140 ESSENTIALS OF VETERINARY LAW 



deciding when quarantine must be established or 

 removed, and the style of quarantine to be adopt- 

 ed, is one which implies discretion and considera- 

 tion. This cannot be delegated. But the board 

 or other health authority can employ the services 

 of an officer or private citizen to carry out the 

 methods and acts which the proper health author- 

 ity directs. It is not to be presumed that the 

 officer or board would personally maintain the 

 quarantined^ 



105. What Diseases Quarantinable. Any infec- 

 tious disease, propagated by means of bacteria or 

 protozoa, is subject to quarantine, whenever the 

 welfare of the community demands such action. 

 Quarantine is never justifiable where its mainte- 

 nance does not restrict the disease. Cholera is 

 an infectious disease due to the action of a specific 

 bacillus, but in the light of the present knowledge 

 a quarantine which simply prohibited the entrance 

 or exit of persons from the premises w^ould not be 

 considered as proper quarantine. Yellow fever is 

 a better illustration. Malaria was not formerly 

 considered subject to quarantine, but with our 

 present knowledge, even in the absence of special 

 laws relative to that disease, a quarantine would 

 be justifiable under certain conditions. It would 

 not be justifiable in a community in which there 

 were no anopheline mosquitoes, for there the 

 quarantine would be useless, and therefore un- 

 reasonable. It therefore follows that quarantine 

 is not an invariable method of restricting disease.
