Meanwhile, the number of people who had been in close contact with the patient rose to 77 in Guangdong, the commission said. Among them, 64 have been quarantined while 13 others, including 11 passengers on a bus boarded by the man, have remained out of contact. None of the quarantined has showed any abnormality.
