THIS AN EPIDIMIOLOGY QUESTION... it's a 5 part question.
a) what is the crude mortality rate in this village in 2013?
b) what is the cause-specific mortality rate from malaria in this village in 2013?
c) What is the cumulative incidence of malaria in the village in 2013?
d) What is the incidence rate of malaria in the village in 2013?
e) what is the case fatality rate among people who developed malaria in this village in 2013?
A village in Africa had a population of 3,000 people at the beginning of 2013. 1000 developed malaria over the course of the year. By the end of the year, 100 people had died in this village. Of the dead, 10 had died of malaria, all of whom had developed malaria during 2013. There were no births and no out migration during 2013. Use for the next 5 questions.Explanation / Answer
1. Crude mortality rate
=( Number of deaths during a specified period/total population) x 1000
= (100/3000) x 1000 = 33.33
Therefore the crude mortality rate is 33.33 per 1000 people.
2. Cause-specific mortality rate from malaria
=( Number of deaths due to malaria in specific period/total population) x 1000
= (10/3000) x 1000 = 3.33
Therefore the cause-specific mortality rate from malaria is 3.33 per 1000 people.
3. Cumulative incidence of malaria
=(Number of incidence of malaria in specific period/total population at risk) x 1000
= (1000/3000) x 1000 = 333.33
Therefore the cumulative incidence of malaria is 333.33 per 1000 people.
4. Incidence rate of disease
(Total number of new cases of disease/ total population at risk) x 1000
= 1000/3000 x 1000= 333.33 per 1000 people
5. Case fatality rate: 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.
(10/1000) x 100 = 1% is the case fatality rate of malaria in 2013 in that village
