COMMON COMMUNICABLE DISEASES. 



used in these places and which form favorite 

 haunts for the mosquitoes, are screened also. 

 All pools and swamps are treated with oil and 

 in some places drained and filled in. 



Bubonic Plague is caused by the bacillus 

 pestis. The seat of invasion of this germ is The Bacillus 

 the skin and subcutaneous tissues, the lym- 

 phatics, the lungs and the intestinal tract. 

 Authorities teach us that the pneumonic form 

 is the most dangerous and the most readily 

 communicable. All the discharges, clothing, 

 etc., must be treated to a hot carbolic acid solu- 

 tion bath, strength 1-20. Floors and wood- 

 work must be washed daily with a solution of 

 bichloride of mercury 1-1,000. Patients must 

 be rigidly isolated and dead bodies cremated. 

 While this disease is one commonly confined to 

 Eastern countries, it may be carried into our 

 ports on ships infested with rats, mice and 

 other vermin. This germ has the power 

 to enter the body through wounds, the alimen- 

 tary canal, or the respiratory tract. The in- 

 fection is thrown off in the pus from wounds, 

 in sputum and in discharges from the body. 

 When a wound is invaded by the germs, a 

 severe local inflammation results and quickly 

 spreads to the lymphatic glands. Flies and 

 other insects transmit the disease. Adhere 

 rigidly to personal disinfection at the close of 

 the case, and all through the case.
