We have a few neighbors who have had Covid on my street. I live in an "Active adult" community here in NJ. One guy and his wife 3 doors up were just tested a few days ago prior to their kids coming over for Christmas, and he tested positive, so he and his wife are in quarantine. He has absolutely zero symptoms; they were amazed he tested positive. His wife tested negative.
Further up the street, another guy was tested at work; he works for the Township. He too tested positive, while his partner tested negative. She lives in the same house with him and also works for the Township. The guy also has had zero symptoms, and he has gone back to work just this week.
Another few doors up, a husband and wife both tested positive. They have had a mild set of symptoms, basically flu-like.
One street over a man got Covid, and he passed away from it.
Amazing just how varied this thing is.
