- selectodude 4mo agoAnd there’s a non-zero chance that it lives dormant in your brain and you die several years later. Absolutely bonkers.
- throwa356262 4mo agoWait, measles erases antibody memory? First of all, this is scary. Secondly, I wonder if it hase the same effect on autoimmune disease?
- mrtesthah 4mo agoMeasles infections can trigger the following autoimmune diseases: * Type 1 diabetes * Multiple sclerosis * Rheumatoid arthritis
- madaxe_again 4mo agoIt can. It’s not common, from what I understand, but there are cases where it has put various autoimmune disorders into remission, either temporary, or permanent. That said, you become far more likely to end up sick with a whole bunch of other stuff, which can then eliminate any benefits for the autoimmune disorders. Oh, and there’s also a chance it will give you an autoimmune disorder. Absolute bastard, if you ask me.

"Once the measles virus contacts the mucosa lining the respiratory tract, it binds to SLAM (signaling lymphocyte activation molecule, also known as CD150) on the surface of macrophages and dendritic cells. These cells then take up the virus... These immune cells pass the virus on to other groups of immune cells, including B cells, T cells, thymocytes, and hematopoietic stem cells, which disseminate the virus to other organs during the incubation period. "Immune amnesia "The measles virus can deplete previously acquired immune memory by killing cells that make antibodies, and thus weakens the immune system, which can cause deaths from other diseases. Suppression of the immune system by measles lasts about two years and has been epidemiologically implicated in an increase in childhood mortality from other infectious diseases during this period. The measles vaccine contains an attenuated strain of the virus which does not deplete immune memory." https://en.wikipedia.org/wiki/Measles https://en.wikipedia.org/wiki/Measles
- alfiedotwtf 4mo agoIt’s crazy that in the past year, I’ve been hearing MAGA hold measles parties yikes!
- guilhas 4mo agoSuch a serious effect I would expect tons of research on it. And being commonly known But it is a seemingly new symptom being attributed to measles Between that and doctors refusing to diagnose long covid or lyme disease. Which have a much bigger link to immune disorders One would think someone is trying to muddy the waters. Or accidentally misattributing
- flawn 4mo agoWhat is the evolutionary advantage of this? I mean, if the host dies subsequently that's pretty bad for both parties, or?
- fhdkweig 4mo agoIf it can spread before killing the host, it has done its job (evolutionarily speaking).
- californical 4mo agoSometimes, even usually, evolution finds a “local maximum” of effectiveness. Where the solution an organism finds is not optimal but it’s good enough for the organism to survive, even win. So yeah I’m sure evolution didn’t create something perfect in the disease here but it survives long enough, and kills few-enough people slowly enough in the wild to survive
- cjmcqueen 4mo agoViruses don't care if the host dies. Evolution doesn't explain all things in nature.

- lightbulbish 4mo agoEvolution theory by itself doesn’t give us the ability to explain everything in a certain moment, but that’s only due to lack of knowledge on our part. Consider that measles in itself comes originally from a animal but a mutation found itself be able to spread to humans. That, in and of itself, is the process of evolution. So while it is not necessarily a useful lens to try to interpret a moment in time as many unknown factors are at play (for example the same gene that is important for mortality might also impact survival in certain environments, and therefore how contagious it could be), if we were to understand it’s history of every mutation that came and went, the environments it lived in, evolution theory would explain why the path looked like it did. And subsequently why it is like it is today.
- bryanlarsen 4mo agoAnd by "it" you mean measles? Or do you mean the vaccine? Completely reverses the message of your post!
- WarOnPrivacy 4mo ago> And by "it" you mean measles? Yes. They mean that measles "erases immune memory, taking away antibodies to recently exposed diseases.". The grandparent was discussing their measles experience and the parent was responding to that.
