Covid question from others experience. I tested positive to covid yesterday. My sons have been sick off school the past week- 2, similar symptoms as me but both have had covid previously. This is my first time covid positive. My sons rat tests have been negative over the past 1-2 weeks, while they have been sick. Mine showed up within seconds positive. Do you think it’s possible that they could have been positive, hence why I got it but not showing because they have had it previously? Is this just my theory?
