How fast or slow does the virus evolve towards lower mortality? If you get infected months later, is it still essentially the same virus, or a less aggressive strain?
Given the 2-3 week transmissible incubation period where the infected show no symptoms, it doesn't seem like there's short enough feedback loop for the lethality to be tempered through natural selection within the initial period of the outbreak (which we're just beginning).
>Given the 2-3 week transmissible incubation period
No one knows if it's transmissible during the entire incubation period. It's almost certainly not given how other viruses behave. Also the possibility of transmission during asymptomatic periods doesn't mean that it's likely, or that most transmissions happen during that time.
