A friend of mine tested positive for C19 back in April. He’s genuinely stumped as to where he got it. Said he’d zero contact with anyone bar his family, none of whom “were sick”.
He said he went for a run one day and swung by the shop in the way home to pickup milk, and reckons he contracted it there.
I reckoned he got it from one of his kids, aged 8 and 11, I think.
Anyway, he’s made an appointment with his doctor for the entire family to get antibody tests. He’s determined to either rule them in or out. But chances are, if he did get it from them, and they were asymptomatic, they won’t have the antibodies anyway.
