How would a pandemic impact Australia
How would a pandemic impact Australia 3,5
A flu pandemic may strike in waves, each of which could last for 6 to 8 weeks. An especially severe pandemic could lead to widespread illness, a large number of deaths, and economic loss. Everyday life would be disrupted because so many people in so many places would become seriously ill at the same time. 3,5
Impact could range from school and business closings to the interruption of such basic services as public transportation and food delivery.
A substantial portion of the worlds' population would require some form of medical care. Healthcare facilities would be overwhelmed, creating a strain on hospital staff, and a shortage of beds, ventilators, and other supplies.
To cope with the demand, "surge capacity" at non-traditional sites, such as schools, may need to be created. The need for vaccine is likely to outstrip supply and the supply of antiviral drugs is also likely to be inadequate early in a pandemic. Difficult decisions would need to be made regarding who gets these vaccines and antivirals.3,5
High mortality rates3,5,10
Mortality rates are determined by four factors:
- Number of people who become infected
- Virulence of the virus
- Underlying characteristics and vulnerability of affected populations
- Availability and effectiveness of preventive measures
