Definitions in Infection Control
Understanding the distinctions between cleaning, disinfection, and sterilization is fundamental to maintaining hygiene and safety standards in clinical and environmental settings.
| Term | Definition |
|---|---|
| Cleaning | The physical removal of foreign material (such as soil, organic matter, or debris) from objects is typically accomplished using water with detergents or enzymatic products. |
| Disinfection | A process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects. |
| Sterilization | The complete elimination or destruction of all forms of microbial life, including highly resistant bacterial spores, is achieved through physical or chemical methods. |
High-Yield Clinical Point
Always remember that cleaning must precede disinfection or sterilization. Failure to remove organic debris (like blood or protein) can shield microorganisms, rendering subsequent disinfection or sterilization processes ineffective.
