Epidemic Vs Pandemic

8.L.1.2Slide2

Disease Outbreak

A disease outbreak happens when a disease occurs in greater numbers than expected in a community or region, or during a season.

An outbreak may occur in one community or even extend to several countries. It can last days or years.

Sometimes, a single case of a contagious disease is considered an outbreak. This may be true if it is an unknown disease, is new to a community, or has been absent from a population for a long time.

An outbreak is classified as either an epidemic or pandemic. Slide3

Epidemic and Pandemic:

What do they refer to?

The terms epidemic and pandemic usually refer to:

The rate of infection

and/or

The area that is infectedSlide4

Epidemic

An epidemic is defined as an illness or health-related issue that is showing up in more cases than would normally be expected. It occurs when an infectious disease spreads rapidly to many people.

Ex: In 2003, the severe acute respiratory syndrome (SARS) epidemic took the lives of nearly 800 people worldwide. Slide5

Pandemic

The term pandemic normally is used to indicate a far higher number of people affected than an epidemic.

Pandemic also refers to a much larger region being affected.

In the most extreme cases, the entire global population would be affected by a pandemic. Slide6

Pandemics affect more of the population than an epidemic.

A pandemic is typically in a widespread area (

u

sually worldwide) rather than being confined to a particular location or region.

Pandemics tend to affect the global population.

A pandemic does not necessarily mean millions of deaths- it means a geographically widespread epidemic

. Slide7

Influenza Pandemics have occurred more than once

An influenza pandemic occurs when a new subtype of virus arises.

This means humans have little or no immunity so everyone is at risk.

The virus spreads easily from person to person causing a serious illness worldwide.

Virus have the capability to spread worldwide very quickly due to the speed of air travel. Slide8
