Soooooo my mom has Covid. My aunt & uncle, who she lives with, also have Covid. But they seem to have caught it from different sources, because my mom got it on vacation, started feeling symptoms on the plane home, and isolated as soon as she got in the house, while my aunt felt sick 2 days later. From what I hear, the incubation is about 5 days, right? Oh, and my uncle tested positive yesterday but didn't feel any symptoms until today. This strain is weird.
