A primary school in Beijing confirmed seven more A/H1N1 flu cases Saturday, including six students and one teacher, the municipal health bureau said.

As of 10 p.m. Saturday, 28 students and one teacher at the Nanhu Zhongyuan Primary School in Chaoyang District are all in stable condition, according to the bureau.

The school reported seven cases Wednesday, 10 Thursday and five Friday.

The mass infection was caused by a housekeeping servant, Fang Laiying, director of the municipal health bureau, said late Thursday.

The flu outbreak has forced the school to start the summer vacation a week ahead of schedule.

The primary school has 941 students and 78 teachers.

The Chinese capital reported 192 A/H1N1 flu cases as of 10 p.m. Saturday, among whom 124 have recovered and have been discharged from hospitals.
