I just found out that my wife and 3 kids. 7yr 5 yr

I just found out that my wife and 3 kids. 7yr 5 yrs and 5mos and myself were all exposed to it or even had it. My wife and her friend would take turns everyday bringing the kids to school and even going to each others birthday parties. She has 3 kids as well.We all got a little bug of some sort for about a week or 2 right around christmas and after christmas break. We kept our kids home on and off during that time. The friend though has been pretty sick since then and has been insisting on being tested but they wouldn't do it they just did a lung xray last week and said it must be something else. She finally went to the er yesterday and they found that she is in the final stages of recovering from covid 19. She did have underlying issues and it looks like she will be okay. So between the 2 families that's about 10 people who continued to go to school and work for a while after. There have been no cases of anyone else connected to her being affected. I think it's pretty dangerous for some but most just develop an antibody. Sorry for the rambling. Everybody be safe.
