The virus (choice C) is the agent that causes the disease, and the vaccine (choice D) is a means of preventing the disease. The school (choice A) is not the host, but it may be the environment where the disease is spreading.

Correct Answer is ["A","D","E"]
Explanation
The correct answers are A, D, and E. Primary prevention activities aim to prevent the onset of disease or injury. Teaching a class about the risks of cigarette smoking and organizing a program to promote skateboard safety are examples of primary prevention activities. Lobbying for funding for health promotion efforts is also a primary prevention activity because it aims to prevent the occurrence of illness or injury in the community. Creating a plan of care for children who have a diagnosis of diabetes mellitus and recommending a seating arrangement for a child in a body cast are examples of secondary prevention activities, which aim to detect and treat health problems early to prevent complications.
