Long COVID is a condition encompassing a wide range of health problems that emerge, persist, or return following COVID-19. CDC analyzed national repeat cross-sectional Household Pulse Survey data to estimate the prevalence of long COVID and significant related activity limitation among U.S. adults aged ≥18 years by age group. Data from surveys completed between June 1-13, 2022, and June 7-19, 2023, indicated that long COVID prevalence decreased from 7.5% (95% CI = 7.1-7.9) to 6.0% (95% CI = 5.7-6.3) among the overall U.S. adult population, irrespective of history of previous COVID-19, and from 18.9% (95% CI = 17.9-19.8) to 11.0% (95% CI = 10.4-11.6) among U.S. adults reporting previous COVID-19. Among both groups, prevalence decreased from June 1-13, 2022, through January 4-16, 2023, before stabilizing. When stratified by age, only adults aged <60 years experienced significant rates of decline (p<0.01). Among adults reporting previous COVID-19, prevalence decreased among those aged 30-79 years through fall or winter and then stabilized. During June 7-19, 2023, 26.4% (95% CI = 24.0-28.9) of adults with long COVID reported significant activity limitation, the prevalence of which did not change over time. These findings help guide the ongoing COVID-19 prevention efforts and planning for long COVID symptom management and future health care service needs.
长新冠是一种涵盖广泛健康问题的病症,这些问题在 COVID-19 后出现、持续或复发。CDC 分析了全国重复横断面家庭脉搏调查数据,以按年龄组估计美国≥18 岁成年人长新冠和显著相关活动受限的患病率。2022 年 6 月 1 日至 13 日和 2023 年 6 月 7 日至 19 日完成的调查数据表明,无论是否有 COVID-19 既往史,长新冠的总体患病率从美国成年人口的 7.5%(95%CI=7.1-7.9)下降到 6.0%(95%CI=5.7-6.3),而报告有 COVID-19 既往史的美国成年人的患病率从 18.9%(95%CI=17.9-19.8)下降到 11.0%(95%CI=10.4-11.6)。在这两个群体中,患病率从 2022 年 6 月 1 日至 13 日下降到 2023 年 1 月 4 日至 16 日,然后趋于稳定。按年龄分层,只有年龄<60 岁的成年人经历了显著的下降率(p<0.01)。在报告有 COVID-19 既往史的成年人中,30-79 岁年龄组的患病率在秋季或冬季下降,然后趋于稳定。在 2023 年 6 月 7 日至 19 日期间,26.4%(95%CI=24.0-28.9)的长新冠成年人报告存在显著的活动受限,其患病率没有随时间变化。这些发现有助于指导当前的 COVID-19 预防工作以及长新冠症状管理和未来医疗保健服务需求的规划。
