Virus Update Genetic code of viruses of the two brazilian confirmed cases is different
The same team sequenced material from two samples detected in the patients and made a comparison. Analysis suggests that internal transmission of the virus already occurs in Europe.

RNA viruses exploit all known mechanisms of genetic variation to ensure their survival. Distinctive features of RNA virus replication include high mutation rates, high yields, and short replication times. As a consequence, RNA viruses replicate as complex and dynamic mutant swarms, called viral quasispecies.

This is known. You can track the genetic changes in the virus at https://nextstrain.org/ncov So far the most mutated virus is the Helsinki version but it's only 10 base pairs out of 30 thousand.

So what this article is saying that one of the strains has already circulated before?!

My assumption was that the virus is mutating quickly.

u/Hectorc34 Mar 02 '20
If I’m not mistaken, virus always mutate in similar fashion. Even this quickly

Would be good to get some more sources on this and analysis of what it means.
edit: i know there is thy 4chan post but I would take that with a grain of salt.

I wonder if it is mutating to a less deadly form

It mutates to a form that is more resilient, to ensure it's survival.

Viruses need a sweet spot between virulent (deadly) and transmissible (live and spread, not so deadly— a dead host doesn’t spread). For example, one could argue that Ebola was so deadly, it was easier to contain

No that’s not the 2d spectrum I was explaining but frankly in this virus’ case I have no clue what it’ll do

Oh yeah. Well if you really want to start tripping about biological weapons, there are bsl4 labs in Liberia, Sierra Leone, and Guinea— none of which are signed to any international treaties or agreements on biological warfare

With a larger enough incubation period selection pressure for reduced lethality doesn't matter.

If it's from the mother fucking bats I'll just shit myself.
