Microbiology chapter 15

A cloud of tiny liquid droplets suspended in air:

An individual who harbors an infectious agen without having observable or clinical signs or symptoms:

An individual with reduced resistance being more susceptible to infection:

A mode of disease transmission effected directly, indirectly or by droplets:

Mode of disease transmission requiring person to person body contact:

A particle consisting of dried mucus in which microorganisms are embedded:

Contact transmissio of disease through small liquid droplets:

Referring to a disease that is contantly present in a specific population:

Referring to a disease that has a higher than normal incidence in a population over a relatively short period of time:

The assignment or study of causes and origins of a disease:

An infection caused by opportunistic microorganisms already present in the body:

An infection caused by microorganisms that enter the body from the environment:

A nonliving sustance capable of transmitting disease, such as clothing, dishes or paper money

The proportion of individuals in a population who are immune to a particular disease:

Direct contact transmission of disease in which pathogens are usually passed by handshaking, kissing, contact with sores or sexual contact:

An infection that fails to produce symptoms, wither because too few organisms are present or because the host defenses effectively combat the pathogens:

The number of new cases of a particular disease per 100,00 population seen in a specific period of time:

Transmission of disease through fomites:

Transmission of disease in which pathogens from feces of one organism infect another organism (Ex: Typhoid Mary)

Situation in which a patient with a communicable disease is prevented from cotact with the general population:

The number of person contracting a specific disease in relation to the toal population (cases per 100,000)

The number of deaths from a specific disease in relation to the total population:

An infection acquired in a hospital or other medical facility

A disease that a physcian is required to report to public health officials

An epidemic that has become worldwide:

An unmedicated, usually harmless substance given to a recipient as a substitute for or to test the efficacy of a medication or treatment:

A site at which microorganisms can gain access to the body tissues

A site at which microorganisms can leave the body:

The number of people infected with a particular disease at any one time:

An epidemic that arises from person to person contacts:

The separation of humans or animals from the general population when they have a communicable disease or have been exposed to one:

Site where microorganisms cna persist and maintain their ability to infect:

A disease that is limited to a small numer of isolated cases posing no great threats to a large population:

A set of guidelines established by the CDC to reduce the risk of disease transmission in hospital and medical laboratory settings:

An organism that transmits a disease causing organism from one host to another:

A nonliving carrier of an infectious agent from its reservoir to a susceptible host:

Direct contact transmission of disease in which pathogens are passed from parent to offspring in an egg, sperm, across placenta or while traversing the birth canal:

A disease that can be transmitted from animals to humans:
