Blue light is effective against Hantavirus, Influenza A, SARS-CoV-2
Share
Did you know that strong antimicrobial blue light can help against lipid-enveloped viruses like Influenza A, SARS-CoV-2 and also Hantavirus?
These viruses have an outer lipid layer which is sensitive to oxidative stress and environmental damage. Studies have shown that 405 nm antimicrobial blue light can reduce the activity of viruses like SARS-CoV-2 and Influenza A. Spectral Blue MWHI technology uses high-intensity 405 nm and 450 nm blue light for continuous environmental disinfection without chemicals.
This gives an important extra benefit for places where people are close to each other and infection risks are higher. Examples are ambulances, isolation rooms, waiting areas, cruise ships and other closed spaces.
Unlike chemical disinfection, antimicrobial blue light can work also in areas where people are frequently present. This helps to lower microbial load all the time and supports normal hygiene routines.
Research on blue light disinfection is growing fast, and lipid-enveloped viruses like Hantavirus are now creating increasing interest for continuous light-based infection prevention technologies.
