Cuba reported its first confirmed case of swine flu late Monday, identifying the person as a Mexican student who returned to the island after a vacation in his home country. The Health Ministry announced Cuba's first case in a statement read during the nightly newscast. The statement said a group of students from Mexico began arriving on April 25 - four days before Cuban authorities halted airline flights from Mexico - to resume their studies at a clinic in Matanzas province east of Havana. Fourteen of them arrived suffering from flu-like symptoms. Some of the students who appeared sick were quarantined though most were deemed healthy and released. Tests by the Institute of Tropical Medicine in Havana confirmed that one young man had the swine flu virus, the statement said. It was unclear how many might still be isolated for more testing.
