Case fatality rate , Mortality Rate
Case fatality rate , also called case fatality ratio ,:the proportion of people who die from a specified disease among all individuals diagnosed with the disease over a certain period of time Case fatality rate is calculated by dividing the number of deaths from a specified disease over a defined period of time by the number of individuals diagnosed with the disease during that time; the resulting ratio is then multiplied by 100 to yield a percentage mortality rate, another measure of death for a given population As an example , consider two population. One population consists of 1,000 people; 300 of these people have the specified disease, 100 of whom die from the disease. In this case, the mortality rate for the disease is 100 ÷ 1,000 = 0.1, or 10 percent. The case fatality rate is 100 ÷ 300 = 0.33, or 33 percent. The second population also has 1,000 people; 50 people have the disease and 40 die from it. Her...
