Fascinating stuff really.
“fitter” doesn’t necessarily mean more lethal. In fact, there is pretty good evidence that many pathogens have become less lethal over time allowing infectious people to survive longer to infect other people. Cholera back in Elizabethan times was far more lethal than it is today. The El Tor mutation let people live longer and spread cholera longer.
