I’m sorry about your mom. What exposure to Covid did you have? Did you care for or enter the room if an infected patient without appropriate gear ? If not you were not exposed and there are dozens of reasons to have cold symptoms circulating right now
There was a Corona patient in the next room, and the door to the room was not always closed when I walked by. Regardless ... I was sicker than a dog for 3 days, and they kicked me out of the hospital because they did not want me to get anyone sick, but would not test me.
