PROBLEM 248 275 



Having determined this point, next apply what you have 

 learned about disinfectants to the particular disease you are trying 

 to prevent the spread of from one person to another. Remember 

 contact with the germ is necessary in order for the well person to 

 take the disease. 



In the case of tuberculosis what methods would you advocate 

 for receiving and destroying the material from the mouth (sputum) 

 containing the disease germs? 



Conclusion. — How would you destroy the disease germs in a 

 given disease such as tuberculosis, typhoid, or diphtheria? 



b. How to prevent the Germs of those Sick from Reaching those in 

 Neighboring Families who are Well. Quarantine 



Method and Observations. — Notice the manner in which your 

 local board of health treats families in which infectious disease 

 has come. 



HOTE. — This isolation of the patient is called Quarantine. Quarantine may be 

 done in the home or by removing the sick person to a hospital where only that 

 particular disease is treated. 



Why should persons ill with a germ disease be isolated until 

 they are well ? What methods have the board of health for warn- 

 ing strangers of the presence of the disease in a home? Why is 

 this necessary? What should be done with heavy rugs, curtains, 

 etc. in the room where one is ill with a germ disease? Why? 

 How could the germs that might lodge in such hangings be killed ? 

 Suggest methods. What do we mean by disinfection ? Look up 

 your local board of health rules on disinfection and note what is 

 used and how used. (See page 390, Civic Biology.) What should 

 be done to the body, clothing, and hair of a person who has been 

 ill with a germ disease before he is allowed to go among well 

 persons again ? Why is this necessary? Would a person be 

 selfish who neglected such precautions? Give reasons. 



Conclusion. — 1. What is the reason for quarantine and by 

 what should it be followed to be effective? • 



2. Why is there a quarantine station at the entrance of New 

 York harbor? Why is it of particular value there?
