The bureau says sixteen students at Nanhu Zhongyuan Primary School in Chaoyang District were found to have high temperatures, seven of which were diagnosed with the A/H1N1 flu.

Eighteen students were absent from class on Monday. 12 of them, who are from four classes in two grades, developed a fever.

Another four students were struck with a high temperature the next day. Their test results have yet to be released.

A total of 154 students, teachers and parents who had close contact with the seven students have been put under medical observation.
