Me and my husband tested positive for covid at the end of last week. 3 out of 4 of my kids have become I'll in the last few days but all testing negative for covid. Im confused of how this could be. Regrettably me and my husband haven't been wearing masks at home and it's very possible the kids could have caught covid from us. Worried I'm not testing the well enough or something. We are supposed to be seeing my parents as soon as isolation is over but my dad is high risk. Really worried the kids are positive but we will think they are negative. How likely is it that they have become I'll will normal colds and not covid?
