Spanish Flu PandemicSpanish Flu Pandemic
Began September 1918 & Ended April 1919
About 675,000 people died in the United States
Rapidly spread and killed those infected
Asian Flu PandemicAsian Flu Pandemic
Began in February 1957 and ended in early 1958
Was quickly identified and vaccine was created
About 70,000 people died in the United States
Hong Kong Flu PandemicHong Kong Flu Pandemic
Began in September 1968 and ended in March 1969
Virus was similar to Asian fluApproximately 34,000 people died in the
United States
Avian FluAvian FluCurrently no human cases in the United States Currently excellent screening system for
migratory birdsExcellent commercial poultry protectionNo evidence of humans effected by properly
cooked poultryCurrently no effective vaccine Work is proceeding on vaccine for poultry and
humans
Avian Flu Health EstimatesAvian Flu Health Estimates
Should Avian Flu occur as a serious case in the US it is estimated that 90 million people would be effected with 2 million deaths
Short term impacts are projected to be 30% of workers sick in most industries with 2.5% expected to die. Average survivors miss 3 weeks of work.

Projected Avian Flu Economic Projected Avian Flu Economic ImpactImpact
Severe case applying average worker productivity rates loss to the economy would be $600 billion or 5% of the GNP
Huge adverse impact on size of future labor pool
Conclusion- Money spent preventing a pandemic will be well spent.

Influenza Virus (Flu)Influenza Virus (Flu)
Mammals and birds always have flu viruses circulating in their respective populations
Horses, Hogs, Humans, and Birds are just a few of the species that are susceptible to flu viruses
Flu viruses generally stay within species There are some exceptions like Swine flu, which
resides in hogs but can infect turkeys Flu viruses are always changing, that’s why the
human vaccine changes yearly
Avian Influenza (AI)Avian Influenza (AI)
North America has always had Avian Influenza strains circulating in waterfowl, wild birds, and live bird markets
“Asian Bird Flu”(H5N1) is one of many strains of Avian Influenza
Poultry companies are concerned about all avian influenza strains, not just “Asian Bird Flu”
Some Perspective on Some Perspective on Asian Bird Flu (H5N1)Asian Bird Flu (H5N1)
Less than 160 people have died from “Asian Bird Flu” and 265 are known to have gotten sick out of 3.7 Billion people in Asia. Since 2006 48% of the cases and 58% of the deaths have been in Indonesia.
It is not contagious between people People afflicted with this disease had very close
contact with sick birds (live with them, butchered and ate products from sick birds.)
It has been known to be in Asia since 1997 but recently has moved into Africa and Europe
Asian Bird Flu (H5N1) infects Asian Bird Flu (H5N1) infects birds easily but does not infect birds easily but does not infect
people easilypeople easily
Factors in Asia that have Factors in Asia that have facilitated H5N1 Infectionfacilitated H5N1 Infection
Eastern Asia has the most poultry and people living in very close proximity
Unsanitary conditions Live Bird (Wet) Markets are a primary source for
poultry in cities Sick animals are likely to be eaten by impoverished
people Consumption of uncooked meat or poultry products
(such as raw blood) Cockfighting (highly mobile)
Asian Bird Flu(H5N1)Asian Bird Flu(H5N1)
This is not a subtle disease in birdsIt kills birds very quickly and in large
numbers (90% plus)With few exceptions, cases have been in
live markets, free roaming birds or birds kept in primitive conditions
What do you need to know What do you need to know about “Asian Bird Flu”?about “Asian Bird Flu”?
This disease will not sneak up on the U.S. U.S. commercial poultry are at a lower risk of
getting “Asian Bird Flu” than free roaming birds Wild birds, free range poultry, backyard birds,
Live bird markets, and gamecocks are at the highest risk of all Avian Flu
U.S. Poultry companies understand that this is “not just another AI virus” and are taking precautions
How are Poultry Companies How are Poultry Companies responding to the threat?responding to the threat?
All of the major poultry companies are testing all flocks prior to processing to ensure that poultry products are AI free
In the unlikely event of a H5N1 infection in commercial poultry, the flock would not be processed for food. (euthanized on farm)
Consumer Education Message: U.S. poultry products will be safe even if Asian Bird flu comes to U.S. (websites, brochures, articles)
What is being done in USWhat is being done in US
Voluntary (mandatory) surveillance program.
Must test for exports. Mandatory surveillance of live bird markets in
NY, NJ and east coast Increase awareness among poultry health
officials and state officials USDA increase information to small flocks
producers Import ban on poultry from Asia
What is being done in Kentucky?
•Commercial Surveillance Program
•Poultry Health Advisory Board
•Emergency Disease Plan
•Catastrophic Loss Training
•Creation of an indemnity fund for small flocks ($ 204,000) by commercial industry ($102,000) and Ag Development Fund Match ($102,000)
How Poultry Companies are How Poultry Companies are structured to prevent diseasestructured to prevent disease
Chickens are raised indoors to protect from disease-carrying wild birds
A company representative visits the farm weekly to evaluate flock health
Producers alert the company immediately to changes in flock health status
Biosecurity: Procedures that keep disease away from the flock
Poultry BiosecurityPoultry Biosecurity
Unauthorized visitors are not permitted on farm Clean coveralls, hairnets, and disposable boots are
used when visiting farms Step pans disinfect footwear prior to entering Water systems sanitized (especially lake systems) Producers avoid contact with waterfowl,
gamecocks, poultry swap meets, etc.
Why aren’t we vaccinating our Why aren’t we vaccinating our chickens for Asian Bird Flu?chickens for Asian Bird Flu?
Historically, vaccinating for AI meant that a country was not serious about eradication
US Poultry relies heavily on exports: Breast meat stays in domestic markets, Leg quarters go overseas
U.S. companies believe that trade barriers would be imposed if U.S. vaccinated for AI
Overseas opposition to vaccination may vanish as more countries vaccinate for “Asian Bird Flu”
FFLUSTOPLUSTOPFlock Observation
•Observe Flocks Daily
•Changes in appearance, behavior, drinking and eating behavior
•Disease symptoms eat less, respiratory signs, lack of coordination, increase death loss
•Dispose of dead birds properly
FFLLUSTOPUSTOPLimit TrafficAllow only necessary people and vehicles
to enter the farmPost warning signsLog book for visitorsBe aware of areas with birds (hunting,
farm ponds, pet stores, zoos, parks)Minimum level of security is clean boots
FLFLUUSTOPSTOPUnwanted CrittersPrevent contact with wild birdsClean up grain and feed to control wild
birds and rodentsIsolate or cull sick birdsA chicken is the only animal that should be
in a chicken house (keep dogs and cats out)Isolate new or returning poultry from
resident birds for at least 30 days
FLUFLUSSTOPTOPSanitationKeep pens and buildings neat and cleanPrevent wet and damp bedding and eliminate
standing water in pensClean and disinfect all equipment and crates
before returning to the farmEstablish a wash area away from the poultry
buildingsProvide clean boots and clothes for workers
FLUSFLUSTTOPOPTalk to a vet Early detection and reporting are important
steps in preventing a disease outbreak If you notice unusual symptoms or increase
death contact local vet or the office of the State Veterinarian
To report sick wild birds (more than 5 or waterfowl) contact US Fish and Wildlife or the KY Department of Fish and Wildlife
FLUSTFLUSTOOPPObjects spread disease Diseases spread through direct contact with
infected birds Diseases also can be spread by manure,
equipment, vehicles, egg flats, eggshells, crates, and boots
Avoid visiting other poultry farms Do not share equipment but if you must, wash
and disinfect any shared equipment before it is returned to the farm
Do not reuse egg cartons, egg flats or packing materials
FLUSTOFLUSTOPPPrepare food properlyDo not eat, drink or use tobacco products when
handling poultryWash hands and surfaces with hot soapy water
before and after handling raw poultry or eggsKeep raw poultry and their juices away from
other foodsCook poultry to 165o F
Hunter and TaxidermistsHunter and Taxidermists Limit exposure to feces and bodily fluids from
game animals Do not handle or process birds found sick or dead Wear rubber or latex gloves and washable
clothing while handling game Dispose of internal organs, feathers, bones skin,
and trimmings in a safe manner Do not eat, drink, or use tobacco products while
handling game Wash hands with soapy water or alcohol wipes
immediately after handling game
Hunter and TaxidermistsHunter and Taxidermists
Clean all tools and work surfaces with hot soapy water then disinfect with 10% chlorine bleach or other disinfection
Thoroughly cook meat is safe to eat (165oF) Use caution around water sources and roosting
areas were feces from wild birds may accumulate
When finished hunting, clean clothing, boots, vehicles as soon as possible
Do not bring game birds onto poultry farms

What Happened in 1918?What Happened in 1918?
No one had immunityEach individual needed to develop antibodies
so that the individual can fight off the virus.Healthy young adults went into
immunological overload. Caused unexpected high death rate in young
adults.
Would Having a Weak Immune Would Having a Weak Immune Lower the Death Rate in the Lower the Death Rate in the
1918 Pandemic?1918 Pandemic?
There is no evidence that having a weak immune system before the pandemic would have reduced the possibility of having gone into an immune system overload.
Having a weak immune system will make an individual more susceptible to the typical complications of a pandemic or flu.

How might a Pandemic Affect my How might a Pandemic Affect my Community?Community?
Absenteeism - A pandemic could affect as many as 40 percent of the workforce during periods of peak influenza illness. Employees could be absent because they are sick, must care for sick family members or for children if schools or day care centers are closed, are afraid to come to work, or the employer might not be notified that the employee has died.
Change in patterns of commerce - During a pandemic, consumer demand for items related to infection control is likely to increase dramatically, while consumer interest in other goods may decline. Consumers may also change the ways in which they shop as a result of the pandemic. Consumers may try to shop at off-peak hours to reduce contact with other people, show increased interest in home delivery services, or prefer other options, such as drive-through service, to reduce person-to-person contact.
How might a Pandemic Affect my How might a Pandemic Affect my Community?Community?
Interrupted supply/delivery - Shipments of items from those geographic areas severely affected by the pandemic may be delayed or cancelled.
