Ten more graduate students have come down with a mysterious pneumonia attack at Konkuk University's Seoul campus on Thursday, bringing the total to 31.
Twenty-one people were diagnosed with the same symptoms earlier. But all have so far tested negative for a dozen well-known infectious diseases.
"We're still trying to figure out the cause," a spokesman for the Korea Centers for Disease Control and Prevention said Thursday.
The school said all patients are graduate students at the school of veterinary science and most have mild symptoms.
Twenty-three are in isolation at state-run hospitals, while eight with very mild symptoms are quarantined at home. All have tested negative for Brucellosis, Q fever, and Legionella, which were among the prime suspects of the mysterious infection. They also tested negative for bacterial diseases like Mycoplasma and Chlamydia and viruses like Middle East Respiratory Syndrome and flu.
Meanwhile, it has emerged that the SK Group conducted recruitment exams on the campus last Sunday, when the outbreak was probably already underway.
Authorities asked 500 people who took the exams to report to the KCDC if they have symptoms like high fever.
