A lot of people have had the flu during the past two or three months.  I read one thing that is very important to keep from getting the flu is to wash hands often and use hand sanitizers.  Some businesses even give promotional hand sanitizers away.  Another thing that helps is to gargle daily either with mouthwash or warm salt water.  Even drinking hot drinks such as tea or coffee help because they move the virus germs out of the throat where they take hold.  Taking Ester-C and zinc plus other vitamins including D3, eating healthy meals, and getting plenty of rest is important, too.
