More swine flu cases reported in U.S.

NEW YORK — At least two cases of the human swine influenza have been confirmed in Kansas and one more in California, bringing the U.S. total to 11. At least eight students at a New York City high school probably have swine flu, but health officials said Saturday they don't know whether they have the same strain of the virus that has killed scores of people in Mexico.

Kansas health officials said Saturday they had confirmed swine flu in a married couple living in the central part of the state after the husband visited Mexico. The couple, who live in Dickinson County, were not hospitalized, and the state described their illnesses as mild.

Dr. Jason Eberhart-Phillips, the state health officer, said, "Fortunately, the man and woman understand the gravity of the situation and are very willing to isolate themselves."

The man traveled to Mexico last week for a professional conference and became ill after he returned home. His wife became ill later. Their doctor suspected swine flu, but it wasn't confirmed until flu specimens were flown to the federal Centers for Disease Control and Prevention in Atlanta.

At least nine swine flu cases have been reported in California and Texas. The new California case, the seventh there, was a 35-year-old Imperial County woman who was hospitalized but recovered. The woman, whose illness began in early April, had no known contact with the other cases.

The 11 U.S. swine flu victims range in age from 9 to over 50. All recovered or are recovering; at least two were hospitalized.

Health officials are worried because people appear to have no immunity to the virus, a combination of bird, swine and human influenzas. Also, the virus presents itself like other swine flus, but none of the U.S. cases appears to involve direct contact with pigs, said Eberhart-Phillips, who called the strain "a completely novel virus."

"It appears to be able to transmit easily between humans," Eberhart-Phillips said. "It's something that could potentially become very big, and we're only seeing, potentially, the very beginning of a widespread outbreak."

New York health officials said more than 100 students at the private St. Francis Preparatory School in Queens had come down with a fever, sore throat and other aches and pains in the past few days. Some of their relatives also have been ill.

New York City Health Commissioner Thomas Frieden said nose and throat swabs had confirmed that eight students had a non-human strain of influenza type A, indicating probable cases of swine flu, but the exact subtypes were still unknown.
