Influenza, or the flu, is a viral infection of the respiratory system that typically causes more severe symptoms, a sudden onset, and a higher risk of complications than a common cold.
The flu primarily spreads through respiratory droplets produced when infected individuals cough, sneeze, or talk. These droplets can be inhaled by others or contaminate surfaces.
Common symptoms include fever, body aches, headache, fatigue, cough, sore throat, and a runny or stuffy nose. Nausea, vomiting, and diarrhea can also occur, especially in children.
The most effective prevention is getting an annual flu vaccine. Other measures include frequent hand washing, avoiding touching your face, and staying home when sick.
