Such as? Post your examples with numbers to support your arguments. I can think of many reasons that might apply.
The need for PPE was massive. Demand and need continues to be high (much of it are consumption items). Just think about the difference between admitting an infectious patient versus someone who is ill but their issues aren't transmitted to everyone around them. Ventilators were in high demand. Better to plan for more rather than find yourself short. Stocks are now better and are able to be redistributed to where they're needed most at any given time. The more difficult issue is planning bed capacity as adding this isn't as easy. A lot of additional bed capacity, some already planned and some not, was accelerated into service - to the extent that hospital finances allowed. Very big disparities here. Then of course there is the issue of having the requisite staff (and, again, why having adequate PPE is so important). Luckily NPI had the desired effect in the most critically affected States with consistent or lessening strain on resources. Need would have undoubtedly been a lot more without the breathing space provided. (Excuse the pun.) But also ICU bed utilization in States like Arizona, California and Florida is rising - unsurprisingly - with rapidly increasing case count. While one day doesn't make a trend, Florida today announced its second worse death count. (Arizona hit a record also.) Like I said, it's going to be interesting mostly because a belligerent population is unlikely to be sympathetic to renewed restrictions if hospital capacity is reached. We've just got to keep 'processing' the population through the virus, with its pruning - particularly - of over 60 year olds, until we get a vaccine in a year or so. Onwards!
