PROBLEM IV. WHY IS QUARANTINE NECESSARY? 



Reasons for quarantine. We all know that when a person has 

 a communicable disease, the doctor, acting under orders of the 

 local board of health, puts the patient and sometimes the entire 

 family under quarantine. Since this often seems needless, espe- 

 cially if one has a mild attack of the disease, we ought to know the 

 reason underlying such action. Communicable diseases become 

 epidemic if they are not controlled. Measles, for example, is a dis- 

 ease easily passed from one person to another. It is especially 

 communicable among children, one of whom may have a very light 

 case but may pass the germs to some one else who will have a 

 severe attack of it. Scarlet fever, colds, and influenza are other 

 diseases which are readily spread and may become epidemic. 

 Since this is true, the reason for the isolation of the patient 

 becomes evident. And every one should be unselfish enough to 

 see this and to cooperate with the health authorities for the com- 

 mon good of the community.
