Personal note- my college age son had all the symptoms but couldn't get tested because he wasn't in a risk group; in fact the local health district told him he could re-enter society 24 hours after his last symptom-free day (he works in a grocery store). A brother-in-law suffering from the flu waited until he was coughing up blood before going to the ER- where he was diagnosed with COVID19 but not tested because he wasn't a particular risk group. His wife, who shows no symptoms, was denied time off because she wasn't sick and her husband hadn't been tested positive- she works in a nursing home!
