In July 1988, an outbreak of cholera with 71 culture-confirmed cases of biotype El Tor, serotype Ogawa, occurred in a non-endemic area in Mae Sot district, Tak province. Fifty-two cases had diarrhea and 19 had asymptomatic cholera infection. No cases died. Epidemiological investigation revealed a significant association between cholera infection and the consumption of uncooked beef. Increased risk of cholera infection was observed when the incriminated beef was kept at room temperature and consumed later without cooking. The beef was possibly contaminated with V. cholerae O1 from an infected butcher who may have contracted the disease from his foreign worker who was found to have asymptomatic cholera infection. Early detection of the outbreak and rapid identification of transmission source permitted prompt appropriate control measures which, therefore, prevented the outbreak from spreading to other communities. As outbreaks of foodborne diseases, including cholera, have been reported frequently after the consumption of raw food in many parts of Thailand, preventive educational efforts should be directed towards modifying the traditional behavior patterns of consuming raw food among these Thai people.
1988年7月,泰国北碧府夜功县一个非霍乱流行地区爆发了霍乱,有71例经培养确诊的埃尔托生物型小川血清型霍乱病例。52例出现腹泻,19例有无症状霍乱感染。无病例死亡。流行病学调查显示,霍乱感染与食用生牛肉之间存在显著关联。当受污染牛肉在室温下保存后未经烹饪就食用时,霍乱感染风险增加。这些牛肉可能被一名受感染的屠夫所携带的霍乱弧菌O1污染,该屠夫可能是从其被发现有无症状霍乱感染的外籍工人那里感染了这种疾病。疫情的早期发现和传播源头的快速识别使得能够迅速采取适当的控制措施,从而防止了疫情蔓延到其他社区。由于在泰国许多地区,食用生食后经常报告包括霍乱在内的食源性疾病暴发,因此应开展预防性教育工作,以改变这些泰国人食用生食的传统行为模式。
