   CARRIER. A person who, without symptoms of a communicable disease, harbors and spreads the infectious agent of that disease.

   COMMUNICABLE DISEASES. Diseases which are communicable through the conveyance of the infectious agent of the disease, directly or indirectly.
   CONCURRENT DISINFECTION. The immediate disinfection or destruction of all infected or presumably infected articles.
   CONTACT. A person has been sufficiently near an infected person or animal to make possible the transmission of the infectious agent to him or her, directly or by articles freshly soiled with the infectious agent.

   INFECTIOUS AGENT. A living microorganism or filterable virus capable under favorable conditions of inciting a communicable disease.
   ISOLATION. The separation of persons suffering from a communicable disease, or carriers of the infectious organism, from persons in those places and under those conditions as will prevent the direct or indirect conveyance of the infectious agent to susceptible persons.
   PERIOD OF COMMUNICABILITY. The time during which a person affected with a communicable disease is capable of transmitting the infectious agent to others.
   QUARANTINE. The confining of persons, animals, or materials within a designated area and excluding other persons, animals or materials from that area for a prescribed period of time as determined by the health officer.
   RENOVATION. In addition to cleansing, the treatment of the walls, floors and ceilings of rooms or houses which may be necessary to place the premises in a satisfactory sanitary condition.
   TERMINAL DISINFECTION. The measures taken to destroy or remove infectious material after the removal of the patient or termination of the isolation at the time when the patient is no longer a source of infection.
