Between June 23 and June 30, 1973, 90% of 650 passengers and at least 35% of 299 crew members experienced a diarrheal illness during a 7-day Caribbean cruise aboard a passenger cruise liner. Symptoms were consistent with shigellosis, and Shigella flexneri 6, Boyd 88 biotype, was isolated from rectal swabs taken from 8 to 35 ill passengers and 33 of 294 crew members. Epidemiologic evidence incriminated the ship's water, including ice, as the probable vehicle of transmission, and elevated coliform counts were found in potable water samples obtained aboard the vessel at the peak of the outbreak. Potential sources of contamination of the vessel's potable water supply were investigated, and improvements in the loading and chlorination of potable water were recommended.
1973年6月23日至6月30日期间，一艘载客游轮在为期7天的加勒比海航行中，650名乘客中有90%以及299名船员中至少35%出现了腹泻疾病。症状与志贺氏菌病相符，从8至35名患病乘客以及294名船员中的33人采集的直肠拭子中分离出了福氏志贺氏菌6型，博伊德88生物型。流行病学证据表明，包括冰块在内的船上用水可能是传播媒介，在疫情高峰时从船上采集的饮用水样本中发现大肠菌群数量升高。对船上饮用水供应的潜在污染源进行了调查，并建议改进饮用水的装载和氯化处理。
