In the April 1, 1907 edition of The Evening World, reporters identified Mallon as a "walking typhoid fever factory." A day later, their rival the New York American described Mallon as a "Human Typhoid Germ." The original use of the term was more descriptive than pejorative because doctors and other investigators actually did not know the name of Mallon and used "Typhoid Mary" as a means to refer to a "Mary" who had typhoid.
Even with such headlines that referenced Mallon as a bacteriological entity (for example, a walking typhoid fever factory, a human typhoid germ, a living human culture tube, etc.), newspapers described Typhoid Mary in terms of a sanitary-bacteriological-synthesis.
