How Does Using Disinfectant Reduce the Spread of Disease?

Published in Disease Prevention 3 mins read

Using disinfectant reduces the spread of disease primarily by killing germs on surfaces.

Disinfectants play a crucial role in preventing illness by targeting harmful microorganisms like viruses and bacteria that can linger on frequently touched surfaces after cleaning. While cleaning removes dirt and some germs, it doesn't necessarily kill all of them.

Here's a breakdown of how disinfectants work to lower the risk of disease transmission:

Killing Germs on Surfaces

As highlighted in the reference, disinfecting after cleaning is key. Disinfectants contain chemicals specifically designed to inactivate or destroy pathogens.

  • Targeting Pathogens: Disinfectants break down the structure of bacteria and viruses, rendering them unable to reproduce or cause infection.
  • Interrupting Transmission: Many diseases spread when people touch contaminated surfaces and then touch their eyes, nose, or mouth. By killing the germs on the surface, disinfectants break this chain of transmission.

By killing germs on a surface after cleaning, disinfecting further lowers the risk of spreading germs that can cause illness. This step is essential for creating a safer environment, especially in areas with high traffic or potential for contamination.

Disinfecting vs. Cleaning

It's important to understand the difference between cleaning and disinfecting for effective germ control.

Action Primary Goal Effect on Germs When to Do It
Cleaning Removes dirt, grime, and germs Removes some germs (doesn't kill) Before disinfecting
Disinfecting Kills germs Kills most or all germs After cleaning, on clean surfaces

Cleaning is the necessary first step to remove visible soil and debris that can hinder the effectiveness of disinfectants. Disinfecting is the subsequent step that actually eliminates the microscopic threats.

Practical Steps for Effective Disinfection

To maximize the benefit of using disinfectants:

  • Clean First: Always clean the surface with soap and water or a general cleaner before applying disinfectant.
  • Read Labels: Follow the instructions on the disinfectant product label, including the recommended contact time (how long the surface must remain wet with the product).
  • Focus on High-Touch Surfaces: Regularly disinfect surfaces that are frequently touched by multiple people, such as:
    • Doorknobs and handles
    • Light switches
    • Countertops
    • Faucets
    • Remote controls
    • Keyboards and phones
  • Use Appropriately: Use disinfectants in well-ventilated areas and store them safely away from children and pets.

By consistently and correctly using disinfectants on clean surfaces, you significantly reduce the number of viable pathogens present, thereby further lowering the risk of spreading germs that can cause illness. This simple action is a powerful tool in preventing the spread of many common infectious diseases.
