A new study says Asia must do more to prevent AIDS, or the number of people infected with HIV could double by 2020. Today about 5 million people in Asia are living with the virus that causes AIDS.

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。

An estimated 300,000 people died of HIV related diseases in Asia last year. At current rates, that number could rise to almost 500,000. The United Nations program on HIV/AIDS requested the study led by Indian economists Chakravathi Rangarajan.

去年亚洲估计有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的项目要求印度经济学家Chakravathi Rangarajan主持了这项研究。

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

报告指出3类主要人群促进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。

Researchers estimate that as many as 10 million women in Asia sell sex. At least 75 million men buy on the regular bases (basis). In many Asia countries, these men, and their female partners, represent the largest group of people living with HIV. The study found that AIDS is the most likely cause of death and lost work day for people in Asia between the ages of 15 and 44.

研究者估计在亚洲多达1000万妇女从事性工作。至少750万男性通常会购买这种服务。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，艾滋病是最容易导致死亡和年龄在15岁至44岁亚洲人群损失工作日的原因。
