In self-isolation, the infected person should separate himself from
usceptibles by a distance of more than five feet, practice good personal hygiene, and
avoid the spreading of disease agents as much as possible.
(2) Quarantine. Quarantine is the restriction of movement or activities of well
persons who may have been exposed to contact with a communicable disease.
The purpose of Quarantine is to prevent contact between these
probable carriers and other people who have not been exposed.
An example of quarantine is the practice of excluding adult diphtheria
contacts from food-handling work until they are proven not to be carriers.
(3) Medical surveillance. Medical surveillance consists in observing and
supervising people who, through association with a disease source, have had an
opportunity to acquire a disease.
Surveillance of these contacts permits early recognition of disease
without restriction of movement.
In the presence of a threatened epidemic, examination of all troops
may be ordered.
(4) Treatment. Prompt and adequate treatment of disease sources assists in
the destruction of the infectious agent.
