On Friday afternoon, staff with the National Health and Family Planning Commission arrived in Taojiang to help deal with the outbreak.
According to the local government, the school has about 3,000 students. Of the infected ones, 25 are in the same class. All infected students are those expected to sit the national college exam soon.
Zeng Shengda, with Taojiang's disease control and prevention center, said that the first infection occurred in January. Between February and July, another five students came to the center for examination and treatment. On August 6 and 8, three more students sought treatment at the center.
"The patients that came before July did not reveal they were students," Zeng said.
In August, the county government launched screening for all the students in the school.
The provincial and county authorities are still investigating the cause of the outbreak.
