SEC. 5

(Reference: Section 2502, Title 17, California Administrative Code)

A.

Definition:

An outbreak is defined as an unusually high incidence of a disease in excess of normal expectancy in a given area or population group. One case of smallpox constitutes an outbreak, while several cases of measles, mumps or hepatitis in the population at large could be considered a normal occurrence. However, when these cases occur in a localized area of the community, a classroom, industry, apartment complex, hospital, etc., they would be considered outbreaks.

B.

General Procedures:

Knowledge of an outbreak of infectious or parasitic disease or infestation, whether or not reportable, is investigated by the District Health Officer and reported to the Chief, Acute Communicable Disease Control. When the outbreak occurs anywhere other than in a health care facility, it is reported on the GENERAL INVESTIGATION RECORD, SDH-262501.

C.

Health Care Facility Outbreaks:

Whoever receives knowledge of an outbreak initiates the CD OUTBREAK NOTICE—HEALTH CARE FACILITY, H-1163 and additionally, telephones Acute Communicable Disease Control when outbreak occurs in an acute care hospital.

SEC. 8 - CHANGE OF RESIDENCE OF PERSONS IN STRICT ISOLATION OR QUARANTINE INCLUDING COMMUNICABLE TUBERCULOSIS

When it is necessary for persons in strict isolation or quarantine to move, written permission is first obtained from the owner of the new premises or his agent.

Moving into a multiple dwelling is evaluated individually considering the disease and situation; any change of residence is under the supervision of the District Health Officer of the Chief, Public Health Investigation.

All cases covered by this section must be reported immediately to the District Health Officer, and in cases of legal isolation and quarantine, to the Chief, Public Health Investigation.
