DISEASE OUTBREAKS An event that occurs when a disease
spreads in greater numbers than expected.
The two types of disease outbreaks are epidemic and pandemic.
EPIDEMIC A disease that spreads in a certain region.
Lower number of people affected (than pandemic).
Smaller region affected (than pandemic). Ex: Malaria that spreads in a region in
Africa; Swine flu that spreads from Mexico to North America.
PANDEMIC An epidemic that affects the global
population. Higher number of people affected (than
epidemic). Larger region affected. (Usually global) Ex: Malaria - Africa → rest of the world;
Swine - Mexico → New Zealand, Israel, Scotland, and etc.
INFLUENZA PANDEMICS An influenza pandemic occurs when: A new
subtype of virus arises. New viruses may cause a pandemic due to:
Unprepared immune systems Easy transmission/spreading Affects different parts of the world at
different times. Rate of Infection: 6 to 9 months to spread
globally. (Even faster with air travel.)
EXAMPLES OF DISEASE OUTBREAKS The Spanish Influenza killed 40-50 million
people. (1918) The Asian Influenza killed 2 million people.
(1957) Hong Kong influenza killed 1 million
people. (1968)• Severe acute respiratory syndrome (SARS) killed
800 people globally.
TREATMENT AND PREVENTION Antibiotics – treat diseases caused by
bacteria. Vaccines – create immunity against
viruses. Good Hygiene – prevent spread of
germs and bacteria.
