The aim of Cochrane co-operation net is to make,reserve and distribute systemic evaluation about health protection measures.

In 1996,disk edition of Cochrane library was formally published.

With this in mind, the researchers then reanalysed data from knowingly HIV-positive heterosexual subjects in Uganda and Zambia who had HIV-negative sexual partners. Those with a viral load of one million particles per millilitre were more than ten times more likely to accidentally infect their partners each year than those with a load of one thousand.But when the researchers calculated the transmission potential over the entire predicted asymptomatic period, those with viral loads between ten thousand and a hundred thousand copies per millilitre of blood were the most likely to infect their partners. HIV-positive subjects with viral counts of 50,000 infected roughly twice as many people as those with counts of one million.

伦敦帝国学院流行病学家Christophe Fraser和他的同事对收集于1982年到1993年之间的100多例HIV阳性的男性同性恋者的数据进行分析，并结合分析来自乌干达和赞比亚的已知有HIV阴性性伴侣的HIV阳性异性恋受调查者的资料，他们发现中度病毒负荷而无症状的HIV携带者更易播散HIV，这是因为中度病毒负荷的HIV携带者的无症状期较长，而那些高病毒负荷而无症状的HIV携带者虽然传染性稍强，但其传染的持续时间却很短，并且在未经治疗的HIV携带者个体中中度病毒负荷是最常见的人群。
