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。
