儿童感染COVID-19的病例增长，医生们正在研究潜在的长期影响

根据儿童医院协会和美国儿科学会发布的最新报告，儿童感染COVID-19的病例现在占美国所有病例的9%，高于三月份的2%。根据来自49个州的报道，自7月9日以来，COVID-19儿童病例数量已经翻了一番，截至8月13日，共有406,109人感染。

在成年人中，感染COVID-19最令人烦恼的一个影响，就是会出现所谓的长途（long-haul）病例——最初症状为中等的人，会长达数个月出现症状，有时病情还会随着时间的推移而恶化。现在，医生警告称，儿童可能比最初认为的还要更容易受到COVID-19的侵害。医生表示，大部分儿童患有轻度疾病，甚至没有症状；但有些报告的症状持续了数周，或者出现了病毒后综合症。报告的症状包括发烧、咳嗽、头痛、呼吸急促和胃肠道问题。

杜克大学医学中心小儿传染病学助理教授马修·凯利（Matthew Kelly）负责监管北卡罗来纳州400多名COVID-19呈阳性或亲密接触过呈阳性病例的儿童。根据其上周六发布的初步结果，虽然大多数青少年的症状在一周内即可缓解，但25%的患者在12天后仍有症状，而10%的患者在17天后仍出现症状。到目前为止，感染COVID-19的儿童的主要并发症是多系统炎症综合症（MIS-C）。这是一种严重的炎症综合症，包括心脏和大脑在内的身体部位可能会发炎，引起发烧、胃痛、皮疹和胃肠道炎症状。根据CDC数据，至少有570例MIS-C病例。儿童们通常在感染后2到4个星期出现综合症，常常需要住院治疗。

As more children become infected with Covid-19, doctors are paying closer attention to potential long-term effects. In adults, one of Covid’s most troubling effects has been so-called long-haul cases, in which people whose illness initially seemed moderate end up having symptoms for months, sometimes getting worse over time. Now as doctors warn that children may be more vulnerable to the virus than initially believed, researchers are looking more closely at longer-term symptoms in kids, too. Children now represent about 9% of all Covid-19 cases in the U.S., up from 2% in March, according to the most recent weekly report issued from Children’s Hospital Association and the American Academy of Pediatrics. The number of child Covid-19 cases has doubled since July 9, totaling 406,109 as of Aug. 13, according to cases reported from 49 states. The majority of children experience mild illness or even no symptoms from Covid-19, doctors say. But some are reporting symptoms that persist for weeks, or the development of post-viral syndromes. Symptoms reported include fever, cough, headaches, shortness of breath and gastrointestinal problems. Matthew Kelly, an assistant professor of pediatric infectious diseases at Duke University Medical Center, oversees a registry of more than 400 children in North Carolina who tested positive for Covid or who had a close contact test positive. And while most teens had symptoms that resolved in a week, 25% still reported symptoms after 12 days, and 10% still had symptoms after 17 days, such as cough, fever and shortness of breath.https://www.wsj.com/articles/as-child-covid-cases-rise-doctors-watch-for-potential-long-term-effects-11598289636?mod=hp_featst_pos3  source
