In an Asian country with a population of 6 million people, 60,000 deaths occurred during the year ending December 31, 2009. These included 30,000 deaths from cholera in 100,000 people who were sick with cholera. 1. What was the cause-specific mortality rate from cholera in 2010?2. What was the case-fatality from cholera in 2010?

The cause specific mortality

rate from cholera in 2010 is "5/1000".

Explanation:

The measure of number of deaths

in a population is known as the

mortality rate. Fetal mortality rate,

Infant mortality rate, Maternal

mortality rate are some of the

examples. The mortality which

results from a specific cause

during a specified period in a

population is known as the specific

cause mortality.

The mortality due to a specific

cause in a specific period of time

in a population is known as the

cause specific mortality rate. For

example, calculation of mortality

rate for a specific disease like

tuberculosis, cancer is included in

cause specific mortality rate.

The given data shows that

Total population = 6 million

Number of deaths occurred during

the end of December = 60,000

Number of deaths from the cholera

= 30,000 in 100,000 people

People sick with cholera = 30,000

From the given data cause specific

mortality rate can be calculated

from the formula:

Cause specific mortality rate

Number of deaths from specified cause

Total population

Where,

Number of deaths from the cause

= 30,000

Size of the population at the

midpoint of time period =

6,000,000

Therefore,

Cause specific mortality rate=30,000/6,000,000= 5/1000

Hence, the cause specific mortality

rate from cholera in 2010 is "5/1000".

this is really easy just look up what these words mean
