Washington, D.C. - We've heard it a million times - wash your hands.
But for some people, it's just not sinking in.
A recent survey by The Soap and Detergent Association shows more than a third of us seldom or never wash our hands after coughing or sneezing.
The same survey of more than one-thousand people also shows nearly 70% do not wash their hands long enough to get rid of germs or dirt.
Doctor Trish Perl, an epidemiologist at Johns Hopkins Hospital in Baltimore, says keeping your hands clean is "the single most important thing you can do" to prevent the spread of disease.
Perl adds that companies can not only save money, they can make their work environment cleaner and safer just by having hand sanitizers readily available.
