    Default Study Shows UV light kills Covid

    Researchers offer first proof that Ultraviolet C light with a 222 nm wavelength — which is safer to use around humans — effectively kills the SARS-CoV-2 virus.

    Study shows first proof that a safer UV light effectively kills virus causing COVID-19 | Hiroshima University

    A study conducted by Hiroshima University researchers found that using Ultraviolet C light with a wavelength of 222 nanometers which is safer to use around humans effectively kills SARS-CoV-2 — the first research in the world to prove its efficacy against the virus that causes COVID-19.
    Other studies involving 222 nm UVC, also known as Far-UVC, have so far only looked at its potency in eradicating seasonal coronaviruses that are structurally similar to the SARS-CoV-2 but not on the COVID-19-causing virus itself. A nanometer is equivalent to one billionth of a meter.

    If the common availability of such light sources is there, that might actually be a useful discovery.

    A step forward indeed but the researchers themselves point out that this was an in vitro study only. 30 seconds of UV light 24cm (9") above a flat plate is a long way from waving a light around the inside of a subway train and having it be disinfected.

    Maybe everyone in airplanes can wear sunglasses as the interior is bathed in UV. Might fade the upholstery and plastics though.

    UV in a vigorous air-circulation system might work well.

    In widespread use already.

    The duration of exposure necessary to kill CV19 is problematic.

    Viruses are similar to each other. Some DNA or RNA inside a protein coat. One would expect that UV light or any other treatment would work equally on any virus.
