Physical Agents
What type of Causative Agents is this:
Speeding objects and Noise
Physical
an illness
caused by some specific biological
agent or its toxic products that can
be transmitted from an infected
person, animal, or inanimate
reservoir to a susceptible host
Communicable
(infectious) disease
a
disease that cannot be transmitted
from infected host to susceptible host
Noncommunicable
(noninfectious) disease
The establishment of a communicable disease agent in a host organism is called
Infection
many noncommunicable health conditions are
called
multicausation diseases
the ability of a
biological agent to enter and grow
in the host
Infectivity
the capability
of a communicable disease agent to
cause disease in a susceptible host
Pathogenicity
the minimal requirements
for the occurrence and spread
of communicable diseases in a
population—agent, host, and
environment
Communicable disease
model
the cause of the disease or health
problem
Agent (pathogenic agent)
a person or other living
organism that affords subsistence or
lodgment to a communicable agent
under natural conditions
Host
a model
to conceptualize the transmission
of a communicable disease from its
source to a susceptible host
Chain of infection
a person who is sick with a
disease
Case
a person or animal that
harbors a specific communicable
agent in the absence of discernible
clinical disease and serves as a
potential source of infection to others
Carrier
a communicable
disease transmissible under natural
conditions from vertebrate animals
to humans
Zoonosis
a disease that
infects only humans
Anthroponosis
the
immediate transfer of an infectious
agent by direct contact between
infected and susceptible individuals
Direct transmission
communicable disease transmission
involving an intermediate step
Indirect transmission
an inanimate material or
object that can serve as a source of
infection
Vehicle
a living organism, usually an
arthropod (e.g., mosquito, tick, louse,
or flea), that can transmit a communicable agent to susceptible hosts
