科学家提出了一种制止艾滋病流行的全新方法，但是评论者说，执行这种方法可能有人权方面的问题。

根据发表在《柳叶刀》杂志上的这种方法，生活在艾滋病最严重地区——例如撒哈拉以南非洲——的人们将每年检测艾滋病，发现呈阳性的人们将立即服用抗逆转录病毒药物。
这种方法有可能大幅度减少新发感染，因为艾滋病药物降低了体内病毒水平，让传染的可能性降低。这组作者估计，这有可能在50年内把感染率降低1%以下。到2016年死亡率可能下降到每年1/1000。
但是由于这些药物的毒性和副作用，让人们立即服用抗逆转录病毒药物的做法具有争议。目前感染者只有在需要的时候才服用抗逆转录病毒药物，改变这种做法可能带来一个伦理问题，即为了公共利益而伤害患者个体。
《柳叶刀》论文的作者说，他们的这种策略是一个供讨论用的数学模型，但是当疫苗和杀微生物剂失败的时候，它提供了一个新的选项。
他们说，这样的一个策略可能需要初期大量投入，但是降低传染率将导致预防、护理和治疗的开支大大降低。

Scientists put an end to a new AIDS epidemic, but critics said that the implementation of this approach may be the issue of human rights.

According to the publication of "The Lancet" magazine on the method, the most serious AIDS live in the region - such as sub-Saharan Africa - will be the detection of AIDS every year and found that positive people will be taking anti-retroviral drugs .
This approach may have made a significant reduction in new infections, AIDS drugs to reduce the level of virus in the body so that the possibility of reducing transmission. This group is estimated that the author, which could in 50 years to reduce the infection rate of less than 1%. By 2016 the annual death rate may be reduced to 1 / 1000.
However, due to the toxicity of these drugs and side effects, people immediately take anti-retroviral drugs is controversial. At present, only infected people in need when taking anti-retroviral drugs, to change this practice may have an ethical problem, that is, in order to harm the public interest and individual patients.
"The Lancet" said the authors, their strategy is for discussion by the mathematical model, but when vaccines and microbicides failure, it provides a new option.
They said such a strategy may require a large number of initial investment, but to reduce the rate of infection will lead to prevention, care and treatment costs much lower.
