Answer:
C. 3 indirect transmissions
Explanation:
In epidemiology, direct transmission is considered to occur when an individual has direct contact with a pathogen, which infects him and develops a disease. Indirect infections, on the other hand, occur when individuals come into contact with the pathogen through a transmission vehicle.
In this case, we can conclude that in the question above, there were 3 cases of indirect transmission. This is because all people who had contact with the pathogen, established that contact through the contaminated marker. In this case, the marker is a transmission vehicle.
