.-related diseases in Asia last year. At current rates, that number could rise to almost five hundred thousand.The United Nations program on H.I.V./AIDS requested the study, led by Indian economist Chakravarthi Rangarajan.

The report says three main groups are driving the spread of AIDS in Asia. One group is sex workers and the men who use them. Another is injection drug users who share needles. And the third group are men who have unprotected sex with other men.

Researchers estimate that as many as ten million women in Asia sell sex. At least seventy-five million men buy on a regular basis. In many Asian countries, these men, and their female partners, represent the largest group of people living with H.I.V. The study found that AIDS is the most likely cause of death and lost work days for people in Asia between the ages of fifteen and forty-four.

一项新的研究表明，亚洲应该在防治艾滋病中做更多的工作，否则到2020年，感染艾滋病病毒的患者数量将翻倍。在亚洲，共有500万人正受到引起艾滋病的病毒的感染。

去年估计在亚洲有30万人死于艾滋病相关疾病。以现有的感染率，死亡人数将上升至近50万。联合国关于HIV/AIDS的项目要求进行研究，该研究由印度经济学家Chakravathi Rangarajan主持。

报告指出主要有三类人群推动了艾滋病在亚洲的传播。第一组人群是性工作者及那些接受服务的男性。另一群是共用针头的药瘾者。第三类是未采取保护措施而与其他男性性交的男性。

研究者估计在亚洲多达1000万妇女从事性工作。至少7500万男性定期花钱接受这种服务。在许多亚洲国家，这些男性和他们的女性（性）伙伴是患有艾滋病的主要人群。研究发现在亚洲，艾滋病是最可能造成死亡和导致15岁-44岁之间人群损失工作日的原因。
