如何看待美国新冠疫情确诊人数突破六千万？ 第1页

即使以每天200万感染数量，如果按照70%群体免疫的话，再增加1,5亿感染者比较可靠，那么就还需要继续努力2个半月。然后美国人就可以彻底轻松了， 所谓得病一身轻，

不要觉得这是纯粹在反讽哈， 现在的奥密克戎被认为主要是一个上呼吸道病毒，而不再是一个重点造成肺炎的病毒，且症状轻微，而感染了这种病毒后对其它如德尔塔毒株等反而有很好的免疫效果。因此基本相当于一个副作用比较大的疫苗。以现在的重症率不可能击穿美国的医疗系统。

所以现在很多国家预测今年将随着奥密克戎的大流行而结束疫情。不过这也要看其它还会不会有新的更具杀伤力的毒株出现

Notes from a call with Edward Ryan MD, Director of International Infectious Disease at Massachusetts General Hospital:

1 Close to 100% of the positive cases in MA are Omicron. Delta is almost completely gone from New England.
2 This surge will peak sometime between 1/10 and 1/21 and then begin a quick downhill journey of two to four weeks.
3 We will end up with a 20-50% positivity rate.
4 February will be clean up mode, March will begin to return to "normal"
5 Omicron lives in your nose and upper respiratory area which is what makes it so contagious. It isn't able to bond with your lungs like the other variants.
6 The increased hospitalizations should be taken with a grain of salt as most of them are secondary admissions (i.e. people coming in for surgery, broken bones, etc. who are tested for COVID)
7 We won't need a booster for omicron because they wouldn't be able to develop one before it's completely gone and we're all going to get it which will give us the immunity we need to get through it.
8 COVID will join the 4 other coronaviruses we deal with that cause the common cold, upper respiratory infections, RSV, etc. It will become a pediatric disease mainly affecting young children with no immunity.
9 40% of those infected will be asymptomatic
10 Rapid tests are 50-80% sensitive to those with symptoms, only 30-60% sensitive to those without symptoms
11 Contact tracing is worthless because we're all going to get it and there's no way we could keep up with it.
12 We are fighting the last war with COVID and should be pivoting back to normal life, but society isn't quite ready for it yet.
13 There is no need to stay home from work or to be a hermit unless you're immunocompromised or 85 or older, but he does recommend staying away from large gatherings for the next six weeks.
14 Spring/Summer will be really nice!

Overall a great presentation. Lot of good news.
