人们在生病时的互动方式可能会对传染病的传播产生深远的影响。为了获得有关非洲这些模式的数据，我们记录了马拉维北部农村地区自我报告的具名联系人和临时接触的机会。我们采访了384名患者和257名照顾者，在三个24小时的时间段内进行了接触：因急性疾病就诊的当天，第二天，以及两周后健康的情况。对于所有年龄段的参与者来说，就诊当天成人接触者的数量和使用公共交通的比例高于就诊后就诊的人。与就诊后第二天相比，Well参与者(2周后)平均多说了0.4次接触者；室内或长期接触者的增加幅度更大。当情况良好时，参与者更有可能参观其他房子并聚集在一起。生病时，他们家里有更多的访客。这些发现可能有助于改进感染传播的模型。
The way persons interact when ill could profoundly affect transmission of infectious agents. To obtain data on these patterns in Africa, we recorded self-reported named contacts and opportunities for casual contact in rural northern Malawi. We interviewed 384 patients and 257 caregivers about contacts over three 24-hour periods: day of the clinic visit for acute illness, the next day, and 2 weeks later when well. For participants of all ages, the number of adult contacts and the proportion using public transportation was higher on the day of the clinic visit than later when well. Compared with the day after the clinic visit, well participants (2 weeks later) named a mean of 0.4 extra contacts; the increase was larger for indoor or prolonged contacts. When well, participants were more likely to visit other houses and congregate settings. When ill, they had more visitors at home. These findings could help refine models of infection spread.
