What is a fomite in the context of infection transmission?

A living organism that transmits infection
A contaminated inanimate object
A type of bacteria
An infection caused by water

The correct answer is: A contaminated inanimate object

In the context of infection transmission, a fomite is defined as a contaminated inanimate object that can serve as a vehicle for the transmission of infectious agents. Common examples of fomites include doorknobs, utensils, medical equipment, and shared surfaces. When an individual touches a fomite that is contaminated with pathogens, they can subsequently transfer these pathogens to their mucous membranes (such as those in the mouth, nose, or eyes), leading to infection. Understanding the role of fomites in the transmission of infections is crucial for infection control practices, particularly in healthcare settings. Proper cleaning and disinfection of surfaces and objects can significantly reduce the risk of fomite transmission and help prevent the spread of infections.
