Explanation:
Mathematiclly;
Prevalence of a diseases = product of disease incidence and the average survival time.
Prevelence = (incidence) X (average survival time.)
( 75/100,000 )= (25/100,000) X ????.
but 75/100,000 <u>=0.00075</u>. (Prevalence)
and<u> </u>25/100,000<u>= 0,0025.</u> ( Incidence)
Therefore ;
AVERAGE SURVIVAL TIME = (<u>PREVALENCE / I</u>NCIDENCE
= 0,00075/0,00025.
AVERAGE SURVIVAL TIME = 3 years.
Thus it took them a period of 3 years to survive from diagnosis till death.
