In the first six months of the H1N1 flu pandemic, 22 million Americans fell ill from the virus, the CDC now estimates.
Of those, about 98,000 needed inpatient care, and 3,900 died, according to Anne Schuchat, MD, director of the CDC's National Center for Immunization and Respiratory Diseases.
The estimates are higher than initial counts, which included only laboratory-confirmed cases, Schuchat told reporters in a news conference.
"For influenza it's virtually impossible to find every case with a lab test," she said. "These estimates give a bigger picture of what's going on.".....
The agency also broke its estimates down by age group and found that most cases occurred in those under 65:
•For children under 18, there were an estimated eight million illnesses, 36,000 hospital stays, and 540 deaths.
•For adults from 18 through 64, there were 12 million cases, 53,000 hospital stays, and 2,900 deaths.
•For those 65 and older, there were 2 million cases, 9,000 hospital stays, and 440 deaths.
