Direct contact transmission occurs by which means?

Direct contact transmission occurs by which means?

• A. Touching another person by shaking hands or other physical contact.
• B. Touching a contaminated surface only.
• C. Breathing in aerosols.
• D. Drinking contaminated water.

Answer: (A)

Direct contact transmission happens when a pathogen moves directly from an infected person to a susceptible person through physical touch. Shaking hands or any other direct physical contact is a classic example because the transfer occurs in the absence of an intermediate object or medium. Touching a contaminated surface involves a fomite and is an indirect form of transmission, not direct contact. Breathing in aerosols relates to airborne or droplet spread, which is through the air rather than direct person-to-person touch. Drinking contaminated water is a vehicle- or waterborne route, not direct contact between people. So direct physical contact best fits direct transmission.
