Second bout of Covid

[ilovebagpuss]

Just looking for some boffins opinions please. Was Ill in April not testing at that point get antibody test July good positive antibodies great had it etc.
Tested regularly at work get positive test this week I’m isolating etc feel fine. Is it a false positive? Old cells ? What the Jeff is going on? Or have I genuinely got it again? Anyone have any insight?

Don’t they say antibodies may only last a few months? I could be wrong though....

any chance of getting another test? This would help rule out a false positive

there have been a few reports of people getting covid-19 more than once.
'lucky' you, op

There are different strains apparently. I read about a man in the states who had it twice and was poorly both times but most people with 2 separate infections seem to be asymptomatic the next time

You could have 'caught' it again but this time you have some immunity so the virus hasn't been able to replicate to make you ill. My understanding of the reports of people who have 'got' it twice is they've had a positive test but not necessarily actually had symptoms (but I may not be up to date).

Thank you it is a while since I had the antibody test (Jul) and as I am in a work environment where it is around it’s possible I have just got some virus again. Feel a bit like I have a cold today but otherwise fine.

Possibly a false positive. Estimate is 0.8-4% false positives, so at 300k test a day you'd expect at least 2,400 false positives a day.

Possibly by chance it amplified some old RNA left over from the infection that the body hadn't cleared out.

Or finally you could have a re-infection, albeit this time a lot milder because you have protection now. This is the same as if you had a flu vaccination. Any influenza infection will likely be milder and shorter, but there will be some replication.

There’s several people on Twitter I’ve seen had it twice, one under Consultant care so not just thinking they’ve had it twice.

Have an extended family member had it twice too. 5 months apart. Reinfections are likely to become common imo in fitting with other circulating Coronaviruses.
