研究发现,在第二次COVID感染后,青年面临COVID长期风险增加了一倍。 Youth face doubled long COVID risk after second COVID infection, study finds.

美国在《柳叶刀传染病》中公布的一项大型研究发现,儿童和青少年在第二次感染后发展长期COVID的可能性是第一次感染的两倍,在重新感染后每百万人中有1884个病例,在一次感染后每百万人中有904个病例。 A large U.S. study published in The Lancet Infectious Diseases finds children and adolescents are twice as likely to develop long COVID after a second infection compared to a first, with 1,884 cases per million after reinfection versus 904 per million after one infection. 该研究分析了 2022 年 1 月至 2023 年 10 月期间（在 Omicron 浪潮期间）40 家医院的 465,000 多名青少年的数据，将再感染与心肌炎、血栓、肾脏损伤以及疲劳、头痛和心脏不规则等持续症状的风险显着增加联系起来。 Analyzing data from over 465,000 youth across 40 hospitals between January 2022 and October 2023—during the Omicron wave—the research links reinfection to significantly higher risks of myocarditis, blood clots, kidney damage, and ongoing symptoms like fatigue, headaches, and heart irregularities. 作为NIH的RECOVER倡议的一部分,调查结果表明,无论年龄、性别、种族或接种疫苗状况如何,这种风险依然存在,对儿科感染总是轻度的观念提出了挑战。 The findings, part of the NIH’s RECOVER Initiative, show the risk persists regardless of age, gender, race, or vaccination status, challenging the idea that pediatric infections are always mild. 专家强调疫苗接种和预防措施仍是减少感染和长期健康影响的关键。 Experts stress vaccination and preventive measures remain key to reducing infection and long-term health impacts.
