2022 年 1 月 6 日，英国政府国家统计局 (ONS) 发布了最新的代表性调查报告，显示英国长效新冠肺炎流行情况。截至 2021 年 12 月 6 日，大约有 1·2.66 亿生活在英国的人自我报告长期感染新冠病毒（95% CI 1·228–1·304；占总人口的 2%），定义为在首次确诊或疑似感染 COVID-19 后症状持续超过 4 周。在这些人中，有 892 000 人 (70%) 至少在 12 周前确诊或疑似患有 COVID-19。疲劳是报告的最常见症状，其次是嗅觉丧失、呼吸短促和注意力不集中。国家统计局报告中的数字足够高，值得人们停下来关注，特别是考虑到所有亚人群中都报告了长期感染新冠病毒的情况，其中包括约 77 000 名 2-16 岁儿童和 134 000 名 17-25 岁儿童。然而，成人和儿童感染后长期感染新冠病毒的真实患病率仍存在不确定性。 ONS 之前的一篇文章表明，2020 年 4 月至 2021 年 8 月期间在英国检测出 COVID-19 感染呈阳性的人中，有 3% 至 12% 在初次感染后 12 周出现新的或持续的症状，包括在急性期没有症状的人。
On Jan 6, 2022, the UK Government’s Office of National Statistics (ONS) published their latest report on the prevalence of long COVID in the UK from a representative survey. As of Dec 6, 2021, around 1· 266 million people living in the UK had self-reported long COVID (95% CI 1· 228–1· 304; 2% of the total population), defined as symptoms persisting for more than 4 weeks after the first confirmed or suspected COVID-19 infection. Of these individuals, 892 000 (70%) had confirmed or suspected COVID-19 at least 12 weeks previously. Fatigue was the most common symptom reported, followed by loss of smell, shortness of breath, and difficulty concentrating.The numbers in the ONS report are high enough to give pause for concern, particularly as long COVID was reported in all sub-populations, including around 77 000 children aged 2–16 years and 134 000 people aged 17–25 years. Yet there is still uncertainty about the true prevalence of long COVID in adults and children following infection. A previous ONS article suggested that, of individuals who tested positive for COVID-19 infection in the UK between April, 2020, and August, 2021, between 3% and 12% had new or ongoing symptoms 12 weeks after the initial infection, including people who were not symptomatic during the acute phase.
