The impetus to the splendid series of investigations which culminated in the recognition of the important role which carriers play in the dissemination of typhoid fever was given by Koch1 in 1902. Basing his conclusions upon the findings collected by the Typhoid Commission of Trier, in the course of the preceding nine months, he expressed the belief that the propagation of typhoid fever took place essentially through the transference of the corresponding organisms from individual to individual, and that while infected drinking water could unquestionably produce the disease, infection of the water by a typhoid individual must inevitably precede and that a non-infected even though bad water in itself can have nothing to do with the production of the malady. He maintained that in the past too much emphasis had been placed upon the possibility that certain periodical outbreaks of the disease--notably in so-called typhoid houses and typhoid districts--might have been due to the activity of typhoid organisms which had been lying dormant possibly for years, in soil and ground water, and which then through water-courses had found their way into the drinking-water supply and thus brought about the outbreak. As a matter of fact, the origin of many outbreaks, notably those of a local character, seemed in those days so completely wrapped in obscurity, that the assumption of a possible latent existence of the organism, viz., an existence outside of the human body, did not appear unwarrantable, even though unsupported by tangible evidence.
