20. Thomas M. England, private, Hospital Corps, was born in Chillicothe, Ohio, and served in the Army from January 6, 1899, to January 5, 1914, in the grades of private, acting hospital steward, and sergeant, first class, Hospital Corps. (..) He volunteered and underwent the fomites experiment, sleeping 20 nights in infected bedding, for which experiment he received a donation of $100 from the Cuban funds allotted by General Wood for these experiments.

Alternatively, such fluids may be transferred from soiled hands to fomites, or airborne organisms may impinge or settle onto fomite surfaces. Fomites may also serve as a site for the replication of a pathogen, as in the case of enteric bacteria in household sponges or dishcloths.

Fomites play a significant role in the transmission of infectious agents. The list of fomites is seemingly endless and includes objects in common use,(..)Toys are fomites and contribute to illness in children wherever the toys are shared.
