DES MOINES, Iowa (AP) - About 150 cases are being tested for swine flu in Iowa but so far no cases of the illness have been confirmed in the state.

State health officials say those tests have been forwarded to the University Hygienic Laboratory in Iowa City.

Health department spokeswoman Polly Carver-Kimm says that if tests at the lab meet certain criteria, a case would be classified as probable and forwarded to the Centers for Disease Control and Prevention for confirmation.

One case is in the Waterloo area, where local health officials say a person showed up a a hospital or clinic Tuesday evening with symptoms that met the definition of swine flu.

Nearly 100 cases of swine flu have been confirmed in 10 states. A young child in Texas died from the illness, which has killed 159 in Mexico.
