However, in the early twentieth century, the advent of germ theory shifted the focus of public health from sanitary reforms to the laboratory. This changed the outlook of public health officials leading to alterations in the treatment procedures of the disease which were now concentrated mainly on the elimination of bacteria causing the disease.

A very good example to support this change is the stand taken by the officials to eliminate typhoid fever during the end of the nineteenth and the early twentieth century. Since typhoid had been established as a water- and food-borne systemic bacterial infection, officials mainly concentrated on sanitary reforms to curb the disease. Though these efforts considerably reduced the number of cases of typhoid fever, they could not completely eliminate the disease. With the increase in bacteriological studies in the early twentieth century, it became evident that healthy people could carry the Salmonella typhi bacteria in their excreta and could cause the spread of typhoid. These individuals were termed as “healthy carriers” because though they appeared healthy, they could still cause the disease to spread. (Leavitt, J.W.,1992)
