Risk reductions behaviors are especially important during acute/early HIV infection, a period of high transmission risk. We examined how sexual behaviors changed following diagnosis of acute/early HIV infection. Twenty-eight individuals completed structured surveys and in-depth interviews shortly after learning of their infection and 2 months later. Quantitative analyses revealed significant changes after diagnosis, including reductions in total partners and decreases in the proportion of unprotected sex acts occurring with uninfected partners (serosorting). Qualitative findings indicated that these changes were motivated by concerns about infecting others. However, participants were less successful at increasing the frequency with which they used condoms. These results suggest that the initial diagnosis with HIV may constitute an important component of interventions to promote risk reduction during the acute/early stages of the disease.
风险降低行为在急性/早期 HIV 感染期间尤为重要，这是一个高传播风险的时期。我们研究了在诊断出急性/早期 HIV 感染后性行为如何发生变化。28 人在得知感染后的不久后完成了结构化调查和深入访谈，并在 2 个月后再次进行。定量分析显示诊断后发生了显著变化，包括性伴侣总数减少，以及与未感染伴侣发生无保护性行为的比例下降（血清学匹配）。定性研究结果表明，这些变化是出于对感染他人的担忧。然而，参与者在增加使用安全套的频率方面效果较差。这些结果表明，最初诊断出 HIV 可能是在疾病的急性/早期阶段促进风险降低的干预措施的一个重要组成部分。
