All bacteria and viruses tested to date (several hundred over the years) include other coronaviruses and respond to UV-C disinfection.
UV light, specifically between 200 and 280 nm, inactivates (i.e. kills) at least two other close relatives of COVID-19:
- SARSCoV-1 (result of SARS);
- MERS-CoV (Responsible for the Middle Eastern Respiratory Syndrome).
COVID-19 infection can be caused by contact with contaminated surfaces, then touching the mouth, eyes and nose.
Minimizing this risk is a necessity because Sars-Cov-2 can stay up to three days on plastic and steel surfaces.
