re: German Study: 34% of healthy individuals may have a different type of immunity to COVID

It apparently is 20% identical to measles and 29% identical to rubella. Thoughts?

That this is a meaningless statement by itself.

What you need is an antigen which is very similar.

Not overall genetic similarly. Biochemistry tends to be very very conserved, and as a result the immune system is very very specific.

Cross immunity typically happens because of an overlap of a single surface protein.

Pretty genius virus China created. Got to give them props

Came out of the Wuhan wet market baw. Just like in the movies.

I agree. The MMR angle is probably the least compelling argument for the age disparity.

However I believe this T cell immunity issue is the biggest news I’ve heard in awhile. It’s a shame most people chose to focus on silliness like this video of the woman claiming Fauci is running a coverup

It’s very strange that a contagious virus only has a 15% chance to infect others in the house

---

Yes it is, just from wife’s coworkers and sister and niece contracting it at hospital, 4 carriers have only infected 2 in their respective households that we know of to this point. So that falls pretty close to the 15%.

This means that POTENTIALLY there could be a large percentage of people that are naturally immune to the virus due to previous infections with other coronaviruses. (FYI kids pass around a lot of coronaviruses.)

---

I know a few teachers who have had COVID-19. All four were mild cases. That’d probably be a good target population to test this theory on given the viral load we experience with sick kids in a school setting (especially October-February).

I’ve always been curious what kind of immunity I’ve built up over the years working with snot nosed middle and high schoolers for a decade. Since I’ve been in we’ve had H1N1 and the re-emergence of Whooping Cough and Measles. And everything else you typically come across with kids.

I love watching a bunch of people talk themselves into “evidence “ of whatever it is they want to believe. It’s entertaining. Sad, but entertaining nonetheless.

I agree. I'm still thinking that the very low #'s in the west coast (california with less than 2000 deaths) leads me to believe that this was spread slowly in the fall in the west coast.

---

It's likely 2 different strains

The virus mutated and the NE is probably infected with the Euro version of the virus and the west coast is predominantly more the original Wuhan one

How's your hosses Haskins and Lawrence doin

The only information to counter that is the 192 of the 195 inmates in that LA woman's prison that tested positive.

Although, since that's the only situation that's come up where tight quarters extended contact has brought the %positives even above 50%, it seems equally likely to me that all the tests were done using the same contaminated or mis-calibrated instrument.

Other explanations: Demographic and historical behavioral distribution of prison tends to not be the same as general population. For instance, if extended drug use has some impact on susceptibility.

I agree looking at if from the outside, there has to be something limiting susceptibility to this virus in many people. Nothing else would explain how you can simultaneously infect several people at a restaurant while not infecting people that live with you. Also, as easily as this curve bent (Even in NYC) it seems like it would reach asymptotic behavior well short of N = (1-1/Ro)% of the population.

Yea its a good point. But jails and nursing homes don't interact with very many people. They may have less exposure to other coronaviruses.

Exactly. Almost all curves are bending at the same point and time.

Are we to believe different countries are practicing the exact same social distancing, or is it more likely that there is some external factor we don't know about?
