@QueefDr @2PupsMommy @LuigiCavalliBal @DrEricDing That's a common misunderstanding of optimal virulence. There are many situations where viruses evolve to become more virulent. For example, a disease that spreads when the host is asymptomatic can often tr

@Di8082 @rosse121 @Stentor69 @MLevitt_NP2013 @TheLancet Optimal virulence is more complicated than that. For example, mosquito-borne diseases can select for being highly virulent. Victims too weak to avoid being bitten transmit more. Another: asymptomat
@Stentor69 @KierenLythgow @MLevitt_NP2013 @TheLancet Optimal virulence is more complicated than that. A disease that spreads when the host is asymptomatic can face selection for higher virulence, not lower. https://t.co/mthe92fxle As you know, COVID-19
