WASHINGTON - The US swine flu death toll reached 22 as one death was reported late Thursday in the eastern state of Pennsylvania.

The Pennsylvania death, as well as deaths in New York and Chicago reported late Wednesday, were not included in the latest figures from the Centers for Disease Control and Prevention.

Pennsylvania currently "has 269 confirmed cases and 101 probable cases of illness due to this virus," the state's Health Department said in a statement.

It was the first death in the state, officials said.

As of midday Wednesday, the CDC reported 17 deaths in the United States attributed to the A(H1N1) virus and 11,054 confirmed cases.

The CDC, which says there are confirmed cases in all 50 US states, currently updates its figures on Monday, Wednesday and Friday.

Swine flu has now spread to at least 66 countries, with more than 19,000 people known to have been infected since the disease was first uncovered in April, according to the most recent data from the World Health Organization out Wednesday.
