The 5 minutes of news I accidentally watched earlier was nothing short of the world is falling due to the coronavirus, but what you won't hear is this "southern wave", or whatever you want to call it, has pretty much peaked and is on the decline now in most areas. Those that haven't peaked yet (mainly Alabama/Mississippi, and perhaps Louisiana) will peak this week.
Not sure if it is true herd immunity or whatever it is, but this thing has behaved exactly the same wherever it has gone. Hospitalizations start surging, and in about 50 days they peak. It stays near that for a week or so, then starts to quickly decline. By September the south is going to be in a quick decline all over, and past whatever you consider this current wave.
I have friends in healthcare and we chatted about this. We have some thoughts.
1) There is a lot of data to suggest that the infection rate is underreported. By how much is a debate, but my suspicions are that it is wildly underreported - to the tune of 10x or more.
2) The states seeing a “wave” right now are areas that weren’t as hard hit in the spring. NYC and others contribute to have a lower infection rate. Partly due to opening more slowly, but when coupling their known infection rate with what I outlined in #1 above, they could be slower due to herd immunity taking hold as well.
3) The southern wave could be slowing because at 10 weeks into reopening, we are reaching the plateau that every other population sees at this time.
4) Most things should be reopened with precautions- masks, fewer people and some spacing. It is likely overkill, but we don’t have enough solid data to know what the true minimum is right now. However, life does have to go on, we can’t all stay holed up at home for a year and work has to get done for society to function.
5) Sports and large events (unfortunately) may be the one casualty until we have a better handle on this thing. The data is too unreliable to plan otherwise. I hate it too because we need some sports and entertainment to give people an outlet besides destroying cities.
6) Good progress on vaccines. Modera started a 30,000+ person trial today. Pfizer and J&J have better distribution systems and are making progress on their own. Net- could have multiple vaccine candidates, key will be timely production and distribution.
7) 30% immunity is the key point where the infection rate slows. 60% is where we near herd immunity and this thing becomes incidental.
