If there are flights; is the US applying quarantine to inbound visitors? I ask only because I was looking to go to NZ as I am currently sans work and have a UK and NZ passport so thought I could sneak in for a family visit - a 14 day quarantine applies in NZ though the airlines don't mention it and apparently its been a bit shaky in terms of enforcement which is why, after weeks of no new cases, NZ has people testing positive again.
When will we be normal again?
I think 'normal' is when the annual flu jab includes 2019-nCoV and there is an uptake of at least 50% (seems there is still debate re the R0 of this virus so the classic formula for the herd immunity threshold of 1?1/R0 gives differing opinions for the minimum population that needs to be vaccinated). For comparison measles requires an 83 - 94% uptake for herd immunity (highly contagious, R0 of 12 - 18).
Remember H1N1 (the swine flu pandemic ca. 2009) - that is in the annual flu jab so it isn't talked about anymore. That virus probably came from wet meat markets too!
Technically a vaccine was developed for the first SARS outbreak (2002 iirc) but for some reason I don't think it ever went into production - whether it was a fail or whether that iteration of SARS just didn't re-emerge diminishing the commercial viability I don't know. An Oxford research team where involved in a SARS vaccine so they were saying they have a jump on this virus but I haven't heard much from them in the media lately....
Given the gazillions of $ being thrown at vaccine research via many different routes (pharma, coalition funding, philanthropy etc.) for this sucker we have to hope that one or more lead candidates are identified soon, proven to provide protection, and distributed as open source for production facilities around the world to ramp up.
Everywhere that has relaxed social distancing seems to be seeing flareups; target is to keep R0 below 1 - essentially a physical rather than biochemical form of herd immunity: stay apart, don't transmit it.
I reckon doing a couple of hundred mph at the quarter would satisfy social distancing; I wish I could be there this year
