ObjectivesObjectives

• Understand what avian flu and pandemic flu are

• Describe three things you can do at home to prepare and/or protect yourself and your family

• Describe three things you can do at work to protect yourself and others

• Identify where to get accurate information about pandemic flu

DefinitionsDefinitions

• Seasonal Influenza

• Avian Influenza

• Pandemic Influenza

Seasonal InfluenzaSeasonal Influenza

• Caused by a virus• Infects humans• Usually occurs during the winter• Easily spreads from person to person• Vaccine is available

•Incubation period is usually 1-3 days

•Symptoms

-Fever (often sudden), chills, headache, muscle aches, dry cough, sore throat, weakness, runny nose, may last three to five days or more

-People can shed the virus without showing symptoms of infection

Seasonal InfluenzaSeasonal Influenza

• The virus can be spread:

-Cough/Sneeze

• Most important (within 3 feet)

-Contact

• Contaminated articles

The Burden of Seasonal InfluenzaThe Burden of Seasonal Influenza

• 250,000 to 500,000 deaths globally/yr

• 36,000 deaths and > 200,000 hospitalizations/yr in U.S.

• $37.5 billion in economic costs/yr in U.S. related to influenza and pneumonia

Influenza and Other SpeciesInfluenza and Other Species

Influenza viruses can infect a number of different species, including humans

Other species include:– Birds (Avian)– Pigs– Horses– Seals– Whales

Avian Influenza (“Bird Flu”)Avian Influenza (“Bird Flu”)

• Readily infectious between birds

• Only rarely infects humans

How do humans get the bird “bird flu”?

Through close direct contact with poultry

Not easily passed from bird to human

How a new human influenza virus is How a new human influenza virus is createdcreated

Situation Report: Situation Report: H5N1 Avian Flu in HumansH5N1 Avian Flu in Humans

Human infections associated with close direct contact with infected poultry

High mortality (above 50%)

Does not transmit from human to human efficiently so far

What is a pandemic?What is a pandemic?

• Outbreak is higher than usual number of cases occurring locally

• Pandemic is a worldwide outbreak

Flu Pandemics in the 20th Century

Requirements for a pandemic

•A new virus must emerge (people have not been exposed to it before)

•Infection usually causes serious disease

•The virus must spread as easily as seasonal influenza—by coughing and sneezing

Interpandemic Pandemic Alert Pandemic

Phase 1No new virus in humans

Animal viruses low risk to humans 

Phase 2No new virus in humans

Animal viruses high risk to humans 

Phase 3New virus in humans

Little/no spread among humans

Phase 4Small clusters, localized

Limited spread among humans  

Phase 5Larger clusters, localized

Limited spread among humans

Phase 6Increased and sustained spread in general human population

Current Level

Current Pandemic Status

Planning AssumptionsPlanning Assumptions

• Time from infection to symptoms:– 1-4 days (average 2 days)

• Infectiousness:– Greatest during the first 2 days of illness

may be infectious 1 day BEFORE symptoms

– Infectious for about 5 or more days, children will shed the most virus

– On average, each person will transmit influenza to two others

Planning AssumptionsPlanning Assumptions

• In an affected community an outbreak may last 6-8 weeks

• Absenteeism may be as high as 40% in a severe pandemic

• High rates of illness may occur among school aged children

Things to think about during a Things to think about during a pandemic:pandemic:

• Need to create as safe a work place as possible• Need healthy workers on the job to keep

community functioning• Need workers to remain home when ill• Healthcare may look different during a pandemic

National ResponseNational Response

• Development of a national response plan and checklists to help local communities plan

• Investment of resources into vaccine development and medication reserves

• Control of disease coming from outside the U.S. through isolation/quarantine
