Beijing has reported its first death case of A/H1N1 flu, also the fourth on the Chinese mainland, health authorities said Wednesday.

The patient, a freshman at the Beijing University of Aeronautics and Astronautics, had tested positive for A/H1N1 flu and died Tuesday, a spokesman with the Beijing Municipal Health Bureau said.

The young student and some other schoolmates developed fever and other flu symptoms during a military training -- a compulsory training for freshmen at Chinese universities -- in the past week in the Daxing District in suburban Beijing.

The student was sent to a district hospital Monday as the physical condition deteriorated, but died Tuesday.

More than 3,000 freshmen from the university attended the military training starting October 22, and 28 out of 71 who had a temperature above 38 degrees Celsius had tested positive for A/H1N1 flu, the health bureau spokesman said.

"The health and education authorities have ordered the university to enhance prevention measures and quarantine the patients. Currently, they are all in stable condition and no severe case has been reported," he said.
