If a virus developed a mutation so that it became much less likely to kill people who were infected, what do you think this would do to the prevalence, incidence, and mortality of the viral infection? You can assume that every other characteristic of the virus stays the same, including the length of infection and how infectious the virus is. Please answer in 4 or less sentences and include an explanation for why you believe something will happen to each of the three disease measures.

Answer #1

Answer

If a virus developed the mutation so that it became much less likely to kill people who are infected then prevalence and incidence disease will remain same but mortality will be reduced. This phenomenon happens because a mutation in the virus may only reduce the infection severity but not the incidence and prevalence. So decreased infection severity causes less mortality in the population.
