Influenza, commonly known as the flu, primarily affects the respiratory system, leading to symptoms such as fever, cough, sore throat, body aches, and fatigue. It can cause significant illness, particularly in high-risk populations such as the elderly, young children, and those with underlying health conditions. In severe cases, influenza can lead to complications like pneumonia and can be fatal. Vaccination and antiviral medications can help mitigate its effects and reduce the spread of the virus.
