5. Venereal Diseases: 



Under Provincial legislation passed in 1918, everyone (except lay 

 householders) who is responsible under other laws to report other 

 infectious diseases is required to report venereal diseases, but the 

 patient's name is not to be given (serial numbers to be used instead) 

 unless the patient abandons treatment, whereupon full identification 

 data must be sent the Medical Officer of Health, who must then fol- 

 low up the case and take proper methods for prevention of spread. 

 The legislation is very detailed and complete. Military and civil 

 cooperation is assured also.

 Anthrax, Asiatic Cholera, Bubonic Plague, Glanders, Leprosy,

DEFINITIONS 



: ' Cases" are persons, sick of the disease in question. Those ex- 

 posed to an infected person, during an infectious stage, whether that 

 infected person be sick (a "case") or well (a "carrier"), are known as 

 "contacts.' 1 The contacts may be immune or not, infected or not. 

 It is the fact of exposure to infection that makes them "contacts." 



The term "isolation" means restriction of freedom of an internally 

 infectious person, i.e., of a person sick with the disease (a "case"), or 

 of a person, whether immune or not, who is well but infectious, and 

 therefore is a "carrier." A non-immune "carrier' 1 may become a 

 u case, " if the disease develops in him later. 



The term " quarantine ' ; is properly applied only to restriction of 

 freedom of non-immune well persons who have been so exposed to in- 

 fected persons as to make it likely that they themselves may develop
