OTHER DISEASES CAUSED BY BACTERIA 



Measles. Measles is a very serious, infectious disease, not only 

 because bronchitis, pneumonia, and tuberculosis may follow the 

 attack, but because permanent injury may be done the kidneys, 

 ears, eyes, etc. 



How Contracted. The germs spread in the watery matter which 

 runs from a patient's nose, and in the sputum. Whenever a per- 

 son sneezes or coughs or talks, he throws out tiny drops from the 

 mouth into the air. Anyone entering the room or approaching the 

 patient may catch the disease. Measles has been contracted from 

 milk, by shaking hanc's with one who nas measles, or by coming in. 

 contact with the towels, cups, spoons, or any other dishes used by 

 measles patients. 



The germs do not live long after they leave the body a fact 

 which, of course, assists in reducing the chances of spreading the 

 disease. 



After Effects. Soon after recovering from the attack, children 

 may have: 1. weak eyes; 2. bronchitis; 3. broncho-pneumonia; 4. 

 tuberculosis; 5. laryngitis; 6. stomatitis; 7. noma; 8. indigestion; 

 9. meningitis; 10. diseases of the middle ear. 



Long after an attack of measles a person may have: 1. chronic 

 kidney trouble; 2. arterio-sclerosis; 3. nervous trouble. 



Preventing the Spreading of Measles. People leaving the home 

 should not visit the room where the patient is sick. Sterilize dishes 

 and clothes by boiling or placing them in a 5 per cent solution of 

 carbolic acid.
