Which statement(s) is (are) true? (There could be one or more than one correct answer(s)) If
incidence (I) staybathe same and duration of disease (D) increases, then Prevalence stays the
same. The number of new cases of COVID-19 is cumulative incidence. If incidence (I) increases
and duration of disease (D) stays the same, then Prevalence (P) stays the same. The number of
diabetics divided by the number of non-diabetics is a proportion. The relationship between
Prevalence (P), Incidence (I), and Duration of Disease (D) is I=P Age adjusted rates allow fair
comparison across populations. If incidence (I) increases and duration of disease (D) stays the
same, then Prevalence. decreases. The denominator of Case Fatality Ratio (CFR) is number of
deaths due to disease and CFR is usually expressed as %. Active surveillance is easier to
maintain for extended periods than passive surveillance If incidence (1) decreases and duration of
disease (D) stays the same, then Prevalence..
