How long does coronavirus stay in the air after someone with COVID leaves the room?
It took two years for the WHO to admit covid is airborne. The reason is rooted in science history
Covid, it’s now an established fact, is airborne. Though aerosols and droplets may sound similar, their public health implications are very different. The assumption that covid was spread by droplets informed public health advice such as stressing the importance of social distancing, wearing any kind of mask including cloth ones, and disinfecting surfaces—as opposed to focusing on high-quality masks that can stop aerosol transmission (such as N95s) and ventilation.
