|Influenza is a viral infection that is caused by the flu virus. It is spread from person to person via the secretions of the nose, throat and lungs. This infection causes symptoms such as a fever, sore throat, cough, headache muscle aches fatigue and weakness. Flu usually only lasts a few days, but if left untreated can result in pneumonia and more severe respiratory disorders. Many Americans (approximately 226,000) are hospitalized yearly because of influenza.
One of the most effective ways to prevent flu is with an influenza vaccination. The best time to get a flu vaccine is every fall between October and November so that you are immunized against strains that have developed since the previous year. Influenza tends to occur from November through May, but during January and February, most episodes of influenza are reported.
The influenza vaccine is readily available at drug stores, your local health practitioner as well as on-site flu clinics. There are differences between a conventional flu vaccine (which uses the crude live form of the virus) and a natural flu vaccine (which does not use the crude live form of the virus).
