Investigation of a small series of cases of typhoid fever infected in a river between 1963 and 1970 revealed that all were caused by a single source, a carrier of a rare phage type of Salmonella typhi. The contamination of the river resulted from an incorrect sewage connexion with a surface water drain outfall into the river.
对1963年至1970年间在一条河流中感染的一小系列伤寒热病例的调查显示，所有病例均由单一来源引起，即一名携带罕见噬菌体类型伤寒沙门氏菌的携带者。河流污染是由于污水连接错误，地表水排水口排入河流所致。
