Beth Mole, writing for Ars Technica, on how Dyson hand dryers spread viruses in bathrooms:
Researchers have long known that warm air hand dryers can launch bacteria into the air—compared to dabbing with paper towels, which unleashes virtually none. But new jet air dryers, made by Dyson, are significantly more problematic—they launch far more viruses into the air, which linger for longer periods of time and reach much farther distances, researchers recently reported in the Journal of Applied Microbiology. This is particularly concerning because viruses, unlike many infectious bacteria, can easily maintain their infectiousness in the air and on surfaces, and just a few viral particles can spark an infection.
