I think my daughter and I had it in March (we were sick the week before isolation started in our province... I'm in Ontario, Canada.) There were confirmed cases from travel in our area at the time. We found out later that more than half my daughter's class was off sick that week... out of a class of 22 or 23, there were 8 kids present one day!
Anyhow, my 13-year-old started first, woke up with a high fever, bad cough, skin pain, body aches, chills, sweats, headache, fatigue, swollen glands, and eventually congestion. We saw the doctor but they wouldn't test her for COVID-19, as at that time they were only testing people with travel history of known infectious contacts. They just said she had a viral respiratory illness but no pneumonia and to take her to the hospital if she had trouble breathing. A couple of days later I started with symptoms... I had a fever around 102, a hacking cough that felt like I was going to actually rip something in my throat, chest tightness, the worst swollen glands of my life, chills, sweats, fatigue, bone aches and pain, skin pain, and finally congestion. It lasted about 7 to 10 days for both of us, and then we still had lingering annoying cough after that. We tried to avoid the rest of the family, my husband seemed fine and my other kids had a really mild sore throat/cold around the same time, but didn't get really sick.
Long story short, I don't know if we had COVID-19 (could have been the flu), but given what I've read about symptoms and the fact that it was confirmed to be in our area, I think it's very possible. I really wish we could have been tested and if an antibody test becomes available I would be interested in taking one to see whether I did have COVID-19 or whether it was the flu.
