Past Covid-19 infection may provide 'months of immunity'

[AtW]

“Most people who have had Covid-19 are protected from catching it again for at least five months, a study led by Public Health England shows.

Past infection was linked to an 83% lower risk of getting the virus, compared with those who had never had Covid-19, scientists found.

But experts warn some people do catch Covid-19 again - and can infect others.

And officials stress people should follow the stay-at-home rules - whether or not they have had the virus.”

83% is interesting figure, but if it was that low we’d have a lot more reports by now with re-infected people - been 9 months since plenty of infections in the UK.

Mybe just maybe immunity from Covid lasts much longer (not the same as still getting virus and passing it on)

Some people are claiming they have been reinfected as in late 2020/around now as they have had the same symptoms as in early 2020 but they couldn't get a test then but now they have tested positive.

Some people claim all sort of things

No proof== no valid claim

Yeah I enjoy telling them -

I do know a couple of people who have had Covid but didn't know. They have had antibody tests. They are freaked out by it as they could have infected a fair few people.

That I believe - asymptomatic spread is one big reason Sars2 was so successful (in virus terms)

Exactly, which directly contradicts this point:

We have no real idea how many people are getting reinfected, because it requires a proper test during both infections - neither of which is likely, especially first wave, when a very small percentage actually tested +ve. This effect could be compounded if the second infection is much milder than the first, due to some residual immunity - but you might still be able to spread it the second time around.

That figure comes from actual study (hint: it involved tests) -

“ From June to November 2020, almost 21,000 healthcare workers across the UK were regularly tested to see whether they:
currently had the coronavirus
had had it previously”

That, and the low mortality figure, and especially the fact that risk of death was to tightly confined to a specific demograpphic. If this thing was killing 10% (SARS1) or 30% (MERS) across the board, we would have shut our borders and never have come out of the first lockdown until it had been eradicated.

OK, well that actually is quite interesting. 83% after 9 months doesn't sound too spectacular to me, though.

Low mortality? With all the lockdowns UK got biggest loss since WW2 -

Moot point anyway - people who run countries are old, so this virus is taken seriously (unlike swine flu pandemic which mostly affected young)
