Isn't this a bit of promising news, means herd immunity is probably much deeper and larger than we are currently aware.

WHO says we can't assume previous infection means future immunity. https://www.who.int/news-room/commentaries/detail/immunity-p...

You can be reinfected. It sounds like there's already some evidence suggesting that reinfection is at least significantly less likely than initial infection.

No, that can’t be the case here, because a shockingly large proportion of people tested positive according to the article. (Thus, either the false positives are negligible, or the test employed has a an astronomical false positive rate (bad specificity)).

You're right, they get a positive result for almost all the population! Wait, does that pass the smell test? Do prisions become huge flu hotspots as well? The Diamond Princess outbreak didn't have that kind of numbers... What's more likely at this point, the numbers from the article or human error? My respects to anybody trying to do actual science with this kind of data in this kind of situation...

Not quite this huge, but then again states generally try to get them flu vaccines. It's reasonably common for prisons to enact emergency measures to stop the spread of the flu.

I've read that asymptomatic carriers are though to be less infectious than those with symptoms because of the lower concentration of virus in the saliva. Also, many virologists mentioned in recent texts that the initial concentration of the virus you receive can affect how sick you'll get - the more viruses you're exposed to, the faster they can invade the body and the more severe it will get. Can those two facts be…

I have been wondering about the effect of the degree of initial infection. I kind of assume the virus grows exponentially inside the body and would dwarf the initial constant. If a low initial dose affects the severity of the disease, I think that would be incredibly useful to know. I also wish there was info on percentage of infection via fomites vs inhalation.

> I kind of assume the virus grows exponentially inside the body and would dwarf the initial constant.

Perhaps a more mild initial growth stage gives the immune system more time to respond.

There it is! Now can we get back to normal. Of those 4% with symptoms, what tiny percentage need advanced hospitalization? Of that tiny percentage, what tinier percentage still, die?

As a Canadian, I'm shaking my head at our officials who said "we do know that asymptomatic people are not the key driver of epidemics" as a response to concerns back in January of the potential for the virus to grow in our country via incoming travelers who came from hot spots and were not screened or forced to isolate if they expressed no symptoms. Now our long term care facilities are being overrun with cases poten…

A test is a snapshot of time. A person could pass a test and be shedding viruses two days later. A person could shed viruses, get over it, and pass a test.

how do you ever make antibodies if you are perpetually asymptomatic though? do you carry it forever? does it attack eventually? what happens if you are an asymptomatic carrier and get a vax?

"Typhoid Mary" was an asymptomatic carrier of typhoid fever for at least 38 years.

Ultimately this has exposed that WHO is a malicious institution which actively undermines the public health for Tedros Adhanom's personal relationship to the cause of the CCP and of fascism more generally. Each of our government's dangerously false statements has come from the WHO, and trusting them has been the primary mistake made in assessing this threat. "no evidence of Human-to-human spread" when they had eviden…

I can’t believe this is not a new account. Blanket propagandistic statements are not the conversation we have in Hacker News comments.

I've been tracking the antibody study results in a spreadsheet, and they are suggesting a 10-20x undercount of cases in the official "confirmed" numbers. You can see the data I've collected here: https://docs.google.com/spreadsheets/d/16onEUBWIV5IqN1RCvTla...

Your sheet is interesting. Looking at it, the IFR varies from 1.66% down to .11% and the 0.11% is for the Santa Clara, which many considered rather suspect. The 1.66%, otoh, seems reasonably in line or at least compatible with what's been observed in Korea and elsewhere. Given age is going to skew things a good deal, it seems like a picture is emerging but not that new a picture. An IFR of even 1% is pretty bad, espe…

The numbers that are quoted for Austria (which has the listed IFR of 1.66% in the document) weren't obtained via antibody tests, but via PCR tests. Here's a better source than the one linked in the document: https://www.sora.at/uploads/media/Austria_COVID-19_Prevalenc...

Most of those tests were done on April 4th and 5th which was 3 weeks after Austria started relatively strict lockdown measures, which also impacts that number, as this will result in the test to find an even lower number of positive people.

Right, it could literally be as dumb as: all the tests were processed by one person, and that person is infected with covid-19.

Drawing signal out of the noise right now is very, very difficult.

If the virus moves fast through a population (like we might expect in a crowded prison) then all the population in one provision will have a single strain.

However, this is 4 prisons: do staff or inmates move between prisons more often than say every week?

It is possible (although unlikely) the virus strain is less spdangerous.
