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.

There are currently 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 part of the studies of Corona, are NOT Corona CV-2, but studies of other types of Corona, which are referred to as similar to CV-2.

 

Not just Corona

Corona is many different types of viruses, and studies have shown that these are not the same in terms of the amount of dose needed to inactivate viruses. Eg. 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 made
  • 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 has up to 250 J/m2 as the required dose for a 90% reduction. Therefore, there is a big difference in required dose.

 

Confused?

When we look at the Corona types that Corona CV-2 is similar to and the studies that have been done with a good scientific background, it 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 are made in aqueous solution, where UVC has a better effect than on surfaces.

 

CleanMove3

We have developed our CleanMove3 in collaboration with Aarhus University, to be able to disinfect auditoriums and living spaces, at the discovery of 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 suggestion if you want a flexible solution that can solve a need for disinfection when it arises.
