Seasonal flu is a contagious viral illness that can cause severe complications, particularly in vulnerable groups like children, the elderly, and those with weakened immune systems. The flu is caused by the influenza virus, primarily types A and B, and spreads through respiratory droplets. Symptoms include fever, cough, sore throat, and body aches. Treatment focuses on rest, hydration, over-the-counter medications, and, in some cases, antiviral drugs. Preventive measures, such as annual vaccination and good hygiene, are crucial.
