See this Washington Post article, Desperate for medical equipment, states encounter a beleaguered national stockpile.
When will there be enough equipment for everyone? I'm guessing later this summer, into next fall. Shortages will persist especially in the short term, weeks and months. The good news is supplies will be available if the virus takes a break during the summer (still not known) and comes back when colder weather returns.
2020 is shaping up to be a very interesting year. What if the virus does fade in warmer temps, but "moves around" and then when temperatures cool, hits those areas, such as those not being impacted now, rural areas?
2020 is absolutely going to be in all the record books, in one way or another.
