commanding officer. In the United States and its
territories and possessions, quarantine authority
and responsibility is assigned by federal statute
to the USPHS for human diseases, the USDA for
plant and animal diseases, and the Department
of the Interior for wildlife diseases. Local, state,
city, and county authority is also recognized by
the Navy and must be complied with.
By international agreement, four diseases are
quarantinable: cholera, plague, smallpox, and
While emphasis is placed on measures to
prevent the spread of quarantinable diseases, the
Medical Department is responsible for recom-
mending measures to prevent the spread of
all communicable diseases both within and
among the naval establishments and civilian
By international convention a Certificate of
Deratization, or a Certificate of Deratization
Exemption is required of vessels entering most
foreign ports to avoid detention for fumigation.
This certificate must be issued by the USPHS and
is valid for 6 months. MDRs of ships proceeding
to foreign ports must apply for a certificate before
departure. These certificates are obtained by
requesting that a rodent inspection be made by a
USPHS representative. If rodents are present on
inspection, deratization measures are required.
After deratization, a Certificate of Deratization
will be issued. If no rodents are found, a
Certificate of Deratization Exemption will be
Ships proceeding to foreign ports will meet
the quarantine requirements issued by proper
authority of such port. Upon arrival at a foreign
port, local requirements pertaining to quarantine
regulations should be checked.
For ships arriving at ports under the control
of the United States, routine submission of a
Maritime Public Health Declaration as described
in SECNAVINST 6210.2 series will be limited
. Ships that in the 15 days before arriving
in a U.S. port have had any passengers or
crew members with a temperature of 100°F
or higher, which persisted for 2 or more days,
or which was accompanied by a rash, jaundice,
glandular swelling, or diarrhea severe enough
to interrupt normal work or cause death.
. Vessels that have been in a smallpox-
infected country within 15 days before arriving
in the U.S.
. Vessels that have been in a plague-infected
country within 60 days before arriving in the
Vessels arriving in ports are no longer required
to complete a quarantine declaration unless
boarded under the conditions listed above. The
boarding inspector will furnish the declaration.
International Health and USPHS Quarantine
Regulations no longer require ships to use rat
guards except when the ship is berthed in a port
where plague is endemic or where large rat
populations are present. In some CONUS ports,
rat guards are required for all naval vessels.
Interstate movement within the United States
of etiologic agents and persons with com-
municable diseases are governed by federal
regulations. These regulations are designed to
prevent the spread of disease from one state to
another and are enforced by the USPHS and state
health departments. COs should maintain liaison
with the USPHS and regional offices.
No preventive medicine program is complete
without consideration of the health hazards
presented by improper safety practices and
hazardous working conditions.
METALS AND OTHER MATERIALS
When heated to specific temperatures, many
materials give off very toxic fumes. Lead forms
fumes when it is heated or melted. It is primarily
a hazard only if it is being welded, melted, cut,
or while being sprayed in lead-containing paint.
Metal that has been painted with lead-containing
paint is also hazardous when it is being cut or
welded. Using a proper respirator will generally
prevent inhalation of metal fumes.
Selenium is found in many rectifiers that
under certain conditions may break down and give
off irritating fumes. A proper filter respirator
will protect against inhalation. Cadmium-plated
objects must not be heated under any circum-

to a chronic, progressive, fatal disease. Use
extreme caution when working with metal con-
