Your phone is disgusting. Here's how to clean it | Lotti Tajouri
Summary
Molecular biologist Lati Tajuri argues that smartphones act as a "third hand" that re-contaminates washed hands, posing significant risks in healthcare and biosecurity. He shares research identifying thousands of microbes, including superbugs and quarantine pests, on phones used in hospitals and by international travelers. Tajuri proposes integrating UV-C sanitization stations into public hygiene protocols to treat phones with the same care as hands, ensuring comprehensive infection control.
