I see this post was a while ago. I hope you and your family are doing well. I suffer from seasonal allergies, too. But my symptoms are a stuffy nose and sneezing. Not the COVID symptoms. Still, I take my temperature daily.
I hope that you are all able to self-isolate. I don't think there's much danger if you do that. But my fire department has recommended everyone fill out a File of Life card for medical providers. One of the bad things about this disease is nobody can visit you in the hospital. And if you can't talk, this card will give first responders and medical providers the information they need.
