The current pandemic with the SARS-CoV-2 virus shows how important hygiene measures are to avoid its spread.
The effect of UVC on viruses
The virus information is contained in the capsid in the form of single-stranded DNA or RNA. Whether RNA or DNA, the mechanism of UVC destruction of these molecules is verye ective. The radiation penetrates the viral envelope and hits thegenetic material. As with DNA, RNA forms pyrimidine dimers and additional uridine hydrates. The information for reproduction is lost, the virus is no longer virulent and the infection cycle is broken.
