A 30-year-old man has been confirmed to be the fifth A/H1N1 flu virus case in Greece, Greek media reported on Tuesday.

According to Greek TV Net Channel, the young man, who returned from New York three days ago, is being hospitalized in Athens. Doctors said it is a mild case of the flu.

Health authorities have reassured that there is no reason for concern, but called on citizens returning from trips abroad to be particularly cautious as the flu can be fully cured without serious complications when diagnosed early.

Of the other four confirmed cases in Greece, two were from United States and the other two came back from Britain.
