Understand the concept of direct contact transmission: it involves the physical transfer of pathogens from an infected individual directly to another person without any intermediate object or surface.
Identify examples of direct contact transmission: these include actions where there is direct physical contact between individuals, such as kissing, sexual contact, and shaking hands.
Recognize that touching contaminated surfaces is an example of indirect contact transmission, where pathogens are transferred via an object or surface rather than direct person-to-person contact.
Compare each option to the definition of direct contact transmission to determine which one does not fit the criteria.
Conclude that 'Touching contaminated surfaces' is NOT a way pathogens are spread through direct contact because it involves an intermediate object, making it indirect contact transmission.
