Post-COVID Conditions

As part of an ongoing partnership with the Census Bureau, the National Center for Health Statistics (NCHS) recently added questions to assess the prevalence of post-COVID-19 conditions (long COVID), on the experimental Household Pulse Survey. This 20-minute online survey was designed to complement the ability of the federal statistical system to rapidly respond and provide relevant information about the impact of the coronavirus pandemic in the U.S. Data collection began on April 23, 2020. Beginning in Phase 3.5 (on June 1, 2022), NCHS included questions about the presence of symptoms of COVID that lasted three months or longer. Phase 3.5 will continue with a two-weeks on, two-weeks off collection and dissemination approach.

Estimates on this page are derived from the Household Pulse Survey and show the percentage of adults aged 18 and over who a) as a proportion of the U.S. population, the percentage of adults who EVER experienced post-COVID conditions (long COVID). These adults had COVID and had some symptoms that lasted three months or longer; b) as a proportion of adults who said they ever had COVID, the percentage who EVER experienced post-COVID conditions; c) as a proportion of the U.S. population, the percentage of adults who are CURRENTLY experiencing post-COVID conditions. These adults had COVID, had long-term symptoms, and are still experiencing symptoms; d) as a proportion of adults who said they ever had COVID, the percentage who are CURRENTLY experiencing post-COVID conditions; and e) as a proportion of the U.S. population, the percentage of adults who said they ever had COVID.

作为与国家统计局持续合作的一部分，国家健康统计中心（NCHS）近期在实验性的家庭脉搏调查中增加了评估新冠后状况（长期新冠）流行率的问题。该时长为20分钟的在线调查旨在补充联邦统计系统的快速响应能力，并提供有关美国冠状病毒大流行影响的关联信息。数据收集始于2020年4月23日。自第3.5阶段（2022年6月1日开始），NCHS纳入了关于新冠症状持续三个月或更长时间的问题。第3.5阶段将继续采用两周收集、两周发布的方式。本页的估计值源自家庭脉搏调查，显示了18岁及以上成年人中，a）作为美国人口比例，曾经经历新冠后状况（长期新冠）的成年人比例；b）在声称曾经感染新冠的成年人中，曾经经历新冠后状况的比例；c）作为美国人口比例，目前正在经历新冠后状况的成年人比例。这些成年人感染了新冠，有长期症状，且仍在经历症状；d）在声称曾经感染新冠的成年人中，目前正在经历新冠后状况的比例；以及e）作为美国人口比例，声称曾经感染新冠的成年人比例。
