Some of this comes from past epidemics. Which usually happens in a flu type epidemic is people with the mild strain go about their business.

People with the severe strain, stay home. They get better or die off. Thus they don't spread the deadlier form.

Thus overtime the mild strain becomes mainstream.

This was the opposite in the Spanish flu, where the mild strain infected stayed in the trenches and the front lines, while the severely infected were transported in crowded trains to hospitals thus spreading the more deadly version.
