When a member of a household contracts plague, 

 it is customary to remove the patient to an isolation 

 hospital at once, and to quarantine the house and its 

 remaining members for ten or twelve days, at the 

 same time cleaning and disinfecting the house and 

 its contents to the minutest crevice. 



Patients recovering from plague are kept in quar- 

 antine for four or six weeks after convalescence 

 begins, as the bacilli are often found as late as three 

 weeks after the beginning of convalescence. 



In carrying out prophylactic measures against 

 all infectious diseases the sources and modes of 

 infection should be kept constantly in mind to serve 

 as a guide.
