Influenza, commonly referred to as the flu, is a respiratory condition that is highly contagious, report doctors at the Centers for Disease Control (CDC). The flu is caused by an influenza virus that is passed from person to person through droplets from the mouth and nose that are propelled in the air by coughing and sneezing. Touching an object that holds the drops such as linens, cooking utensils and doorknobs also can spread the virus. Using influenza prevention information is the best way to avoid the flu.
Vaccine
Vaccines are available annually in the fall during the height of flu season and are recommended by the CDC. Special vaccines such as the H1N1 flu vaccine available in 2009 can help protect against new viruses as they occur.
Washing
Hand washing is important during flu season. Washing hands often with soap and water or with alcohol-based hand lotions can kill the viruses picked up from other carriers.
Cover
Sneezes and coughs should be covered at all times with a tissue. The tissue should be discarded immediately to avoid spreading any germs.
Touching
Avoiding touching the face can help prevent the flu. As a general practice, keeping fingers and hands away from the mouth and nose is a good way to keep the virus from entering the respiratory system.
Avoidance
Avoiding people and places known to be infected with the flu will help to reduce the risks of picking up the influenza virus. Crowds, hospital waiting rooms and doctors' offices are particularly dangerous places that often are filled with people who carry the flu virus.
Healthy eating
Doctors at the Mayo Clinic report that people who eat a healthy diet can maintain a strong immune system. Poor diet and lack of sleep makes the immune system more vulnerable to contracting the flu.
