Funny thing the county emt whose ambulance took me to ER when I had a bad shortness of breath attack combined with falling average spo2 asked ne what was wrong. I told him I had trouble getting air , dropping avg spo2 and had covid. He said no reason then to take you to hospital because there is no treatment fir Covid, but if want I will take you.
Luckily my spo2 stabilized and shortness of breath ended temporarily by the tine I got to ER. Since spo2 stabilized at 92 they just treated dehydration, lack of salts in blood, etc. Covid with bronchitis. Few hours later allowed to go home, so avoided hospital stay. Still amazed at EMT saying there is no known treatment for Covid. But he is just an emt.
