> it is likely we'll have an available and effective drug for treating it
I don't believe this is likely at all. At best we will have something that kinda sorta works in some patients. If this was likely we'd have a drug for the common flu long time ago. To remind you, the flu takes about 50K lives in the US every year.
There are effective drugs for common flu strains; including a set of vaccines. And if the US manages to get COVID-19 related deaths down to 50k lives for 2020 that will be pretty peachy.
There won't be a vaccine this year. That's pretty clear. Vaccines take a long time to get tested under the best of circumstances. If not tested properly and administered to millions of people (which they'd have to be in order to have effect) they could cause a lot of adverse reactions and deaths all on their own. Don't take this as antivax bullshit: I do take a flu vaccine every year myself, including this year, my kid is fully vaccinated also (+ flu vaccine last year - I told him to "be a man"). It's just the nature of the beast - immune system can really fuck one up once it really gets going.
1) Such an individual would be contracting an unknown virus in an environment where hospital staff are the least prepared and practiced at dealing with it.
2) Such an individual is still exposing themselves to high risk of mistiming the outbreak and hitting it at the peak.
3) They might accidentally catch a different disease thinking it is COVID. Then if they got COVID they'd have 2 diseases; which is probably going to be quite bad.
If we all avoid getting COVID-19 for, say, another 2 months it is likely we'll have an available and effective drug for treating it. There are something like 5 different candidates I've heard of, so even if the odds of any individual one working out are <30% there is still a good chance there will be effective treatment by mid year. The contain, delay and avoid strategy really is a better bet.
