Is Bird Flu H5N1 the Current Pandemic?NO
  • Bird flu is primarily an animal disease
  • Bird flu primarily spreads from birds to birds
    and from birds to humans
  • but the virus may change so that it is easily
    transmissible from person-to-person, thus causing
    a pandemic

5
What is the flu?
Influenza or Flu is a virus
-- affects the respiratory tract (nose, throat
and lungs)
-- proper treatment is antivirals, not
antibiotics
Flu is very contagious.
-- is easily spread when people sneeze or cough

Seasonal Influenza
  • Can spread rapidly from person to person
  • Is seasonal in the US beginning in the Fall and
    ending in Spring
  • US Impact
  • Average of gt 200,000 influenza-related
    hospitalizations / year
  • Average of gt 36,000 influenza-related deaths /
    year

8
What is pandemic flu (Influenza)?
  • Isolation from humans of a novel influenza A
    virus ? Little or no immunity in the population
  • Demonstrated ability of the virus to replicate
    and cause disease ? Efficient person-to-person
    transmission
  • A flu pandemic is a worldwide epidemic spread of
    a new flu virus

20TH Century Pandemics
1968 Hong Kong Flu
1957 Asian Flu
1918 Spanish Flu
A(H2N2)
A(H3N2)
A(H1N1)
1-4 m deaths 34,000 US deaths
1-4 m deaths 70,000 US deaths
20-40 m deaths 675,000 US deaths
10
Differences between seasonal flu and pandemic flu
  • Seasonal Flu
  • occurs every year, usually in winter, in
    temperate climates
  • Usually some immunity built up from previous
    exposure
  • Healthy adults usually not at risk for serious
    complications
  • Vaccine for seasonal flu is based on known virus
    strains
  • Pandemic Flu
  • Occur sporadically throughout history 2-3 waves
    of 3-4 months- total duration up to 18 months
  • Little or no pre-existing immunity
  • Healthy people of all age groups may be at risk
  • Vaccine probably will not be available in the
    early stages of a pandemic

11
Projected National Impact
  • 40 - 90 million people clinically ill
  • 20 - 46 million (low range ) outpatient medical
    visits
  • 360,000 9,600,000 people hospitalized
  • 104,000 2,200,000 deaths
  • US losses estimated at 71-166 billion
  • Many geographic areas affected at the same time

12
Why The Concern About Pandemic Influenza?
  • Influenza pandemics are inevitable
  • Can cause
  • High levels of sickness and death
  • Drastic disruption of critical services
  • Severe economic losses
  • Outbreaks occur simultaneously in many areas
  • There will be little warning time between the
    onset of spread of a pandemic and its arrival in
    the U.S.
  • Impacts will last for weeks to months
  • Pandemics can disproportionately affect younger,
    working-age people
  • Current avian influenza outbreak in Asia
  • Vaccine not available until 6-9 months after
    start
  • Anti-virals limited supply, questionable efficacy

13
NEW CDC Pre-Pandemic Planning Guidance
  • Focuses on non-pharmaceutical measures
  • Asks communities, including schools to plan using
    these interventions
  • Introduces a Pandemic Severity Index
  • Contains tailored planning guides for communities
    and includes guidance for child care programs,
    elementary and secondary schools, colleges and
    universities
  • www.pandemicflu.gov

14
Interim Pre-pandemic Planning Guidance
  • Objectives are to
  • buy time for production and distribution of a
    well matched vaccine
  • reduce the burdens on the healthcare
    infrastructure
  • reduce morbidity and mortality

15
Pandemic Severity Index (PSI)
  • The guidance introduces the Pandemic Severity
    Index (PSI)
  • 5-point scale based on the case fatality ratio
    (CFR) to categorize pandemic severity
  • Category 1 Seasonal
  • Category 2-3 1957, 1968
  • Category 4-5 1918

16
Pandemic Severity Index
17
Summary of Pandemic Severity Index
18
Sample Community Mitigation Recommendations from
the CDC
  • Sick people should remain at home for 7-10 days
  • Household members of a person who is ill should
    remain at home for 7 days
  • Dismiss students from all schools and
    school-based activities and close of childcare
    programs for up to 12 weeks at a time.
  • Increase social distancing by cancellation of
    large public gatherings and changing workplace
    environments and schedules.

19
Key Messages to Schools
  • Collaborate with the local health department
  • Teach and reinforce preventive hygiene
  • Encourage staff, students, and parents to get
    seasonal flu shots
  • Encourage staff and students who are sick to stay
    home
  • Review the CDE checklists
  • For K-12 schools
  • For preschools
  • Review, update, practice school emergency plans

Pandemic Influenza Preparedness For Schools
  • In August, 2007, Department of Public Health
    mailed a DVD/CD of the May 17 Webcast to each
    district and county office.
