If the prevalence is very low as compared to the incidence for a disease, it implies:
Prevalence = Incidence X Mean duration of the disease (P = I X d) Incidence reflects causal factors Duration reflects the prognostic factors In the given question, prevalence is very low as compared to the incidence for a disease. Thus, d has to be low; duration of the disease can be sho under 2 circumstances: Either disease is very fatal, or Disease is easily curable
Disease is very fatal and/or easily curable
Disease is non-fatal
Calculation of prevalence & incidence is wrong
Nothing can be said, as they are independent
