A Swiss-based company Viroblock SA has developed a novel face-mask containing technology that traps and kills over 99.9995% of H1N1 flu viruses (swine flu), 99.999% of H5N1 flu viruses (avian flu) and 99.997% human corona viruses on passing through the air. Aimed at helping to protect people from the respiratory pathogens, the mask is up to one hundred times more effective than a similar mask without Viroblock technology.With latest reports of as many as 55 people infected with Sars-like coronavirus in Saudi, killing 33 in total, and large numbers of Muslims expected to travel to Mecca during Ramadan and in October for the annual Haj pilgrimage, the technology can be used to assist in reducing the risk and incidence of airborne-transmitted infection.“Aerobiology tests for face-masks simulate real life situations, in which the user is exposed to viruses coming in. The mask helps prevent transmission from and to the person wearing the mask,” Viroblock CSO Dr Thierry Pelet commented.He explained that aerobiology tests, carried out in high security laboratories, create a mist of viruses on the outside of the mask, a pump is used to draw air and viruses through the mask, and finally testing for live virus occurs on the inside of the mask. “We believe that our protective face-mask can help protect healthcare, agriculture and security workers effectively, with added advantages of comfort of wear and easy identification,” Viroblock chief executive officer Dr Jamie Paterson said.
