What type of transmission includes pathogen spread through close physical contact?

The type of transmission that involves the spread of pathogens through close physical contact is classified as direct transmission. This method of transmission occurs when an infected individual transfers pathogens directly to another person without any intermediate objects or vectors involved. Examples include touching, shaking hands, kissing, or any other form of physical interaction where pathogens can be transferred from one person to another.

In scenarios involving direct transmission, the pathogen must be able to survive briefly outside the host environment until it is transmitted to a new host. This form of transmission is significant in the spread of many infectious diseases, especially those that are highly contagious. Understanding this concept is crucial for effective infection control and prevention strategies in healthcare and community settings.
