CDC via Atlanta JournalSATURDAY, May 16 (HealthDay News) -- While the official tally of confirmed U.S. swine flu cases topped 4,700 on Friday, experts at the Centers for Disease Control and Prevention now estimate the true number of infections at more than 100,000 nationwide.

The new swine flu virus is spreading rapidly around the United States, and more than half of the states are reporting unusually high levels of flu-like illness at a time of year when the respiratory disease usually disappears, federal health officials said yesterday.
About half of the people with flu are testing positive for the new virus, indicating it is playing a significant role in the unusual pattern of disease, officials said.
"We would be expecting to see the season to be slowing down or almost completely stopped," said Daniel Jernigan of the federal Centers for Disease Control and Prevention. "But what we're seeing is there are some areas that actually have reports of the amounts of respiratory disease . . . that are equivalent to peak influenza season."
The CDC has officially reported 4,714 confirmed or "probable" swine flu cases in 47 states, and 22 states are reporting widespread flu,
but there could be as many as 100,000 cases around the country, Jernigan said.
"This is not something we would expect to see at this time," said Jernigan, adding that the rising count is not simply the result of doctors looking harder for cases.

The World Health Organisation says the number of confirmed swine flu cases has risen by nearly 1,000 in 24 hours to 8,451. The increased toll comes as health experts defend Mexico and the WHO in their handling of swine flu, an outbreak that has sparked a global alert and is likely to cost billions of dollars.
The number of people killed by the influenza A (H1N1) virus also rose to 72, compared with 65 on Friday, the WHO said. Over the past week the number of people infected by the virus has risen sharply with the United States, followed by Mexico, where the epidemic began, recording the highest number of cases.
A mathematical study, published in the US journal Science this week, showed that the virus, while contagious, has a case fatality rate at 0.4-0.6 per cent - far lower than feared although somewhat higher than a normal "seasonal" flu.
"It's clear that we are facing a virus that is not the virus we were actually afraid of facing at the time of the initial testing," Dr Pittet said. But, he said, the peril was far from resolved.

Swine flu not the only bug going around in the U.S.Seasonal cases up at a time when they should be slowing
BY MARILYNN MARCHIONE

U.S. health officials are seeing a surprisingly high number of cases of ordinary, seasonal flu at a time when the flu season typically peters out.
About half of the people recently testing positive for the flu have the new swine flu virus, Dr. Daniel Jernigan of the Centers for Disease Control and Prevention in Atlanta said Friday.
The rest have seasonal flu, which still is causing widespread or regional illness in about two dozen states, "something that we would not expect at this time," he said. "We would be expecting the season to be slowing down or almost completely stopped."
The higher numbers of seasonal flu cases do not seem to be caused just by health officials looking harder this year because of worries about swine flu, Jernigan said. A network of doctors that tracks how many patients are coming in with flu-like symptoms, plus evidence from school outbreaks and lab testing, points to more flu -- not just more reporting, he said.
Swine flu continues to affect more younger people -- those ages 5 to 24 -- and the CDC still is seeing relatively few cases in older people.
