The COVID-19 pandemic is a major challenge for health systems, citizens and policymakers worldwide. It is not known how many people are affected with longer term sequelae after acute COVID-19 and a wide range of prevalence estimates have been reported with a high heterogeneity between studies.
We designed a cross-sectional study to estimate the prevalence of post COVID-19 conditions in a community setting. We selected a random sample of 579 individuals from three different primary health care centers and collected information on symptoms through a standardized questionnaire.
Our main study finding was an overall population prevalence of 14.34% (95% CI 11.58-17.46%) of post COVID-19. Only 9% of patients were hospitalized in our study. Prevalence was higher in women than men (15.63% versus 13.06%) and the most frequent persistent symptoms were fatigue (44.6%), smell impairment (27.7%) and dyspnea (24.09%).
The prevalence of post COVID-19 condition was lower than expected according to other studies published in the literature. The prevalence was higher in women than men, and the most frequent persistent symptoms were fatigue, smell impairment, and dyspnea.
COVID-19 大流行是全球卫生系统、公民和政策制定者面临的重大挑战。目前尚不清楚有多少人在急性 COVID-19 后会出现长期后遗症，而且已有广泛的流行率估计报告，但研究之间存在很高的异质性。
我们设计了一项横断面研究，以估计社区环境中 COVID-19 后疾病的流行率。我们从三个不同的初级保健中心中随机选择了 579 名个体，并通过标准化问卷收集了症状信息。
我们的主要研究发现是 COVID-19 后总体人群的流行率为 14.34%（95%CI 11.58-17.46%）。在我们的研究中，仅有 9%的患者住院。女性的患病率高于男性（15.63%比 13.06%），最常见的持续症状是疲劳（44.6%）、嗅觉障碍（27.7%）和呼吸困难（24.09%）。
根据文献中发表的其他研究，COVID-19 后疾病的流行率低于预期。女性的患病率高于男性，最常见的持续症状是疲劳、嗅觉障碍和呼吸困难。
