April 28, 2009 -- At least 66 people in the U.S. have been sickened by swine influenza (swine flu), including five people who have been hospitalized, according to health officials.

The CDC today reported 64 lab-confirmed cases of swine flu:

  • New York City: 45 cases
  • California: 10 cases (including three hospitalized patients)
  • Texas: 6 cases (including two hospitalized patients)
  • Kansas: 2 cases
  • Ohio: 1 case

The CDC's count doesn't include an eleventh California case confirmed by California's health department and another case in Indiana, confirmed by Indiana's health department.

The CDC updates its case count once a day, so there may be some lag time between a state's report and the CDC's daily tally, notes Richard Besser, MD, the CDC's acting director.

Despite recent hospitalizations, cases in the U.S. are still "milder" than those reported in Mexico, according to Besser.

But that could change. "I fully expect that we will see deaths from this infection," Besser said. He pointed out that ordinary seasonal flu can be deadly, killing about 36,000 people in a typical flu season.

Besser said that the median age of swine flu patients is 16, with patient ages ranging from 7 to 54. The earliest lab-confirmed case in the U.S. began on March 28 and the most recent one began on April 24. The virus appears to incubate for two to seven days, which is a typical time frame for a flu virus, Besser notes.
