OSAKA — The Osaka prefectural board of education said Monday it will open an office to deal with the study needs of high school students from Neyagawa, Osaka Prefecture, being quarantined at Narita airport because they have swine flu.

The office will open at the end of the month, about 20 days after the first students became infected. Details about the office remain unclear.

"The students are concerned that being quarantined and away from school so long will cause them to fall behind in class when they return. We're considering what actions to take to ensure they get caught up," said Akio Mukaiazechi, a prefectural education official.
