EXERCISE 61 A 

 WHAT IS THE SIGNIFICANCE OF THE LOCAL DEATH HATE FROM TYPHOID? 



Materials. Local records regarding number of cases of sickness and death from typhoid. These 

 records should be available in the office of the local health officers, and those covering a period of 

 years will be needed. 



Directions. Secure the local death rate from typhoid if possible. Consult the board of health or 

 health officer. If there are no such officials, consult the physicians or the state board of health. The 

 same authority should be able to give you the typhoid rate in a number of other places. How does 

 your community compare with others ? If its rate is not so low as some others, try to learn why. 



Additional problem. What is the relation of flies to distribution of typhoid ? Would there be danger of 

 securing typhoid germs from flies if all typhoid material from persons ill with typhoid were sterilized ? 

 What are the reasons for the campaign to prevent the reproduction of flies ?
