Monkeypox Virus 99.99% Neutralized Using Ultraviolet Tech on Surfaces

New study by biosafety technology company R-Zero yields crucial findings in the fight against virus


SALT LAKE CITY, UT – September 1, 2022As concern about the spread of Monkeypox heightens, the results of a new study being released today by biosafety technology company R-Zero find its UV-C tech is 99.996% effective in neutralizing the virus on surfaces.

The study, conducted by a third-party laboratory, measured the impact of R-Zero’s Arc device (which delivers hospital-grade disinfection using UV-C) against a Monkeypox virus surrogate, commonly studied in laboratories as a model poxvirus and almost identical to Monkeypox. The study found that at a distance of 8 feet, Arc demonstrated a 99.996% reduction in the surrogate after a single 7-minute cycle.

While harder to transmit from most surfaces, the Monkeypox virus can still pose a threat, lingering on surfaces for hours to days and can survive in linens, clothing and on environmental surfaces, particularly in dark, cool, and low humidity environments. This study makes it clear that certain UV-C tech can neutralize Monkeypox on most surfaces,” said Dr. Richard Wade, Chief Scientist for R-Zero, and a leading expert in toxicology and microbiological contamination.

R-Zero’s Arc uses hospital-grade UV-C to disinfect air and surfaces. The technology leverages 254nm UV-C light to destroy microorganisms’ DNA/RNA quickly and is currently being used in schools, hospitals, restaurants, senior communities and many industries throughout the United States.

About the study: The study was designed to simulate consumer use and was conducted by Microchem, a leading microbiology laboratory, following the modified procedures outlined in the American Society of Test Materials (ASTM) test methods for Standard Practice for Determining Antimicrobial Efficacy of Ultraviolet Germicidal Irradiation Against Microorganisms on Carriers with Simulated Soil (ASTM E3135-18).
