Ans: B
Feedback:
One distinguishing feature of influenza is the rapid onset, sometimes within minutes, of profound malaise. As with many viral respiratory tract infections, transmission is by aerosol or direct contact. In the early stages, the symptoms of influenza often are indistinguishable from other viral infections—fever, chills, malaise, muscle aching, headache, profuse watery nasal discharge, nonproductive cough, and sore throat. Persons with chronic rhinosinusitis complain of a constant pounding headache.
