There have recently been over 100 cases of Swine Flu reported in the U.S. The single best way to prevent the flu is to get vaccinated each year, but common sense habits like covering your mouth when you cough and washing your hands often can help stop the spread of germs and prevent illnesses like the flu. There are also flu antiviral drugs that can be used to treat and prevent the flu.
DISCLAIMER: The Centers for Disease Control have advised that in certain circumstances, the use of face masks in combination with other actions such as frequent hand washing, covering coughs, and avoiding crowded settings may help protect you from the swine flu, as well as decrease the likelihood of transmission of the disease to others. However, none of these actions alone or in combination, can prevent you from contracting or transmitting the Swine Flu. For further information on the best approach to protect yourself from the spread of flu, consult with your doctor and review the information on the Centers for Disease Control website at http://www.cdc.gov.
