The flu is a contagious respiratory illness caused by influenza viruses that can cause fever, cough, sore throat, runny nose, and body aches. It is spread through contact with respiratory droplets from an infected person when they cough, sneeze, or talk. Avoiding the flu can be achieved through various preventive measures, including proper hygiene, vaccination, and lifestyle modifications.
Getting vaccinated annually is one of the most effective ways to prevent the flu. The flu vaccine contains inactivated or weakened influenza viruses that stimulate the immune system to produce antibodies against the virus. These antibodies can then protect the body from infection or reduce the severity of symptoms if infected. Regular handwashing with soap and water for at least 20 seconds, especially after being in public places or coming into contact with someone who is sick, can also help prevent the spread of the flu virus. Using alcohol-based hand sanitizers when soap and water are not available can also be effective.
