C
Vector-borne transmission
D
Fecal-oral transmission
Verified step by step guidance1
Understand the different types of disease transmission: Direct contact transmission involves physical contact between an infected person and a susceptible host, allowing pathogens to transfer directly.
Airborne transmission occurs when infectious agents are carried by dust or droplets suspended in the air and inhaled by a susceptible host, without direct physical contact.
Vector-borne transmission involves an intermediate organism, such as a mosquito or tick, that carries and transmits the pathogen from one host to another.
Fecal-oral transmission happens when pathogens in fecal particles pass from one host to the mouth of another, often through contaminated food or water.
Since contact with another person's blood requires physical contact for the pathogen to transfer, the most likely mode of transmission in this scenario is direct contact transmission.
