Understanding SARS-CoV-2 infection in populations at increased risk for poor health is critical to reducing disease. We describe the epidemiology of SARS-CoV-2 infection in Kakuma Refugee Camp Complex, Kenya. We performed descriptive analyses of SARS-CoV-2 infection in the camp and surrounding community during March 16, 2020‒December 31, 2021. We identified cases in accordance with national guidelines.We estimated fatality ratios and attack rates over time using locally weighted scatterplot smoothing for refugees, host community members, and national population. Of the 18,864 SARS-CoV-2 tests performed, 1,024 were positive, collected from 664 refugees and 360 host community members. Attack rates were 325.0/100,000 population (CFR 2.9%) for refugees,150.2/100,000 population (CFR 1.11%) for community, and 628.8/100,000 population (CFR 1.83%) nationwide. During 2020-2021, refugees experienced a lower attack rate but higher CFR than the national population, underscoring the need to prioritize SARS-CoV-2 mitigation measures, including vaccination.
了解易患不良健康状况人群中 SARS-CoV-2 感染的情况对于减少疾病至关重要。我们描述了肯尼亚卡卡马难民营综合体内 SARS-CoV-2 感染的流行病学情况。我们对 2020 年 3 月 16 日至 2021 年 12 月 31 日期间营地和周边社区的 SARS-CoV-2 感染进行了描述性分析。我们按照国家指南确定了病例。我们使用局部加权散点平滑法估计了难民、收容社区成员和全国人口随时间推移的病死率和发病率比。在进行的 18864 次 SARS-CoV-2 检测中，有 1024 次呈阳性，来自 664 名难民和 360 名收容社区成员。难民的发病率为 325.0/100000 人口（病死率 2.9%），社区为 150.2/100000 人口（病死率 1.11%），全国为 628.8/100000 人口（病死率 1.83%）。在 2020-2021 年期间，难民的发病率较低，但病死率高于全国人口，这突显了需要优先考虑 SARS-CoV-2 缓解措施，包括疫苗接种。
