Scenario 1:
   • Adias is a community of 100,000 residents. During 2005, there were 
    1,000 deaths from all causes. 300 cases of tuberculosis were 
    diagnosed in Adias in 2005. During 2005, there were 60 deaths from 
    tuberculosis.
   • Define: crude mortality rate, proportionate mortality, case fatality 
    rate, cause specific mortality rate
   1. Calculate the crude mortality rate in Adias. 
   2. Calculate the proportionate mortality in Adias due to tuberculosis. 
   3. Calculate the case fatality rate for tuberculosis in 2005  
   4. Calculate the cause-specific mortality rate for tuberculosis.
   • Adias is a community of 100,000 residents. During 2005, there were 
    1,000 deaths from all causes. 300 cases of tuberculosis were 
    diagnosed in Adias in 2005. During 2005, there were 60 deaths from 
    tuberculosis.
   1- Calculate the crude mortality rate in Adias.
   Crude mortality rate= total no. of deaths / total population X 1000
   = 1,000/ 100,000 X 1,000 = 10 per 1,000
   • Adias is a community of 100,000 residents. During 2005, there were 
    1,000 deaths from all causes. 300 cases of tuberculosis were 
    diagnosed in Adias in 2005. During 2005, there were 60 deaths from 
    tuberculosis.
   2- Calculate the proportionate mortality in Adias due to tuberculosis.
   Proportionate mortality rate= 
   deaths from particular cause (TB)/ total deaths X 100 
   = 60/ 1,000 X 100 = 6%
   * In 2005, 6% of all deaths in Adias were attributed to TB.
   • Adias is a community of 100,000 residents. During 2005, there were 
    1,000 deaths from all causes. 300 cases of tuberculosis were 
    diagnosed in Adias in 2005. During 2005, there were 60 deaths from 
    tuberculosis.
   3- Calculate the case fatality rate for tuberculosis in 2005 
   Case fatality rate= 
   Deaths dues to certain disease (TB)/ Total no. of cases of (TB) X 100 
   = 60/ 300 X 100 = 20% 
   * In 2005, 20% of TB cases were fatal in Adias.
   • Adias is a community of 100,000 residents. During 2005, there were 
    1,000 deaths from all causes. 300 cases of tuberculosis were 
    diagnosed in Adias in 2005. During 2005, there were 60 deaths from 
    tuberculosis.
   4- Calculate the cause-specific mortality rate for tuberculosis.
   Cause-specific mortality rate= 
   deaths from particular cause (TB)/ total population X 100,000
   = 60 / 100,000 X 100,000 = 60 per 100,000
   * In 2005, deaths due to TB in Adias was 60 per 100,000
