October 2012 - strawberries imported from China were thought to be contaminated with norovirus. More than 11,000 students were sickened throughout eastern German, with 32 requiring hospitalization. About 500 schools were involved in the outbreak of this norovirus, which is the leading cause of stomach flu.
Transmission?
Same as an
outbreak except the
percentage of overall
deaths caused by the
disease is higher OR
the number infected
dramatically
increases from one
year to the next in an
epidemic.
TERMS YOU SHOULD KNOW: EPIDEMIC
epidemic of severe acute respiratory
syndrome (SARS) in 2003, sickened
about 8,098 people and led to about
774 deaths in 29 countries.
(Transmission: direct/indirect/possible
airborne)
Washington State Secretary of
Health declared a pertussis (whooping
cough) epidemic on April 3, 2012 after
a 1,300% increase in cases were
reported compared with 2011 .
(Transmission: direct/indirect)
A
pandemic
is a global
disease
outbreak.
TERMS YOU SHOULD KNOW: PANDEMIC
1918 Spanish Flu (Virus)
DNA mutated into something more
virulent.
particularly deadly in 20 to 35 year
olds.
First reported case in Kansas
estimated up to 40% of the world's
population was infected – killing 20 to
50 million people.
(Transmission: direct/indirect)
(Rosenburg 2012)
REVIEW QUESTIONS
What factors may determine if a person
who is exposed to a pathogen will
actually become ill?
Why do outbreaks or epidemics end?
E B O L A O U T B R E A K 2 0 1 4
Describe the microbe that causes Ebola
What is the mortality rate? Show your calculations.
Why is this considered an outbreak? When did the outbreak start?
Why is Ebola primarily found in Africa?
What is the transmission vector?
Identify the source of the pathogen (ground zero) and describe the
mode of transmission.
Describe how health care workers protect themselves from exposure
to Ebola.
Describe what countries are doing to reduce the risk of transmission.
STAY FLU FREE CAMPAIGN
Design a poster that will encourage students (and
teachers) • Cover mouth and nose appropriately when coughing
or sneezing• Wash hands properly – especially after using the
restroom• Include flu stats and transmission information
