They recently published their results in the Journal of Photochemistry and Photobiology B: Biology. SARS-CoV-2 was also viable for several days on common surfaces, such as stainless steel and plastic.īecause of the urgent need to find effective disinfection methods for SARS-CoV-2, researchers from Tel Aviv University in Israel - in collaboration with the University of Haifa, Oranim Academic College, and Chaim Sheba Medical Center at Tel HaShomer - set out to investigate whether or not irradiation using UV LED would inactivate human coronaviruses. It was also measurable in poorly ventilated or crowded spaces. It is well known that SARS-CoV-2, which is the virus that causes COVID-19, can spread through respiratory droplets and surfaces contaminated by nasal, mouth, and eye secretions.Īccording to a review article in the journal Environmental Research, SARS-CoV-2 was present in air samples from areas such as hospital rooms and elevators.
