Cypress, California (September 2020) – Dr. Hiroki Ohge, Professor, Department of Infectious Diseases, Hiroshima University Hospital, and a group of researchers lead by Dr. Takemasa Sakaguchi, Professor, Hiroshima University Graduate School of Biomedical and Health Sciences, have completed a research study that demonstrates that irradiation with filtered 222nm UV-C light effectively reduces SARS-CoV-2 in an in vitro experiment. This is the first study conducted in the world on the efficacy of 222nm UV-C light against SARS-CoV-2, the virus causing COVID-19.
In this study, Ushio’s Care222® UV-C disinfection* module was placed 24 cm above the surface of the plates in which the viral samples were placed. The radiation intensity at the surface of the plates was 0.1 mW/cm2. The study showed that 3 mJ/cm2 of 222nm light resulted in at least a 99.7% reduction of viable SARS-CoV-2 samples. The researchers concluded that the study demonstrated the effectiveness of 222nm UVC irradiation on SARS-CoV-2. The researchers further noted that the results suggest that the 222nm UVC technology could be used for infection prevention and control against COVID-19 both in occupied and unoccupied spaces.
Ushio’s Care222 device features a specially designed band pass filter that is based on groundbreaking research and technology developed by Columbia University and filters the longer UV wavelengths from the lamp.

Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.
Does not cause sunburn, skin cancer or cataracts
Ultraviolet rays with a wavelength of 222 nm are absorbed by the cornea of the stratum corneum of dead cells, so they do not cause damage such as sunburn, skin cancer, and cataracts.
Virus suppression / sterilization
Ultraviolet rays with a wavelength of 222 nm destroy the DNA / RNA structure of viruses and cells, and suppress and sterilize them.
A key advantage of the UV-based approach is that UV light is likely to be effective against all airborne microorganisms, in marked contrast to vaccination methods. For example, while the inactivation efficiency of UV light will almost certainly vary as different strains of influenza virus emerge, they are unlikely to be significant. Similarly, as multidrug-resistant variants of bacteria emerge, their UV inactivation capacity is unlikely to vary greatly.
The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics.
