  1. Epidemic Vs Pandemic 8.L.1.2

  2. 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.

  3. Epidemic and Pandemic:What do they refer to? • The terms epidemic and pandemic usually refer to: • The rate of infectionand/or • The area that is infected

  4. 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.

  5. 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.

  6. Pandemics affect more of the population than an epidemic. • A pandemic is typically in a widespread area (usually 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.

  7. 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.

  8. Past Influenza Pandemics • Spanish Influenza: 191840-50 million dead • Asian Influenza: 19572 million people dead • Hong Kong Influenza: 19681 million dead
