The following words as used in these regulations shall have the following meanings, unless a different meaning is required by context or is specifically prescribed:
Includes the boards, department or officer having like powers and duties in cities or towns.
A person who, without symptoms of a disease dangerous to the public health, harbors and may disseminate the specific microorganisms of that disease.
Any person known to have been sufficiently near an infected person or animal to have been presumably exposed to transfer of infectious material directly or by articles freshly soiled with such material.
An "immune" person is one who has had the disease or has been artificially immunized against it, and is presumably protected against another attack.
The usual period of time which elapses between the exposure of a person to infection and the development of the symptoms of the disease to which he may have been exposed.
The separation of persons suffering from any disease dangerous to the public health, or carriers of the infecting microorganisms, from other persons, in such places and under such conditions as will prevent the direct or indirect conveyance of the infectious agent to susceptible persons.
The date of the removal to a hospital, or the recovery or death of the patients or the date on which the nonimmune contact leaves and remains out of the house where the patient is isolated.
An official notice, written or printed, posted as a warning of the presence of disease dangerous to the public health on the premises or in the apartment or room so placarded.
The restriction to the premises, house or apartment of materials and persons that presumably have been exposed to a disease dangerous to the public health. [Note: In view of the various ambiguous and inaccurate uses to which the words "isolation" and "quarantine" are frequently put, it has seemed best to adopt arbitrarily the word "isolation" as describing the limitation put upon the movements of an individual (or animal) known to be sick or to be a "carrier," and the word "quarantine" as describing the limitation put upon individuals exposed (contacts) to disease.]
A "susceptible" or "nonimmune" person is one who is not known to have acquired immunity to the particular communicable disease in question.
