Pandemic Influenza

What creates a pandemic?
Novel virus: No population immunity Cause serious disease_ Transmitted person to person

Influenza Pandemics in the 20th Century
• 1918: Spanish Flu • 1957: Asian Flu• 1969: Hong Kong Flu • Seasonal influenza
strains are pandemic strains of years past
![Page 5: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/5.jpg)
Avian Influenza and Human Influenza• All human influenza viruses arise from
avian viruses • Sometimes humans become victims of an
avian virus strain through close contact with birds
• Avian influenza viruses may evolve into new strains capable of infecting humans
![Page 6: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/6.jpg)
Avian Influenza• Disease of domestic
poultry with a origin in migratory birds
• H5N1classification• Can infect mammals
including humans• Mortality rate of >60%
in humans• Don’t count on
seasonal respite

Control Strategies: Birds
Surveillance
Vaccination
Quarantine
Stamping out

Problems….
• Asia is too big• Lots of pressure for mutation: over thirteen
billion chickens in China alone• Most chickens live in backyard flocks• Lack of compensation for sick/dead
animals• People must choose hunger vs. disease
control• Recent successes or too soon to tell?

H5N1 in Humans: The Beginning
* origin of H5N1 Hong Kong 1997

Avian flu and people
![Page 11: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/11.jpg)
Planning Assumptions• Risk of an influenza pandemic in the future:
100%• H5N1?: Unknown• Susceptibility will be universal• Planning will be based on severity of illness• Viral Illness:
– Incubation 1-4 days– Persons may be infectious before signs of illness
• Pandemic will occur in waves– 6-8 weeks– Multiple waves may occur over 18months-2 years
![Page 12: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/12.jpg)
Don’t worry……we’ve got a plan!
The YOYO strategy

Infection Control: Basic Tools
Vaccine
Antivirals

Social Distancing Maneuvers
• Close schools• Keep children at home• Social distancing in workplace• Liberal leave policies• Home isolation and quarantine• Personal Preparedness
![Page 15: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/15.jpg)
Concerns
• Communities must be ready to implement measures rapidly sustain reasonable compliance
• There is lack of traction for personal and community based preparedness efforts
![Page 16: Pandemic Influenza: What do we know, what should we do?](https://reader036.vdocuments.net/reader036/viewer/2022062520/56815e34550346895dcc95f7/html5/thumbnails/16.jpg)
Is there anything good about the bird flu scare??
• Modernize vaccine production techniques• Improve surveillance for animals and humans• Emphasizes the importance of public health• Modernizes outbreak or disaster communication
systems• Encourages citizens to be prepared for all
hazards
