Cover furniture with cloth to reduce COVID-19 risk: researchers
Laying porous materials over hard surfaces cuts virus survival time, say Indian 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.
