An

**attack rate**is defined as the proportion of those who became ill after a specified exposure. For example, in an outbreak of gastroenteritis with 50 cases among a population at risk of. 2500, the**attack rate**of disease is. 50/2500 = 0.02, or. = 2/100, or.How do you calculate morbidity rate?

Incidence

**Morbidity Rate Calculation**is the number of new cases in the time period divided by the number of people in the specified population x 100. This gives you the**morbidity**incidence**rate**.What is the difference between case fatality rate and mortality rate?

A

**mortality rate**— often confused**with a**CFR — is a measure of the number of deaths (in general, or due to a specific cause)**in a**population scaled to the size of that population per unit of time.**Case fatality ratio**is the comparison**between**two**different case fatality rates**, expressed as**ratio**.What are the 10 leading causes of morbidity?
