My wife works in health care here in Denver and they're being instructed to keep visiting patients who they suspect may have Covid-19 (without PPE mind you), but those patients haven't been tested. One of her co-workers was exposed to a Covid-19 patient, and is currently running an on and off fever with cough, but she hasn't been tested. Instead, she's in self-quarantine.
Health care professionals are currently running into a lot of "potential" Covid-19 cases, which are more likely the average flu, but they don't know because no one is being tested.
She's also heard from a family member who works in the hospital system in Atlanta that they are on the verge of being overwhelmed.
