Understanding Low-Touch Surfaces: Everything You Need to Know

Areas within indoor environments may experience different degrees of use, and this may result in different levels of bacteria and microorganisms. Here is what you need to know. 

Defining Low-Touch Surfaces

Understanding Low-Touch Surfaces_

Low-touch surfaces are objects that experience the least amount of contact in indoor environments.1 These can include surfaces like:


  • Walls,
  • Ceilings, and
  • Floors.   

    Low-touch surfaces are often compared to high-touch surfaces, or surfaces that are associated with more contact with people in indoor environments.

Low-Touch Surfaces and Microorganisms

Low-touch surfaces may seem like they are not areas at high risk of carrying bacteria and microorganisms. This, however, may not be entirely true – as different microorganisms have been associated with frequenting low-touch surfaces at substantial rates. 


For example , a 2022 University of California San Diego study3 determined the presence of detectable SARS-CoV-2 in three apartments:



Apartment Type of Surface Positive Negative Positive Percentage
A Low-Touch 17 36 32%
B Low-Touch 5 42 11%
C Low-Touch 19 35 35%

There is a way to improve the disinfection of low-touch surfaces, and this includes the use of Ultraviolet (UV) light.

UVD Robots for UV Disinfection

UVD Robots are a series of mobile, self-navigating UV disinfection robots produced by the Danish company Blue Ocean Robotics, a company that manufactures and develops mobile robots for the service industry.

These robots are self-driving and require minimal labor to distribute Ultraviolet C (UV-C) light to disinfect indoor areas. UVD Robots use 254 nanometer (nm) UV-C light in particular, a type of light associated with reducing:


  • Escherichia coli,
  • Candida Albicans,
  • Staphylococcus aureus, and
  • Clostridium difficile

    at greater than 3-log to greater than 6-log rates, representing a reduction efficacy of greater than 99.9% to greater than 99.9999%.2

    In this way, UVD Robots can eliminate the types of microorganisms found on some low-touch surfaces such as floors and walls, using 254 nm UV-C light - solidifying the practice of cleaning and disinfection.
