UVC and Corona virus

Corona and the fight against infection are on everyone's lips. But what is up and down when we want to use UVC light to fight Corona.

Currently, there are several studies on the effect of UVC on Corona and a number of recommendations for what UVC dose is needed to achieve a given effect.

The first thing to be aware of is that some of the studies on Corona are NOT Corona CV-2, but studies on other types of Corona, which are referred to as similar to CV-2.

 

Not just Corona

Corona consists of many different types of viruses, and studies have shown that these are not the same in terms of the dose needed to inactivate viruses. E.g. Corona Sars is relatively well studied and has a 90% reduction at 240 J/m2. A common cold is also a Corona variant and has an inactivation dose of 7 J/m2 at 90%.

Not only is there a difference in the type of Corona being studied, but there is also a difference in the study methods:

  • How they are performed
  • What technique has been used to assess the effect

The results of laboratory tests with in vitro tests range from 30 J/m2 and up, and mucus testing by the RT-PCR method indicates up to 250 J/m2 as the required dose for a 90% reduction. As you can see, the required dose varies greatly.

 

Confused?

When we look at the Corona types that Corona CV-2 is similar to and the studies that have been performed which have a solid scientific background, they suggests that a dose around 37 J/m2 is a good solution for a 90% reduction. There are several studies that say you get a 99.9% reduction at that dose, but they were performed in an aqueous solution, where UVC has a better effect than on surfaces.

 

CleanMove3

In collaboration with Aarhus University, we developed our CleanMove3 to be able to disinfect auditoriums and living spaces upon discovery of the Corona infection. CleanMove3 can be moved around in locations where there is a need to disinfect surfaces before using the room again. CleanMove3 is a good option if you want a flexible solution that can solve your need for disinfection when it arises.
