The first new-flu group infections at a Tokyo school were confirmed, with nine students of a high school in Minato Ward contracting the disease, the Kyodo News reported on Thursday.

The privately run Seisoku High School will be closed for one week from Thursday due to the outbreak. All the infected students have no record of traveling abroad recently.

The nine students -- six boys and three girls -- have developed flu symptoms such as fever, but their conditions are stable, the report said.

The total number of people infected with the new H1N1 strain of influenza A in Japan reached 532 as of Thursday.
