What is one example of a fomite?

A doorknob serves as a prime example of a fomite, which is an inanimate object that can carry and transfer pathogens. Fomites play a critical role in the transmission of infections because they can accumulate microbes from hands, respiratory droplets, or other sources. When a person touches the doorknob, they can pick up any infectious agents present on its surface, and if they subsequently touch their face, mouth, or other surfaces, they may unknowingly spread the pathogens.

In a healthcare setting, the understanding of fomites is essential for implementing effective infection control measures, such as routine cleaning and disinfection protocols to minimize the risk of infection transmission. The other options—bed sheets, exam tables, and surgical instruments—are also fomites and can transmit infections; however, the selection of a doorknob underscores a common object found in various environments that frequently comes into contact with numerous individuals, amplifying its potential as a vector for pathogens.
