In-Room Airborne Transmission of COVID-19
Despite the fact that large droplets of about five microns to 10 microns can travel a distance of more than one meter before settling on a surface, tiny droplets can evaporate and leave and leave behind particles virus known as aerosols hanging in the air. A study conducted recently revealed that can remain active on a surface for up to three hours after being released. WHO had initially ruled out any possibility of spreading COVID-19 through aerosols but later reversed its position.
The World Health Organization admitted that there is substantial evidence concerning in-room transmission of COVID-19. This implies that indoor air quality plays a big role in reducing the rate of airborne transmission. In addition, the United States Disease Control and Prevention (CDC) confirmed that asymptomatic patients are able to transmit the virus at close range.
