Coming into contact with another person's blood or saliva allows pathogen transmission via which of the following routes?

• A. Direct contact transmission
• B. Fomite transmission
• C. Airborne transmission
• D. Vector-borne transmission

Answer: (A)

Verified step by step guidance

1. Understand the definition of each transmission route: Direct contact transmission involves physical contact between an infected person and a susceptible host, allowing pathogens to transfer directly.
2. Recognize that fomite transmission occurs when pathogens are transferred via contaminated inanimate objects, not through direct bodily contact.
3. Recall that airborne transmission involves the spread of pathogens through droplets or dust particles suspended in the air, not through direct contact with blood or saliva.
4. Know that vector-borne transmission requires an intermediate organism, such as an insect, to carry the pathogen from one host to another.
5. Conclude that since coming into contact with another person's blood or saliva involves direct physical contact, the correct transmission route is direct contact transmission.
