I've also found out that PPE shortages are still occuring, just not being covered by major news media (again as far as I know).
Also, there are degrees of risk and many health care workers, by the nature of their work, are far more exposed to the virus than are the rest of us, since they spend so much time in such close contact with people are, or are highly likely to be, highly infectious.
Yes, working in a store or driving an Uber brings you into close contact with many people who may be infectious but working in an hospital or as a paramedic brings you into far closer contact, for much longer, with many people, some of whom most certainly are infectious, and while PPE mitigates the risk, sadly it does not remove it.
Similarly, it seems to me that, as a patient suffering from something other than Covid-19, I'm at far greater risk of infection from a healthcare worker who is carrying the virus than I am from anyone in the supermarket, because we're going to be in far closer contact.
For everyone's sake -- patients' as well as health care staff -- the authorities need to take every care to protect healthcare workers from infection.
