Question

Multiple sclerosis has a prevalence of 55 per 100,000 and an incidence of 5 per 100,000. What is the duration of the disease? (This is a critical thinking question. You may not find duration calculations. Think of what you know about incidence and prevalence.

Answer 1

Input what you know into the equation and solve for "x".
