Impact of Pandemic Influenza
If a new and severe strain of flu were to begin spreading across the globe, Virginia would not be spared from its impact. The severity of the next pandemic cannot be predicted, but modeling studies suggest that its effect in the United States could be severe. In the absence of any control measures (vaccination or drugs), it has been estimated that in the United States a "medium-level" pandemic could cause:
- 89,000 to 207,000 deaths
- 314,000 to 734,000 hospitalizations
- 18 to 42 million outpatient visits
- 20 to 47 million people becoming sick
- An economic impact ranging between $71.3 and $166.5 billion
In Virginia, pandemic flu impact estimates include:
- 2,700 to 6,300 deaths
- 12,000 to 28,500 hospitalizations
- 575,000 to 1.35 million outpatient visits
- 1.08 million to 2.52 million people becoming sick
Flu pandemics are different from many of the threats for which public health and the health-care system are currently planning:
- The pandemic will last much longer than most other emergency events and may include waves of flu activity separated by months (in 20th century pandemics, a second wave of flu activity occurred three to 12 months after the first wave).
- The numbers of health-care workers and first responders available to work can be expected to be reduced as they will be at high risk of illness through exposure in the community and in health care settings, and some may have to miss work to care for ill family members.
- Resources in many locations could be limited because of how widespread a flu pandemic would be.
