Students who will be graduating this year from China's top Peking and Tsinghua Universities are the first university students to return to school. They will resume classes after a one-week and two-week medical observation period respectively.

Peking University says its students in other grades will come back in late July and catch up with missed classes afterwards.

In Tsinghua, which neighbors Peking University, 400 students have returned to campus and are being kept under medical observation in two specially prepared dormitory buildings.
