    According to research, a new type of UV light makes indoor air as safe as outdoors

    Disinfection of indoor air with remote UVC light is a new way to safely and effectively destroy airborne viruses in occupied spaces. Research has suggested that remote UVC light from ceiling-mounted lamps could be a highly effective passive technique to reduce the infectivity of airborne diseases and reduce the risk of a subsequent pandemic. “Far-UVC…

    COVID-19 infection can be detected in breath tests: Study

    The study was published in Influenza and Other Respiratory Viruses. A new study showed that a few breaths are enough to detect viral residues in small droplets of liquid. This immediately leads to assumptions about possibly replacing unpleasant nasal swab tests with convenient and easy breath tests. Emilia Viklunddoctoral student of occupational and environmental medicine…

  • Research shows that face masks halve the distance of airborne pathogens

    Research shows that face masks halve the distance of airborne pathogens

    The findings are important because airborne viral pathogens, such as SARS-CoV-2, can be encapsulated and migrated through liquid droplets and aerosols formed during human respiratory functions such as speaking and coughing. Knowing how to reduce this spread can help keep people safe and manage the response to pandemics such as COVID-19, which have led to…

    Washing and drying reusable fabric masks does not affect their filtering ability: Research

    A study published in the journal Aerosol and Air Quality Research also confirms a previous study that layering a cotton mask on top of a surgical mask — suitable for the face — provides more protection than fabric alone. “That’s good news for sustainability,” said lead author Marina Vance, assistant professor Paul M. Rady Department…

    Wearable monitoring of COVID-19 biomarkers

    Results from 37 people diagnosed with COVID-19 revealed evolutionary forms of these parameters at all stages of the disease, from initial diagnosis to hospitalization and final recovery at home. Systematic imaging studies show a correlation between cough, speaking and laughing time and intensity, and total droplet production as an approximate indicator of the likelihood of…
