copy过来，今天早上刚看到的 Children in China infected with novel coronavirus showed less severe symptoms than adults, though infants and toddlers were vulnerable to moderate and severe infection, according to a new study published online in the medical journal Pediatrics on Monday. The study examined 731 confirmed and 1,412 suspected cases of COVID-19 in children. Out of the combined 2,143 cases, one child, a 14-year-old boy, died and nearly 6% of cases were severe, compared with 18.5% of adults experiencing severe symptoms. Young children, particularly infants, were vulnerable to COVID-19 infection, the authors of the study said. Nearly 11% of cases were severe and critical for infants less than 1 year old. More than 90% of all pediatric patients were asymptomatic, showing mild or common forms of illness. About 13% of patients who tested positive for the virus did not show symptoms of illness. Researchers remain unsure why children with COVID-19 were not as ill as adults.

避免误会加两句：注意没有确诊，在测试是不是COVID19，结果还没出来。上周住院两天，discharge，过了两天忽然就不行了。
谢谢有人跟贴说查出来是阴性。见下面链接。
谁说的？基于中国的数据吗？谁敢信呢？
小孩感染的少是因为他们假期接触的人比较单纯，但是小孩感染后重症的少，应该还是跟年龄/免疫系统有关的
是的。所以我还是有一点点支持这个病毒是ade的观点的。
刚出生的毛娃，还没来得及打任何疫苗，什么都不用管，自己就好了。
人年龄越大，体内的各种抗体越多，事儿越麻烦。
这是从中国的数据得出的结论。但是想想中国的小孩子那个时候放假的放假，呆家的呆家，小孩冬天很少出门怕着凉，本来就没有什么传染机会。中国daycare也极少，多半是自己在家带。
我很怀疑这个结论能extrapolate到世界其他地方。
不会看韩国数据？
韩国至今感染8000多人，其中30岁以下无一例死亡。
还有个原因是国内养娃多精细啊，稍有风吹草动全家人都如临大敌，估计也都发现得早，我觉得啊
An Italian doctor talked about similar observation on British tv. Kids' critical case rate is low.
大家都说的是低风险，概率懂不懂？个例能拿来说事吗？
中国数据不可信，那就看韩国、日本、新加坡、意大利的喽，看看年轻人还有孩子的死亡率是多少，看是不是这么回事呗，这些国家的数据不都显现小孩子基本没有死亡的吗？
婴儿是可能有较大风险的，需要特别照料，国内的例子也有。4、5岁以上风险就不大了。
是的，infants toddlers 还是风险大的。
中国数据婴幼儿重症率也不是很低的，真正低是学龄儿童。 很多人都只听传闻，不看data，不看原始报告， 想什么信什么。
多谢，看来有宝宝的还是要小心。
那个后来证实是谣言， 孩子是煤气中毒走的。。。。
意大利死亡90%以上是七十岁以上老人。但这只是说相对老人，年轻人安全的几率高些，不等于小孩就完全没事啊。
本来也没说小孩患病率低啊
说的是小孩确诊的里面重症率低，这个到底有没有道理
以讹传讹
我们医院有确诊的孩子了。babysitter传的。
美女，能过几天update一下情况？孩子到底是不是比较容易痊愈
ACE2受体有没有什么varaint相关? 可以看看测序数据
