Question

Quizplus · Accepted Answer

The common cold and flu are both caused by viruses. The common cold is mainly caused by rhinoviruses, although other viruses such as coronaviruses and adenoviruses can also cause cold symptoms. Influenza, on the other hand, is caused by orthomyxoviridae viruses. Therefore, the correct pair of viruses responsible for these diseases is rhinovirus-orthomyxoviridae. Choice A is the only one that matches this pair. Choice B is incorrect because enteroviruses do not cause cold or flu symptoms, and retroviruses are not associated with either of these diseases. Choice C is incorrect because flaviviruses are not associated with the common cold or flu, and rhinovirus is only one of the viruses that causes cold symptoms. Choice D is incorrect because neither poxviruses nor papillomaviruses are associated with the common cold or flu.
