HANOI (Vietnam) - AN official says a school in southern Vietnam has closed after 26 teachers and students tested positive for swine flu.

Tuong Nguyen Su, head of personnel at Ngo Thoi Nhiem high school in Ho Chi Minh City, says 24 students and two teachers have the virus.

Mr Su says the school closed Monday and will remain so for at least a week. He says more than 100 students and about 40 teachers are quarantined there.

Mr Su says the virus spread after a student was infected by his uncle visiting from the United States.
