BACKGROUND
Few studies have focused on the effects of COVID-19 on African populations. During the first epidemic wave in Senegal (May 1 to July 31, 2020), COVID-19 cases were isolated in treatment centers of epidemics (TCEs). We described the demographics and outcomes of COVID-19 cases in TCEs.
PATIENTS AND METHODS
All cases with laboratory-confirmed COVID-19 in Thiès medical region of Senegal were included.
RESULTS
COVID-19 was confirmed in 600 cases. Median age of cases (men: 357, 59.5%; women: 243, 40.5%) was 34.0years. The incidence was 12 per 100,000 inhabitants per month. Overall, 46 (7.7%) cases had a severe or critical form of the disease, and nine of them died. Of 455 cases quarantined in non-hospital TCEs, 340 (74.7%) had no symptom and 115 (25.3%) had mild or moderate symptoms.
CONCLUSION
In this African retrospective cohort, COVID-19 cases were young and mostly asymptomatic with a low case fatality rate.
背景
针对 COVID-19 对非洲人群影响的研究较少。在塞内加尔的第一轮疫情（2020 年 5 月 1 日至 7 月 31 日）期间，COVID-19 病例被隔离在传染病治疗中心（TCEs）。我们描述了 TCEs 中 COVID-19 病例的人口统计学和结局。
患者和方法
所有在塞内加尔蒂埃斯医疗区确诊的 COVID-19 病例均被纳入研究。
结果
共确诊 COVID-19 病例 600 例。病例的中位年龄（男性：357 岁，59.5%；女性：243 岁，40.5%）为 34.0 岁。每月每 100,000 居民发病率为 12 例。总体而言，46 例（7.7%）病例为严重或危重症，其中 9 例死亡。在非医院 TCEs 中隔离的 455 例病例中，340 例（74.7%）无症状，115 例（25.3%）有轻度或中度症状。
结论
在这项非洲回顾性队列研究中，COVID-19 病例较为年轻，大多数为无症状，病死率较低。
