  • Kevin G. Pearce, MPA
  • Peninsula Health District
  • Virginia Department of Health
  • August 2006

2
Why the concern?
  • Pandemic ( worldwide) epidemic of a new
    influenza virus
  • New virus ? Most people will have no immunity
  • Higher disease attack rates higher death rates
    than seasonal or normal influenza

3
Past influenza pandemics
  • Pandemic flu is unpredictable, like the flu virus
    itself
  • 1968-69 Hong Kong flu
  • 34,000 deaths in US
  • 1957-58 Asian flu
  • 70,000 deaths in US
  • 1918-1919 Spanish flu
  • gt500,000 deaths in US
  • Worst case scenario

4
Why the concern?
  • Pandemic ? rapid spread around world in repeating
    waves
  • 1918 waves circled globe in 6-9 months

United Kingdom experience Jordan E, American
Medical Association, 1927
5
High death rate among young adults
  • Influenza pneumonia mortality per 100,000
    person, by age group

6
Why the concern?
  • Extremely disruptive
  • Worker absenteeism
  • Lost productivity
  • Unable to get/transport supplies raw materials
  • Uncertain infrastructure
  • Fuel utilities telecom info technology
  • Public safety personnel public services
  • Food medicine suppliers
  • Increased demands on health care infrastructure
    workforce
  • Reduced tourism, travel, entertaining, hotels
  • No help from other areastheyre affected

7
What if
  • On the Peninsulawe saw a 35 attack rate over 2
    months (approx. 163,000 ill)

Estimates using CDCs FluAid 2.0

H5N1 avian influenza
  • H5N1current epidemic avian flu strain
  • Highly pathogenic avian influenza (HPAI)
  • Continuous circulation in Asia since 2003
  • Historically unprecedented avian pandemic
  • Magnitude duration of pandemic in birds
  • Virus is changing

11
H5N1 avian influenza(Nations with confirmed
cases July 7, 2006)
12
H5N1 avian influenza
  • Before 1997, H5 influenza virus never infected
    humans
  • Now
  • Human cases from close exposure to ill birds
  • No sustained human-to-human transmission
  • Few cases, but high fatality (gt50)
  • 229 cases 131 deaths, World Health
    Organization, July 4, 2006
  • Treatment primarily supportive
  • Antivirals (Tamiflu Relenza)

13
Is H5N1 a pandemic virus?
  • 3 requirements
  • v Novel strain - new H /or N subtype
  • v Causes significant disease in humans
  • NO Consistent human-to-human transmission
  • Avian H5N1 influenza virus is not a pandemic
    virus - but it might become one

PreparednessPlanning
  • National Strategy for Pandemic Influenza,
    November 1, 2005
  • HHS Pandemic Influenza Plan, November 2005
  • www.pandemicflu.gov
  • Virginia Department of Health Emergency
    Operations Plan Pandemic Influenza Attachment,
    Updated March 2006
  • www.vdh.virginia.gov/PandemicFlu/index.asp

16
PreparednessWhere do we stand?
  • No ready-to-use H5N1 vaccine
  • Antivirals
  • Limited supply of Tamiflu
  • Production in next 10 years will treat only 20
    of world population
  • Unclear if Tamiflu will work for treatment
  • Not enough available to use for prevention

17
Preparedness strategies
  • Heightened surveillance
  • Immediate response at 1st sign of an outbreak
  • Respond to limit and confine outbreak
  • Buy time to make vaccine and take other actions
  • Applies to both humans and birds

18
Control strategies
  • Isolation quarantine
  • Non-pharmaceutical approaches
  • Cough hand hygiene
  • Travel restrictions
  • Social distancing
  • Eliminate mass gatherings
  • Close schools, theaters, etc.
  • General public wears masks

    supplies on hand.

  • To wash hands frequently with soap and water
  • To cover coughs and sneezes with tissues
  • To stay away from others as much as possible if
    they are sick
  • To stay home from work and school if sick.
  • Talk with family members and loved ones about how
    they would be cared for if they got sick, or what
    will be needed to care for them in their home.

20
Why?

    and organizations is vital to a communitys
    successful response to pandemic influenza.

21
