Answer to Question 1

ANS: B
Frequently, the communicable period begins before symptoms are present. The communicable period, or communicability, follows latency and begins with shedding of the agent. The incubation period is the time from invasion to the time when disease symptoms first appear. Thus, even if parents kept their children away from the child with the fever, this could possibly be ineffective because their children may have already been exposed before the child exhibited symptoms. It is unlikely that the children suddenly changed schools. Although, there may be many reasons why parents keep their children home from school, in this situation there is a specific reason that can be identified.

Answer to Question 2

ANS: B
Knowing the reservoirs for infectious agents is important, because, in some cases, transmission can be controlled by eliminating the reservoir, such as eliminating the standing water where mosquitoes breed. The other interventions, not having events at dusk or dawn, providing bug repellent, and wearing bright colors are ways the tourists can cope with the mosquitos that are present, but they do not eliminate the breeding and presence of the mosquitos.
