Pandemic Planning
5. The Pandemic Clock is ticking…we just don’t know what time it is. Edgar Marcus
University of Washington School of Medicine
6. Influenza pandemics 20th century
7. Influenza pandemics are recurring events
8.
A Pandemic WILL occur:
9. The influenza pandemic of 1918-19 killed more humans than any other disease in a period of similar duration in the history of the world.
Alfred W. Crosby, historian & author
America’s Forgotten Pandemic: The Influenza of 1918
The “Forgotten Pandemic”
10. 1917-18 “Spanish Flu” Avian strain of influenza virus
Virus was similar to current bird flu virus
Spread around the globe in 4-6 months
Had several "waves" of infection (each lasted 6-12 weeks)
Infected between 25-30% of the world population
Killed 40-100 million world-wide
Majority of deaths were in persons 18 to 40 years old
Similar to usual flu symptoms only worse
13. WHO Situational Assessment as at May 2006 Risk of Pandemic is great
The risk will persist
The evolution of the threat cannot be predicted
The early warning systems are weak
Preventative intervention is possible, current testing in Vietnam and Australia
Reduction of morb/mort impeded by inadequate medical supplies
Preparation is the best protection
14. Avian influenza H5N1 virus is now affecting poultry flocks in an increasing number of countries
Aggressive infection - quickly kills whole flocks
Can infect humans - mainly only people living/working with poultry
Over 200 people infected - more than half have died (mortality rate >50%!!!!)
Cannot yet easily spread from person to person H5N1 - The Basics
15. H5N1 - The Basics An Influenza Virus must have three (3) attributes to become a Pandemic Virus:
A novel (new) virus which humans have no immunity ?
The virus causes significant human illness and death ?
The virus can spread easily from person to person x
Avian Flu H5N1 has 2 out of 3 today…
16. Since the H5 and H9 investigation we have learned that a reassortment event that could create a pandemic strain could directly occur in humans potentially increasing the likelihood of a pandemic
With this in mind…Since the H5 and H9 investigation we have learned that a reassortment event that could create a pandemic strain could directly occur in humans potentially increasing the likelihood of a pandemic
With this in mind…
17. Infectivity period: 1 day before, 14 days after
Can be transmitted in 3 main ways:
1. Contact transmission:
Direct - Kissing
Indirect – Sharing
2. Mainly by “droplet” spread:
Coughing, sneezing and talking
Mucous membranes
Virus active on hard surfaces for 48 hours
3. “Aerosol” spread:
Unusual but possible in very crowded conditions
18. WHO Classification of Pandemic Phases Reflects increasing risk of a pandemic
Phases may be skipped (or rapidly moved through)
Pandemic alert period is final opportunity to prepare
20. Could trigger a pandemic similar to 1918-19
But the world is different:
5 billion inhabitants (only 1.5 billion in 1917)
Rapid spread via jet travel
Few stockpiles due to “just in time” economies
No specific antiviral treatments developed
No vaccine (seasonal vaccine NOT protective) A New Pandemic?
21. Human infections (as at 8 May 2006):
Turkey (12 cases, 4 deaths)
Vietnam (93 cases, 42 deaths)
Indonesia (33 cases, 25 deaths)
Cambodia (6 cases, 6 deaths)
Thailand (22 cases, 14 deaths)
China (18 cases, 12 deaths)
Iraq (2 cases, 2 deaths)
Azerbaijan (8 cases, 5 deaths)
Egypt (13 cases, 5 deaths)
H5N1 Avian Flu – where is it now?
23. Risks to universities General effects of a pandemic in the community
7 - 150 million globally will die (WHO)
10x that will require medical attention.
Healthcare systems may become overwhelmed
Essential services may break down as key personnel are infected
Businesses may close, and
International travel may be limited as governments restrict entry.
25. Risks to universities Specific effects of a pandemic in universities
Up to 40% of students may become infected – young healthy people may be the most vulnerable, and have the highest mortality rate
Up to 30% of staff may become infected, up to 50% may be absent at any one time
International students and those studying abroad may be stranded when boarders close
Universities may be forced to close by governments
Universities may be forced to care for residential students unable to return home
27. Pandemic Influenza is different to SARS
29. Highly mobile populations
30. Transmission of the virus within universities
31. Insurance issues
32. Entry point screening on campus
33. Medical care on campus
37. Sample Policy Areas Pandemic planning
Communications – with staff, students and externally
Business continuity – to close, or attempt to continue teaching
Optimizing staff and student health
Reducing the risk of staff and students becoming infected – including door screening, PPE, social distancing
Managing infected staff and students on campus
Assisting travelling staff and students
Managing the deceased
