CLEANING AND DISINFECTION


Why is it important?

Frequent cleaning and disinfection helps to prevent the spread of germs that may cause illness.

What is it?

Cleaning is an important first step because it physically removes dirt, organic matter and most germs from surfaces, but does not destroy some harmful germs that may remain. All surfaces must be thoroughly cleaned before disinfection. This ensures that germs are not hidden from the disinfectant when it is applied.

Disinfection is the process that destroys most disease-causing germs that remain on surfaces.

How often should it be done?

  • Routinely - for frequently touched surfaces; shared surfaces/items
  • More often - when illness levels have increased
  • Immediately - when surfaces are contaminated with blood or body fluids
