Cover furniture with cloth to reduce COVID-19 risk: researchers
Covering steel, glass and wooden furniture in hospitals and offices with cloth will slow the spread of COVID-19, an Indian study suggests.
Earlier research found that the virus remains active for a longer time on impermeable surfaces.
In the new study, researchers found that once respiratory droplets disappear, a thin liquid film remains over the exposed solid area that serves as a medium for virus survival.
That thin film evaporates much faster on porous surfaces, they noted in a report published Wednesday in Physics of Fluids.
