Seasonal Influenza
Illness caused by the influenza virusExtremely contagious and spreads quickly to others. Symptoms vary from person to person Occurs every year, usually in the fall and winter killing 36,000 people in U.S.

Flu Prevention
Get the flu vaccine each year due to high mutation rate of the virus.Practice good hygiene and personal health habits.Cover your mouth when sneezing and wash your hands regularly as the virus spreads through aerosols.Stay at home when sick.

Flu Treatment
Bed restHydration-with eight ounces of fluid every hourAcetaminophen, ibuprofen, naproxenAvoid aspirin when dealing with childrenSince the flu is a virus, antibiotics won’t work unless there is a secondary bacterial infection.

What is Pandemic Flu?
Epidemic: serious outbreak in a single community, population or regionPandemic: an epidemic spreading around the world affecting hundreds of thousands of people, across many countriesPandemic flu: a pandemic that results from an influenza virus strain that humans have not been previously exposed to
Slide12
• A disease outbreak that spreads rapidly and affects many people world wide• Characteristics - New virus that spreads easily as most people are susceptible (no natural resistance or immunity) - Effective human to human transmission is necessary - Measured by how fast the virus spreads - Wide geographic spread• Not predictable• Outbreaks lasting 8-12 weeks with 1-3 week wave cycles

Pandemic Influenza
Slide13
• Pandemics occur in multiple waves of disease outbreaks• The first wave in a local area is likely to last six to eight weeks• The time between pandemic waves varies and can not be easily predicted.• Anticipate 1-3 waves

Past Pandemics
Occurs unpredictably, not always in winter
Variations in:
Case fatality rates (number of people diagnosed with a disease that die from that disease)
Severity of illness
Pattern of illness (ages most severely affected)
Rapid surge in number of cases over brief period of time
Tend to occur in waves - May only be one wave

Perspective
2001 terrorist attack with anthrax - killed five people2002 outbreak of West Nile Virus - killed 284 people nationally in six months2003 SARS outbreak - killed over 800 people world wide - froze Asian economies - frightened millions of people into wearing masks on the streets

Becoming a Pandemic
For pandemic influenza to occur, three conditions must be met:
A new virus which humans are not immune
emerges
The virus causes severe human illness or
death in humans
The virus spreads easily from person to person worldwide
H5N1 has two of the three today.

Little/no spread among humans
Small clusters, localized
Limited spread among humans
Increased and sustained spread in general human population
No new virus in humans
Animal viruses low risk to humans
No new virus in humansAnimal viruses low risk to humans
Current H5N1 status
Slide20
• Crisis for extended period of time in multiple locations• Daily routines will be affected from personal, community, and professional changes - Isolation/quarantine guidelines or requirements? - Cancellation of public events and schools? - Non-essential work activities limited? - Commerce Patterns changed?

Expectations of Pandemics
Slide21
• Elements of personal action will be required• Absenteeism from pandemic flu expected to be 40-60%• Lost availability for those who are ill (or caring for ill family) is projected at 2-4 weeks

Pandemic Possibility
World Health Organization assures us that there will be another influenza pandemic.Unknown when it will occur/how severe the next pandemic will beUnknown what the organism will be
Slide23
• A vaccine to protect people from pandemic flu is not available now.• A vaccine may not be available at the start of a flu pandemic (~ 6-8 months after start).• The best protection is to practice healthy hygiene to stay well now and during a flu pandemic.

Medications During Pandemic Flu
Antiviral MedicationsCan prevent complications if taken within first 48 hours of illnessMay not be effective against a pandemic flu virusExtremely limited supply nowWould be prioritized Initial use probably only for treatment, not prophylaxis
Antiviral Medications
Amatadine
(
Symmetrel
)
Rimantadine
(
Flumadine
)
Zanamivir (Relenza)
Oseltamivir
(Tamiflu)
