What term describes a mode of transmission where pathogens are transmitted via fomites?

The correct response is based on the understanding that "indirect contact" refers to the transmission of pathogens through surfaces or objects known as fomites, rather than person-to-person contact. When a person touches an object that has been contaminated with infectious agents—such as doorknobs, shared utensils, or medical equipment—those pathogens can then be transferred to a new host.

This mode of transmission emphasizes the importance of cleaning and sanitizing surfaces to prevent the spread of infections, particularly in healthcare and community settings. By recognizing how indirect contact facilitates the spread of pathogens, individuals can take appropriate precautions, such as washing hands frequently and ensuring that surfaces are disinfected, to help reduce the risk of infections.

The other modes of transmission mentioned in the question, such as direct contact and airborne transmission, involve different mechanisms whereby pathogens spread, focusing either on physical touch between individuals or through the airborne route. Common vehicle transmission refers to pathogens being spread through a single contaminated source affecting multiple people, such as food or water. Each mode highlights different aspects of infection control, but in the context of fomites, indirect contact is the most accurate description.
