North Dakota's swine flu count has changed little in the past week, with only four new cases reported.

State health officials say the count stands at 57 cases in 14 counties, including 21 males and 36 females. The state Health Department says two of the victims have been hospitalized.

Health officials say 25 of the cases are between the ages of 10 and 19.

Seventeen of the confirmed cases are in Cass County, 12 in Ward County, eight in Burleigh County and seven in Grand Forks County.

Nationwide, federal health officials say the number of U.S. swine flu cases has reached nearly 34,000, with 170 deaths.
