TOKYO — Japan confirmed its first three swine flu cases Saturday.
The two teenage boys and a teacher arrived at Tokyo's Narita International Airport on a flight from Detroit after visiting Canada on a school trip, Health and Welfare Minister Yoichi Masuzoe said in a televised news conference.
The three tested positive for swine flu at Japan's National Institute of Infectious Diseases.
Forty-nine other passengers who returned to Japan on the same flight and sat near the patients have been taken to a facility near the airport, where they will be monitored for 10 days.
