  However, experts say a lot of people do not follow it.
  A recent study found that many Americans fail to wash their hands after using public toilets.
  More than 95% of Americans questioned said they always wash their hands after using public restrooms.
  However, the study found that only 67% of them actually do so.

  Judy Daly works for the group.
  She admits that hand washing may seem an unusual subject to study.
  But she says hand washing is a very serious issue.

  Shaking hands with another person also can spread infection.

  Among the most common infections spread by hand are colds, influenza 3 and throat and ear infections.
  In addition, millions of food poisoning cases each year are blamed on people who prepare food who do not wash their hands.
  More serious diseases like cholera and hepatitis are spread this way, too.
  Many patients in hospitals also get infections. Some die from them.
  The spread of infections often is blamed on health workers who do not wash their hands after treating patients.
