Question

1) You study a deadly disease in your community; Methicillin-resistant Staphylococcus aureus (MRSA). It is usually contracted in in-patient facilities. The following information will help you calculate your death statistics. Total population in your community = 97,432. Total deaths this year in the community = 515. Total deaths from MRSA = 21. Total people diagnosed with MRSA = 107. What is the case fatality rate?

A) 1.10/1000

B) 19.63%

C) 4.08%

D) 2.16/10000

E) 5.29/1000

2) You are studying mortality rates due to malaria in a community where spread of the infection by mosquitoes is high. You use the following information to calculate your death statistics. Total population in your community = 590,118. Total deaths this year in the community = 3,895. Total deaths from malaria = 137. Total people diagnosed with malaria = 4,426.

What is the Proportionate Mortality Rate?

A)2.32/10000

B) 3.52%

C) 7.50/1000

D) 6.60/1000

E)3.10%

Answer:

1) You study a deadly disease in your community; Methicillin-resistant Staphylococcus aureus (MRSA). It is usually contracted in in-patient facilities. The following information will help you calculate your death statistics. Total population in your community = 97,432. Total deaths this year in the community = 515. Total deaths from MRSA = 21. Total people diagnosed with MRSA = 107. What is the case fatality rate?

• A) 1.10/1000
• B) 19.63% - Correct Option
• C) 4.08%
• D) 2.16/10000
• E) 5.29/1000

Explanation:

• Total deaths from MRSA = 21
• Total people diagnosed with MRSA = 107.

Case fatality rate = 100* (no. of deaths from a specified disease over time / the number of individuals diagnosed with the disease over time

= 100*(21/107) = 19.63%

2)

You are studying mortality rates due to malaria in a community where spread of the infection by mosquitoes is high. You use the following information to calculate your death statistics. Total population in your community = 590,118. Total deaths this year in the community = 3,895. Total deaths from malaria = 137. Total people diagnosed with malaria = 4,426.

What is the Proportionate Mortality Rate?

• A) 2.32/10000
• B) 3.52% - Correct Option
• C) 7.50/1000
• D) 6.60/1000
• E) 3.10%

Explanation:

Total deaths this year in the community = 3,895.

Total deaths from malaria = 137

Propotionality Mortality rate = (No. of deaths from a specific cause *100) / (total no. of death in the population)

= (137*100)/(3895) = 3.52%
