NEW YORK (AP) âÄî Health officials in New York say that the swine flu virus that sickened students at a high school is the same strain as the one found in Mexico. The health department stresses that all the cases in New York are milder than the ones in Mexico. But they confirmed that the strains are the same. Tests earlier confirmed that eight students at a private Catholic high school had contracted swine flu. Some of the school’s students had visited Mexico on a spring break trip two weeks ago.
