Swine Flu

Swine flu is an infectious respiratory disease caused by influenza A viruses that originally circulated among pigs but can sometimes infect humans. The term is most commonly associated with the Influenza A (H1N1) virus responsible for the 2009 influenza pandemic. Swine flu spreads primarily through respiratory droplets released when an infected person coughs, sneezes, or talks. Symptoms typically include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue, and sometimes vomiting or diarrhea. Most cases are mild and resolve with supportive care, but severe illness can occur, particularly in young children, older adults, pregnant women, and individuals with chronic medical conditions. Diagnosis may involve laboratory testing, and antiviral medications such as oseltamivir may be used in certain cases. Annual influenza vaccination remains one of the most effective methods of prevention.
