of this policy, immunization schedules in Navy
and Marine Corps recruit centers and officer in-
doctrination centers have had to be altered from
previous long-standing recommendations.
RECORD OF IMMUNIZATIONS
The yellow PHS Form 731 is prepared for each
member of the Armed Forces. Enter the data by
hand, rubber stamp, or typewriter. The day,
month, and year of each immunization given will
be expressed in this order. Indicate the day in
Arabic numerals; the month spelled out or ab-
breviated, using the first three letters of the word;
and the year expressed in arabic numerals, either
by four digits or by the last two digits. The
members Social Security number must be listed
for identification purposes. Entries for smallpox
vaccines should indicate whether freeze-dried or
liquid vaccine was used. Make sure the origin and
batch number are recorded for yellow fever and
smallpox vaccines. Entries for smallpox, yellow
fever, and cholera must be authenticated by the
DOD Immunization Stamp and the actual
signature of the medical officer or a specifically
designated representative. All other immuniza-
tions are authenticated by initialing. Entries for
tetanus toxoid alone will be recorded as TT.
Entries based on prior official records will have
the following statement added: Transcribed
from official United States Department of
Defense records. Such entries in the case of
smallpox, yellow fever, and cholera shall be
validated by the signature of a medical officer or
a specifically designated representative.
An Immunization Record, SF 601, will be
started for all personnel entering the Navy. It will
be prepared in accordance with chapter 16 of the
Manual of the Medical Department and will con-
tain the Social Security number of the member
for identification purposes.
Communicable diseases, as the name implies,
are those diseases that can be transmitted from
one host to another. They may be transmitted
directly or indirectly to a well person from an in-
fected person or animal, or through the agency
of an intermediate animal host, vector, or in-
animate object. The illnesses produced result from
infectious agents invading and multiplying in the
host, or from their toxins (poisons).
TRANSMISSION OF INFECTIOUS
Any means that brings an infectious agent to
a susceptible human host and results in an ex-
posure to the agent is a method of transmission.
Essentially, there are two types of transmission,
direct and indirect.
1. DIRECT TRANSMISSIONThe trans-
fer, without delay, of an infectious agent
to a point (portal of entry) on a receptive
host where it can enter the body. Examples
of direct transmission are:
a. Direct contactTouching, kissing, or
b. Direct projectionDroplet spray from
coughing, spitting, talking, etc.
c. Direct exposureThe contact of
susceptible tissue with soil, vegetable
2. INDIRECT TRANSMISSIONExamples
of the three types are listed below.
Vehicle-borneInfectious agents are
transferred and deposited on a host at
a suitable point of entry by fomites
(nonliving, inanimate materials or ob-
jects, e.g., toys, bedding, utensils, food,
and drink). The infectious agents must
be present on the fomite; it may or may
not have reproduced.
Vector-borneInfectious agents are
transferred to a susceptible host by in-
sects. There are two types of vector-
MechanicalThe infectious agent
is acquired when an insects body
parts come into contact with con-
taminated materials, objects, or
infected persons, and then make
contact with a susceptible host.
BiologicalThe infectious agent,
after being acquired by an insect,
must go through biological changes
in the insect before it is capable of
producing an infection or disease
when deposited on or in a suscepti-
AirborneThere are two methods of
indirect airborne transmission, by
droplet nuclei (from cough or sneeze)
and dust. In both cases, the infectious
agent may remain airborne for long
periods of time.
