Pandemic Influenza
A pandemic is a global disease outbreak that occurs when a new influenza
virus emerges for which people have little or no immunity, and for which there
is no vaccine. The disease spreads easily person-to-person, causes serious
illness and can sweep across a country and around the world in a very short
time. It is difficult to predict when the next pandemic will occur or how severe
it will be. Wherever and whenever a pandemic starts, everyone around the world
is at risk. Countries might, through measures such as border closures and travel
restrictions, delay arrival of the virus, but cannot stop it.
| Characteristics and Challenges of a
Pandemic |
- When a pandemic influenza virus
emerges, its rapid global spread is considered inevitable.
- Preparedness activities should
assume that the entire world population would be susceptible.
- Countries might, through measures
such as border closures and travel restrictions, delay arrival of
the virus, but they cannot stop it.
- Most people have little or no
immunity to a pandemic virus. Infection and illness rates soar.
- A substantial percentage of the
world’s population will require some form of medical care.
- Nations unlikely to have the
staff, facilities, equipment and hospital beds need to cope with
large numbers of people who suddenly fall ill.
- Death rates are high, largely
determined by four factors:
|
|
|
- The number of people who become
infected
- The virulence of the virus
- The underlying characteristics and
vulnerability of affected populations
- The effectiveness of preventive
measures
|
- Past pandemics have spread
globally in two and sometimes three waves.
- The need for vaccine is likely to
outstrip supply.
- The supply of antiviral drugs is
also likely to be inadequate early in a pandemic.
- A pandemic can create a shortage
of hospital beds, ventilators and other supplies.
- Surge capacity at non-traditional
sites such as schools may be created to cope with demand.
- Difficult decisions will need to
be made regarding who gets antiviral drugs and vaccines.
- Travel bans, closings of schools
and businesses and cancellations of events could have major impact
on communities and citizens.
- Care for sick family members and
fear of exposure can result in significant worker absenteeism.
