1st DC tested positive on Friday last week, last contact with a positive case the Monday before.
2 further DCs tested positive on Sunday. Me, DH and 1 DC were negative.
The three of us who were negative retested yesterday and again negative despite having mild cold symptoms! Similarly positive DDs boyfriend also tested negative.
How? We’ve all been isolating since last Friday. Not really able to isolate individually and as I assumed we’d all have got it anyway when 1st DC tested positive, we haven’t been making efforts to sanitise door handles etc. House isn’t big. They are in and out of their rooms, in the kitchen, share a bathroom.
DH and I were extremely ill with a mysterious illness in February. It was flu like but not ‘flu’. I had a cough for 3 months afterwards. Negative DC was also unusually ill (in bed practically unconscious for two days), two of the positive DCs had temps and coughs but mildly. DD’s boyfriend was really ill with high temp and cough on the summer but he never got tested (he wasn’t with DD then).
Is it possible that was CV and we have antibodies so didn’t get reinfected? I read yesterday that antibodies can last for 6-8 months or longer but the evidence isn’t there yet as CV’s not been around long enough obviously. Apparently only 25 people in 52 million have been found to be ‘reinfected’ so far.
I can’t find much info on whether you would test negative if you had been reinfected but had antibodies.
Anyone know.
