Abstract

OBJECTIVES

To assess disease trends, testing practices, community surveillance, case-fatality and excess deaths in children as compared with adults during the first pandemic peak in England.

SETTING

England.

PARTICIPANTS

Children with COVID-19 between January and May 2020.

MAIN OUTCOME MEASURES

Trends in confirmed COVID-19 cases, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positivity rates in children compared with adults; community prevalence of SARS-CoV-2 in children with acute respiratory infection (ARI) compared with adults, case-fatality rate in children with confirmed COVID-19 and excess childhood deaths compared with the previous 5 years.

RESULTS

Children represented 1.1% (1,408/129,704) of SARS-CoV-2 positive cases between 16 January 2020 and 3 May 2020. In total, 540 305 people were tested for SARS-COV-2 and 129,704 (24.0%) were positive. In children aged <16 years, 35,200 tests were performed and 1408 (4.0%) were positive for SARS-CoV-2, compared to 19.1%-34.9% adults. Childhood cases increased from mid-March and peaked on 11 April before declining. Among 2,961 individuals presenting with ARI in primary care, 351 were children and 10 (2.8%) were positive compared with 9.3%-45.5% in adults. Eight children died and four (case-fatality rate, 0.3%; 95% CI 0.07% to 0.7%) were due to COVID-19. We found no evidence of excess mortality in children.

CONCLUSIONS

Children accounted for a very small proportion of confirmed cases despite the large numbers of children tested. SARS-CoV-2 positivity was low even in children with ARI. Our findings provide further evidence against the role of children in infection and transmission of SARS-CoV-2.

摘要

目的

评估英格兰首次大流行高峰期间儿童与成人相比的疾病趋势、检测实践、社区监测、病死率和超额死亡。

设置

英格兰。

参与者

2020 年 1 月至 5 月期间患有 COVID-19 的儿童。

主要观察指标

确诊 COVID-19 病例的趋势,儿童与成人相比 SARS-CoV-2 阳性率;儿童急性呼吸道感染(ARI)与成人相比 SARS-CoV-2 的社区流行率,儿童确诊 COVID-19 的病死率以及与前 5 年相比儿童超额死亡。

结果

2020 年 1 月 16 日至 2020 年 5 月 3 日,儿童占 SARS-CoV-2 阳性病例的 1.1%(1408/129704)。共有 540305 人接受了 SARS-COV-2 检测,129704 人(24.0%)呈阳性。在年龄<16 岁的儿童中,进行了 35200 次检测,有 1408 例(4.0%)SARS-CoV-2 检测呈阳性,而成年人的阳性率为 19.1%-34.9%。儿童病例从 3 月中旬开始增加,4 月 11 日达到高峰后下降。在初级保健中出现 ARI 的 2961 人中,有 351 人是儿童,10 人(2.8%)呈阳性,而成年人的阳性率为 9.3%-45.5%。有 8 名儿童死亡,其中 4 名(病死率为 0.3%;95%CI 0.07%至 0.7%)是由 COVID-19 引起的。我们没有发现儿童死亡人数异常增加的证据。

结论

尽管接受检测的儿童人数众多,但儿童仅占确诊病例的很小一部分。即使是患有 ARI 的儿童,SARS-CoV-2 阳性率也很低。我们的发现进一步证明儿童在感染和传播 SARS-CoV-2 方面的作用不大。
