I had a horrible cough that lasted for weeks, so bad I couldn’t even hold a conversation. I think it was C-virus.
I had a couple pay me a visit at work. They looked & sounded horrible.
They both had been hospitalized and were “recovering” but could hardly speak due to their coughing.
This was right after Thanksgiving.
I was sick within a week.
I never had a fever, but it took me 3 weeks to shake that cough.
Seems like it was too early to be Corona - who knows.
Maybe there should be testing of people who were sick with symptoms like those of the C virus and recovered during Jan to March. These tests might show a large group of people who had the virus and have recovered. Maybe they are now immune.
