Communicable Disease
A disease that can be transmitted directly or
indirectly from one person to another.
Incubation Period: Time between the invasion by the
pathogen and the onset of symptoms.
Prodromal Period: Refers to the initial stage of a
disease: interval between earliest symptoms &
appearance of rash or fever.
Frequently children/people are contagious during this
period. Symptoms are not specific.
Individual may attend work/school and spread
disease.
Communicable Disease
Fomite- Any material that absorbs and
transmits infection.
Chain of Infection-Refers to way in which
organism is spread and infects individuals.
Preventing spread of infection depends on
breaking the chain.
Careful hand washing is essential to the
containment of infection.
Factors contributing to virulence
of infectious disease
Factors that make one susceptible to acquiring
a disease
Age
Sex
Genetic Makeup
Nutritional Status
Physical/Emotional Health
Immune System
Underlying Conditions
Immunity
Natural or acquired
resistance to infection
Race:Some have
greater immunity to
certain diseases.
Immunity varies from
person to person.
If a person is
immune to one
disease they are not
necessarily immune
to another.
Immunity
Acquired Immunity
Is not due to inherited factors.
BUT…
Is acquired as a result of having the disease or
artificially acquired by vaccines or immune serums.
Vaccines are not strong enough to cause the disease, but
stimulates the body to develop an immune reaction.

Immunity
If immediate protection is needed,
antibodies are obtained from
other sources (animals and some
humans).
Live or dead organisms may be
used.
This type of immunity is called
Passive Immunity. It
acts immediately, but does not
last long as immunity that the body
actively produces.
Breast feeding provides passive
immunity to an infant from his/her
mother’s antibodies that are passed
to it in mother’s breast milk.
