YMCA一直有center开着
昨天7月12日新闻， NBC 采访了5位儿童医生 pediatricians，东西岸都有， 5位医生一致认为 reopening school 没问题， 说绝大多数的传播发生在成人和成人之间，或者成人传染孩子。孩子传染大人的情况很少。 最年轻相对貌美的白人女医生说她都觉得小学生戴口罩没什么用。 （意思不需要戴。）

希望有人能针对这个做一些深入的研究。 如果孩子的低感染率能达成共识，那真是太好了
Makes sense. 小孩不像大人，戴口罩戴不住。
Like what happens in every flu season?
也许这些孩子免疫力更好点，因为可能家长或多或少带点病毒回家。长期少量低浓度接触病毒，还有可能刺激免疫系统增加抵抗力？不是有说法太干净容易得病，不干不净吃了没病？嗯，我瞎说的
如果真的有广泛认可的结果出来，那一些州一些地区先试点，然后逐步推开。
给愿意回学校的老师鼓掌 公校的老师没有任何动力回学校上课，工资不变，网课他们每天工作量绝不超过一小时。真的是要很有觉悟的和责任感的教育者才会支持开学校
确诊少的州安全。
确诊多的州TX FL 南加之类的不安全
1000+个center只有4w学生，平均一个center不到40人，这跟reopen后不是一个数量级的
坐标中部，家附近的daycare一直开着的，今年没关门过。双职工家庭的孩子得有人带啊。有个中国同事的两个孩子一直在送，家里没老人帮忙。
跟3月份Surgeon General信誓旦旦的说戴口罩完全没用还有害一模一样
"This has been a strange pandemic because usually for respiratory viruses, children are the first and most substantially affected,"
这个事情的确很难搞大study 不过其他不少国家开学走在美国前面 可以静观其变看看人家的经验
有的地方开学没爆发 有的爆发了 比如以色列好像搞砸了
可以吸取经验嘛 毕竟新病毒 拿原来flu的直接套过来不合适
是的 小朋友和高中生区别挺大的 其实大家觉得小朋友风险特别小指的是小学生
高中生和二三十岁的其实差距不大 风险比小孩大一点但是仍然很低
我怎么记得flu season都是强烈建议小朋友要打疫苗？ 因为属于脆弱的人群。 为什么到了新冠就是最不易感的人群， 感觉不太合理啊
这个靠谱， 没有说明是在哪几个州采样。 初期很多州没有什么病例的。
我们娃的daycare一直开着，只有一个小娃感染

理解需要送学校的家庭，也理解坚决不送的，自由选择就好，没必要说服别人，我朋友圈已经有很多人开始party开始聚餐，我理解，但是绝不会参与，同样，秋冬不管怎样都不会送小孩去学校。
是的，这个是旧闻了，现在德州自己的daycare就有1900多case，其中650个小孩。老师确实比例更大，有些老师已经住院了。 https://www.fox4news.com/news/parents-concerned-as-covid-19-cases-surge-at-childcare-centers
YMCA的summer camp也有爆发，👇🏼这个camp一家就有85个确诊的 https://www.kiro7.com/news/trending/85-campers-staff-test-positive-covid-19-ymca-summer-camp/OPSPVDSXRFCLZOD7SEMLCYN2OA/
不讨论小娃传不传大人的问题。
单纯说，你的逻辑水平绝了。儿医关门能推导出小娃不传大人是扯淡？他开门又不只看小娃，娃爹妈也在娃边上呀。
我也有好消息， 中国复学至今还没有小孩感染！ 不说当地有多少感染的， 等于啥都没说！！
是的，我家朋友的一岁的孩子一直在day care。
几个州的re-open事实上失败了，股市都受波动。病毒面前，光有信心和勇气是不够的。
我就是公立高中老师，说实话，我不愿意回去，因为我自己本身就属于高危感染人群，我觉得没有任何东西值得用生命冒险。还有，您教过网课吗？如果没有教过，您是怎么知道每天工作量不超过一个小时的？很多东西除非亲身经历过，否则可能真的不了解其中的真实情况。我们从三月中旬开始教网课，我可以很负责任地说，绝对绝对不可能不超过一个小时。
不会不超过一小时吧。网课也是要教几个班不会把所有学生放在一个班里吧
错，"my life matters, yours don't."
就是碰运气靠侥幸。 小孩子戴口罩戴不住。
你这样有条件的可以不去，才能让essential worker family 小班教学啊
说的就跟学校开了，就要强制你家孩子进集中营似的。
那那个几个月插呼吸管的小baby 是怎么回事？在说现在是老师工会不让开学。
