A complex picture is emerging, along with urgent priorities for future research Covid-19 cases and deaths have decreased globally,1 yet, the long term consequences of infection, including post-covid-19 condition (often known as long covid), are still being managed. Most people who have covid-19 recover soon after the acute phase of the disease but others experience persistent health problems for months or longer, and these problems can impact quality of life and ability to work.23456 Understanding the trajectory of symptom burden and recovery from post-covid-19 condition is crucial for policy making, treatment decisions, and care coordination. Early studies reported widely varying estimates of post-covid-19 condition prevalence and symptom trajectories, mainly due to differences in sample representativeness and survey designs. As commented on by previous work,236 research has been limited by: data sources not representative of the general infected population because much covid data are based on patients admitted to hospital; scarcity of information on symptom trajectory because population level studies rarely survey a comprehensive set of symptoms or the change in their severity; absence of a comparable …

了解 covid-19 后状况的负担

复杂的情况正在出现，随着未来研究的紧迫优先事项 Covid-19 病例和死亡人数在全球范围内有所减少，1 然而，感染的长期后果，包括 covid-19 后状况（通常称为 long covid），仍然存在被管理。大多数患有 covid-19 的人在疾病的急性期后很快就会康复，但其他人会经历持续数月或更长时间的健康问题，这些问题会影响生活质量和工作能力。23456 了解症状负担和康复的轨迹covid-19 后的状况对于决策、治疗决定和护理协调至关重要。早期研究报告了对 covid-19 后疾病流行率和症状轨迹的广泛估计，这主要是由于样本代表性和调查设计的差异。正如之前的工作所评论的那样，236 研究受到以下因素的限制：数据来源不能代表一般感染人群，因为许多 covid 数据都是基于入院患者；缺乏关于症状轨迹的信息，因为人群水平的研究很少调查一组全面的症状或其严重程度的变化；没有可比性……
