Covid-19 coronavirus

The newly discovered coronavirus SARS-CoV-2 causes the infectious disease Covid-19. It first appeared in December 2019 in the Chinese city of Wu-chan, but now it is spreading around the world.

The study proves: The UVC emitter eliminates the SARS-CoV-2 virus

A study carried out by the Tübingen University Hospital in Germany confirms that the SARS-CoV-2 virus, the causative agent of the COVID pandemic, can be neutralized by ultraviolet radiation. The device used for disinfection using UV radiation is also called a germicidal emitter. The study is unique in that it was not tested with just similar viruses, but with a real pathogen.

SARS-CoV-2 virus – How long will it survive on object surfaces?

The virus is not able to survive alone. It needs the host to reproduce its genetic material and produce new viruses. How long viruses can survive without a host cell depends on many factors. The ambient temperature, humidity, UV radiation, material composition and surface properties have a significant effect on this. Although the number of viruses decreases over time under all experimental conditions, studies also show that the materials remain infectious for very different times.

UVC radiation is not suitable as COVID-19 treatment

UVC radiation can kill bacteria and viruses, but is not suitable for treating Covid-19. Intense exposure to the sun or artificial UV radiation will not help fight the existing disease. The natural source of UVC radiation is the sun. It is completely filtered by the Earth's atmosphere, so it does not reach the Earth's surface. Artificially generated UVC radiation with a sufficiently high dose is used for disinfection. The disinfecting effect of sunlight on Earth has not been proven.
