I suspect that it will be well into next year before a reliable vaccine or treatment is found for this virus. In the interim, there may be several "cures" announced that will either be of little value, or have serious side effects. People will need to recognize the seriousness of this virus, and continue to practice "social distancing", etc., for many more months.
I fully expect the numbers to go down in coming weeks, and people will relax their vigilance, which could easily result in a resurgence that is equal to, or even greater, than what we have been seeing.
Insofar as the economy is concerned, I see continued high unemployment, sporadic shortages of basic items, and a Very Good possibility that we could sink into a recession similar to the early 1930's.
