disease in others but does not itself become ill
Centers for Disease Control and Prevention (CDC) - Answer-federal agency that
provides facilities and services for investigation, identification, prevention, and control of

Contamination - Answer-condition of being soiled, stained, touched, or otherwise
exposed to harmful agents by the entry of infectious or toxic material into a previously

their spores, are destroyed

from internal causes, such as a disease caused by the structural or functional failure of
an organ or a system.
Exogenous - Answer-outside the body; originating outside the body or produced from
external causes. Such as a disease caused by a bacterial or viral agent foreign to the
body.
Fomite - Answer-nonliving material, such as bed linens, stethoscope, needles, and
many other objects that may host and transfer pathogenic organisms.
Host - Answer-a person or group who because of risk factors may be susceptible to to
disease or illness; an organism in which another, usually parasitic, organism is
nourished and harbored.
Infection Control - Answer-the policies and procedures of a hospital or other health care
facility to minimize the risk of nosocomial and community acquired infection spreading
to patients or other members of the staff.
Iinfection - Answer-caused by an invasion of microorganisms such as bacteria, viruses,

reduce the risk of transmission of microorganisms from both recognized and
unrecognized sources of infection.

Chain of Infection - Answer-1. Infectious Agent (pathogenic microorganisms)
2.Reservoir (infected individual or animal)

4.Method of Transmission (hands, contaminated food, air droplets, contaminated
needle)
5.Entrance (mouth, break in skin, and mucous membrane)
6.Host (another person)
then returns to infectious agent
