Which signs describe influenza (the flu)?

• A. History of respiratory infection with fever and productive cough
• B. Sudden onset of fever and chills (102-104), severe headache (photophobia), severe muscle aches and pains, cough (substernal burning), worst symptoms last 3-7 days but drag weeks
• C. Tachypnea and chest tightness with productive cough
• D. Wheezing and shortness of breath with fever

Answer: (B)

Influenza is best recognized by an abrupt, widespread illness with high fever, severe body aches, and a prominent headache, along with cough and fatigue. The described pattern—sudden high fever (102–104 F), intense muscle aches, severe headache (sometimes with photophobia), and a cough, with the worst symptoms lasting several days but fatigue lingering for weeks—fits influenza more closely than other respiratory illnesses. Other signs listed point more toward bronchitis, pneumonia, or reactive airway issues: rapid breathing with productive cough suggests a lower airway infection or obstructive disease; wheezing with fever fits asthma or bronchitis; a history of respiratory infection with fever and productive cough can indicate bacterial bronchitis or pneumonia. So the symptoms described align with the classic influenza presentation.
