It's one simple step that will help stop the spreading of bacteria and diseases.
Today is Stop! Clean Your Hands Day.
The Grey-Bruce Health Unit is hoping to get the message out to the entire public, but especially to health care workers.
Spokesperson Kristaina Simkins says it's important for those in the health care field to make sure they are washing their hands before dealing with a patient, and afterward to protect themselves.
Research shows 220 thousand people in Canada suffer infections every year, killing up to 12 thousand people.
Improved hand hygiene could potentially reduce those infections by 50 per cent.
Furthermore, Simkins says 30 per cent of the general public does not wash up after going to the bathroom.
She says that can cause problems because in our day-to-day work we come into contact with many people and handle many items, so germs can easily spread.
Simkins says it's important to make sure you're washing properly as well.
She says it's best to use warm water and soap, and to scrub your hands, in between your fingers, your cuticles and up to wrists for 10 to 20 seconds, and then to dry your hands with a paper towel.
There will also be a display and videos set up at the Health Unit's Owen Sound office all day with education for parents, kids, and health care professionals.
