Question

Quizplus · Accepted Answer

The fact that several individuals became ill after attending the community picnic suggests that a common vehicle of transmission was involved. A common vehicle is a source of infection that is shared by multiple people, such as contaminated food or water. It is possible that the pathogen was acquired through indirect contact (such as touching contaminated surfaces) or vector transmission (such as through insect bites), but the fact that multiple people were affected suggests a common source of contamination. Airborne transmission is also a possibility, but it is less likely in a picnic setting where people are outdoors and not crowded closely together.
