Which statement describes the contact mode of transmission?

• A. Vector-borne transmission by insects
• B. Vehicle transmission through water or food
• C. Airborne droplets that travel short distances
• D. Direct or indirect contact with an infected person or their discharges or contact with contaminated objects

Answer: (D)

Contact transmission happens when an infection spreads by direct touch with an infected person or their bodily discharges, or by touching objects or surfaces that have the infectious agent on them. This includes things like shaking hands with someone who is infected, or handling a contaminated doorknob and then touching your mouth or eyes. That’s why practices like hand hygiene, wearing gloves when appropriate, and cleaning surfaces are effective prevention. The other described modes involve different pathways: vector-borne spread uses insects to carry the pathogen; vehicle transmission occurs through contaminated water or food; and airborne transmission involves droplets or aerosols that travel through the air, often over greater distances.
