A new survey says many people haven't changed their hand washing habits in light of the H1N1 flu outbreak.

The survey was done by the Bradley Corporation of Menomonee Falls, a manufacturer of bathroom and locker room furnishings.

It found 54 percent of the respondents said they "wash their hands no more or less frequently" in public restrooms as a result of the virus. It also found that 87 percent of respondents wash their hands after using public bathrooms, but one percent of those only rinsed with water.
