Influenza (Flu)

Influenza, also known as the flu, is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can lead to mild to severe illness and, in some cases, even death. The flu season typically lasts from October to March, and symptoms include fever, cough, sore throat, muscle aches, and fatigue. Getting a flu vaccine each year is the best way to prevent the flu and its potentially serious complications.
