What is a fomite?

A fomite refers to any inanimate object or surface that can carry infectious organisms and serve as a vehicle for transmission. This includes items such as doorknobs, utensils, and countertops, which can become contaminated with pathogens and subsequently infect individuals who touch them. Understanding the role of fomites is essential in infection control and prevention strategies, as it highlights the importance of cleaning and disinfecting surfaces to reduce the spread of diseases.

Fomites are distinct from microorganisms themselves, which are the actual pathogens that cause infection. They also differ from infectious diseases, which are the illness caused by these pathogens. Furthermore, while cleaning substances can help eliminate pathogens from fomites, they are not considered fomites themselves. Recognizing the function of fomites is crucial for effective public health measures and disease management.
