从1979年12月至1982年1月的26个月内,对急性腹泻患者1,097例进行了大便检查,对被查出大肠杆菌的624例进行毒素产生试验,从24例中分离出肠毒素性大肠杆菌。在24例中有2例是海外罹患病例,另1例被认为是由于海外旅行腹泻患者所引起的继发感染。21例,在发病前数个月内无海外渡航经历,推测可能是在国内感染而发病。 During the 26 months from December 1979 to January 1982, 1,097 patients with acute diarrhea were stool examined and 624 of the detected E. coli were challenged with toxin production, 24 of which were isolated for enterotoxigenicity Escherichia coli. In 24 cases, 2 cases were overseas, and the other 1 case was considered due to secondary infection caused by overseas travel diarrhea patients. In 21 cases, there was no overseas ferry experience within a few months before the onset of the disease, suggesting that it may be caused by an infection in the country.
