目的：方法：调查2001年某餐馆发生霍乱疫情的原因、规模和传播途径。方法：调查对象为在该餐馆就餐、确诊为霍乱病人、有腹泻症状的人员和缝纫工人。对直肠拭子进行问卷调查和微生物检测。在这些病例中，通过分析餐馆菜单调查了316份食物历史。结果：2001年韩国报告了139例霍乱确诊病例。其中104起与餐馆有关。从地区来看，庆尚北-做发病率最高，为91例。在这91例病例中，74例在餐厅摄入食物，2例为员工，3例为家庭内继发感染病例。对316名曾在该餐馆进食的人进行的比值比分析结果如下：三明治5.07（95% CI，1.85-14.59），豆腐2.45（95%CI，1.09-5.56）、面条2.34（95%CI，1.24-4.42）、清蒸鱿鱼2.01（95%CI，1.17-3.47）和醋米饭1.82（95%CI，1.08-3.09）。可以肯定的是，这家餐厅是2001年爆发疫情的原因。结论：我们怀疑不止一名餐厅员工污染了餐厅供应的食物。此外，餐厅员工因食用从浦项渔业购买的生鱼而受到感染。这些生鱼本身有可能被海中的霍乱杆菌污染。
Objectives : This study was carried out to investigate the cause, magnitude and transmission route of the cholera outbreak in 2001 Methods : The study population were those persons who ingested foods at the restaurant, were confirmed as cholera patients, had symptoms of diarrhea and sewed as workers at the restaurant. A questionnaire survey and microbiological examinations on the microbes isolated from rectal swabs were conducted. Of the cases, 316 food histories were surveyed by an analysis of the restaurant menu. Results : There were 139 confirmed cases of cholera reported in Korea in 2001. Of these, 104 were related to the restaurant. By region, Gyeongsangbuk-do had the highest incidence with 91 cases. Of these 91 cases, 74 had ingested foods at the restaurant, 2 were employees and 3 were secondary infection cases within the families. The results of the odds ratio analysis of the 316 persons having ingested foods at the restaurant were as follows: sandwiches 5.07 (95% CI, 1.85-14.59), soybean curd 2.45 (95% CI, 1.09-5.56), noodles 2.34 (95% CI, 1.24-4.42), steamed squid 2.01 (95% CI, 1.17-3.47) and vinegared rice 1.82 (95%, CI, 1.08-3.09). It was certain the restaurant in question was the cause of the 2001 outbreak. Conclusions : We suspected that more than one restaurant employee contaminated foods served at the restaurant. In addition, eating raw fishes purchased at the Pohang Fisheries infected the employees of the restaurant. There is a possibility that these raw fishes were themselves contaminated by cholera bacilli in the sea.
