Risk Communicator Training
for Foreign Animal & Zoonotic Disease
Defense
Scenario 1
Highly Pathogenic Avian
Influenza (HPAI)
Developed by
Susan Gale, DVM
Center for Animal Health and Food Safety
College of Veterinary Medicine
University of Minnesota
In cooperation with
Risk Communication Project
Purpose of Scenario
• Apply Risk Communication principles introduced
in the training module to a fictional event
involving Highly Pathogenic Avian Influenza
• Apply knowledge of zoonotic and foreign animal
disease outbreaks to craft appropriate
messages
• Create risk and crisis communication response
strategies from the perspective of key players
Scene 1
August 30, 2009
Live Bird Market
Anytown, USA
Chickens Go to Market
• Farm A raises free-range
chickens
• These chickens are sold
through a local Live Bird
Market
Live Bird Markets
• Live Bird Markets sell poultry to the public and
butcher the birds
• Final dressing is done by the customer
• Live Bird Markets are exempt from inspection
by State or Federal authorities because the
customer is having an animal that they own
butchered
Chickens Grouped Together
• Chickens from all vendor
farms are put together in
one pen
• Customers select which
chickens they want to buy
and have butchered
Detection: Initial Signs of Disease
• Live Bird Market– Sudden death of several birds in
holding pen
• Bird market owner tosses dead birds into uncovered
outside carcass bin
Detection: Initial Signs of Disease
HUMAN CASE
• Chicken slaughter worker becomes ill and is
hospitalized
• Influenza testing shows ill worker is infected with HPAI
H5N1 virus
• With supportive medical care, the ill worker recovers
H5N1 Virus
Facts about HPAI in Birds
• Highly Pathogenic Avian Influenza (HPAI)
is out of the family ornothmyxviridae. It is a
Type A influenza virus.
• HPAI is highly contagious among birds,
especially domesticated poultry like
chickens, ducks and turkeys
• Mortality rates from HPAI infection in
poultry can reach 90-100% in 48 hours
Facts about HPAI in People
• HPAI transmission from birds to humans occurs
occasionally, the highest risk is to people who
are in direct contact with infected birds
• Up to 60 % of humans infected with HPAI virus
have died
• Human to Human spread is rare
• Main concern is virus mutation which could
make HPAI more virulent in humans
Outbreak Response
• State Veterinarian investigates Live Bird Market as
source of infection and tests chickens, holding
pens and slaughter facility
• Samples are sent to specialized government
laboratories for testing
• Results won’t be known for 2-3 days
Risk Communication Part 1
• A Live Bird Market employee has been diagnosed
with Influenza H5N1 virus and an investigation is
ongoing
• Consider your role as a Risk Communicator in this
scenario.
• Who is your audience? What sources of information
do they have access to?
• How do you address the time of uncertainty while
awaiting test results?

contained?
Recovery
• Eradication efforts contain the outbreak to a
five county area. Time from detection to control
is three months
• 1.3 million chickens are destroyed as a result
of H5N1 outbreak
• No other human H5N1 cases are found
Risk Communication Part 3
• What is your role as a Risk Communicator
once the outbreak has been contained?
• How would your message change?
• How might you be better prepared for the
next outbreak event?
