> what nobody wants is it to remain viable and continue to mutate into something that ISN'T 99% survivable. That's not how mutation and evolution of diseases work. You have played waay too much pandemic. 1. A mutation of a virus doesn't instantly spread to the whole population as in that game. Virii cannot communicate wirelessly (duh) and update their RNA on the fly (double duh). ANY new mutation must spread on its own ALL OVER again. 2. Mutations that make diseases more deadly tend NOT to spread because the infected will be lying down sick or dying instead of socializing. MILDER forms of the disease are FAR more likely to spread. 3. The combination of 1 and 2 is what turned the Wuhan flu bioweapon largely harmless by the time it reached wider China and the outside world. It is also why dangerous diseases (when not engineered by the CCP/USSA) generally come from other species. When this happens the disease may be dangerous because it is adapted to be harmless to THAT species and not humans. However, after a while such diseases adapt to humans and turn harmless. This is also RARE because jumping species is hard and unlikely, basic hygiene and not living too closely with farm animals and wildlife largely eliminates the risk.
