Answer #1

The prevalence of Runsif would remain

c) Unchanged.

In the case of a disease intervention not curing the disease but simply preventing death, there would be no change in the prevalence of the disease, simply the disease management would be better. The disease could be managed long-term but the prevalence and incidence rates would be unaffected.
