Occupational Health

Understanding and preventing health problems related to work and work environments.

Hazard

Something with the potential to cause harm to human health.

Exposure

Contact between a person and a hazard.

Exposure Route

How a hazard enters or contacts the body, including inhalation, ingestion, or dermal contact.

Acute Health Effect

A health effect occurring relatively soon after exposure.

Chronic Health Effect

A health effect developing or persisting over a longer period.

Hierarchy of Controls

A framework for selecting ways to prevent or reduce exposure.

Elimination, Substitution, engineering controls, administrative controls, PPE.

Hierarchy of Controls

Administrative Control

Changing how or when people work.

Engineering Control

Isolating people from a hazard.

Public Health

Protecting and improving the health of populations through prevention and organized action.

Disease

A condition that disrupts normal functioning and produces adverse health effects.

Epidemic

Disease occurrence in a population above what is normally expected.

Isolation

Separating people who are ill form people who are not ill.

Quarentine

Restricting the movement of people who may have been exposed to disease.

Imported Case or Outbreak

A case or outbreak introduced into a population from another geographic location.

Transportation Network

A connected system through which people, animals, and goods move between places.

One Health

An approach recognizing that the health of humans, animals, and the environment are interconnected.

Germ Theory

The scientific concept that microorganisms can cause disease.

Pathogen

A biological agent capable of causing disease.

Pathogenicity

The ability of a microorganism to cause disease.

Virulence

The degree of pathogenicity or capacity or a pathogen to cause disease.

Virulence Factor

A structure or characteristic that increases a microorganisms ability to infect a host, overcome host defenses, or cause damage.

Infectious Dose

The amount of an infectious agen needed to establish an infection.

Agent

A microorganism or other infectious material that causes disease.

Reservoir

An organism or environment in which an infectious agent normally lives and is maintained.

Vector

An organism that can carry infectious agents from one host to another.

Susceptible Host

A person or animal that can become infected by an infectious agent.

Transmission Route

The way an infectious agent moves from its source or reservoir to a susceptible host.

Vector-Borne Transmission

Transmission of an infectious agent through a living vector.

Yersinia Pestis

The bacterium that causes plague.

What is The Yersinia Pestis Transmission Route.

The Yersinia Pestis Transmission Route is from rodents to fleas to humans. Fleas can be vectors, transmitting the bacterium from infected animal reservoirs to humans through bites.

Why did the doctor not believe Charles Monet's friend?

She exhibited no symptoms

Contact Tracing

Trying to locate someone who has been exposed to disease.
