A new report by the Presidents Council of Advisers on Science and Technology anticipates a fall resurgence of Influenza A H1N1 pandemic that could potentially overwhelm medical services in the United States with 30 - 60 million people seeking medical care.

The report concludes that the 2009-H1N1 flu is unlikely to resemble the deadly flu pandemic of 1918-19. But in contrast to the benign version of swine flu that emerged in 1976, the report says the current strain “poses a serious health threat” to the nation. The issue is not that the virus is more deadly than other flu strains, but rather that it is likely to infect more people than usual because it is a new strain against which few people have immunity. This could mean that doctors’ offices and hospitals may get filled to capacity.

Report Bullet points suggest that H1N1 could:

• Produce infection of 30–50% of the U.S. population this fall and winter, with symptoms in approximately 20–40% of the population (60–120 million people), more than half of whom would seek medical attention.

• Lead to as many as 1.8 million U.S. hospital admissions during the epidemic, with up to 300,000 patients requiring care in intensive care units (ICUs). Importantly, these very ill patients could occupy 50–100 percent of all ICU beds in affected regions of the country at the peak of the epidemic and could place enormous stress on ICU units, which normally operate close to capacity.

• Cause between 30,000 and 90,000 deaths in the United States, concentrated among children and young adults. In contrast, the 30,000–40,000 annual deaths typically associated with seasonal flu in the United States occur mainly among people over 65. As a result, 2009-H1N1 would lead to many more years of life lost.

• Pose especially high risks for individuals with certain pre-existing conditions, including pregnant women and patients with neurological disorders or respiratory impairment, diabetes, or severe obesity and possibly for certain populations, such as Native Americans.
