What does the relative risk value mean?

If the relative risk calculated was (44%) it means their risk of developing the illness is (44) times more

How is relative risk (RR) calculated?

Incidence rate of disease in those exposed to risk factor ÷ incidence rate of disease in those not exposed to risk factor

What's an isolate case?

Presence of pathogens but no signs and symptoms

How would you interpret the results of a relative risk calculation?

RR = 1 - risk of illness is same in exposed and non exposed population RR > 1 - risk is greater in exposed population RR < 1 - risk is greater in non exposed population

What is relative risk?

Ratio between incidence of a disease in members of population exposed to possible risk factor and incidence in non-exposed individuals

What is epidemiology?

The occurrence, distribution and control of disease in populations

What is a suspect case?
