NEW YORK (AP) — At least seven people were in U.S. hospitals with swine flu Tuesday as the number of cases nationwide rose to 64 and a federal health official warned that deaths were likely.
Most of the nation's confirmed cases were in New York, where the city health commissioner said "many hundreds" of schoolchildren were ill at a school where several students had confirmed cases of swine flu.
Richard Besser, acting director of the federal Centers for Disease Control and Prevention, noted that although ordinary human flu accounts for 36,000 deaths every year, he was concerned by this strain.
"I fully expect we will see deaths from this infection," Besser said at an Atlanta news conference.
He said he did not know about a newspaper report of two deaths in two southern California hospitals in which the victims appeared to have suffered from swine flu symptoms.
New York has the largest number of swine flu cases, with a heavy concentration at a Catholic school in Queens where students recently went on a spring break trip to Mexico.
There were indications that the outbreak may have spread beyond the school, with two people having to be hospitalized and officials closing a school for autistic children down the road. Those cases have not been confirmed.
"It is here and it is spreading," New York City Health Commissioner Thomas Frieden said. "We do not know whether it will continue to spread."
Mayor Michael Bloomberg said that 82 of 380 students at P.S. 177, a school for autistic children, have called in sick. A third school in Manhattan is being evaluated because students there are sick, Frieden said.
The CDC said the country has 64 confirmed cases across five states, with 45 in New York, one in Ohio, two in Kansas, six in Texas and 10 in California. At least four other cases have been reported by states.
