Which mode of transmission involves a fomite?

The mode of transmission that involves a fomite is indirect contact. Fomites are inanimate objects that can carry infectious agents and facilitate their transmission from one individual to another. When a person touches a contaminated surface such as doorknobs, utensils, or medical instruments, they can pick up pathogens that may be present on that object. If that person then touches their mouth, nose, or an open wound, they can potentially introduce the pathogens into their body, leading to infection.

In contrast, direct contact involves immediate physical transfer of pathogens from one host to another, such as through touching, kissing, or sexual contact, without the involvement of an inanimate object. Airborne transmission refers to the spread of pathogens through aerosolized particles in the air, while vector-borne transmission involves the transfer of pathogens through living organisms, typically insects such as mosquitoes or ticks, which act as carriers to transmit diseases. Understanding these modes of transmission is crucial for implementing proper infection control practices in healthcare and community settings.
