On Google, one of the most-searched questions related to the coronavirus is: “Can it spread through the air?” The answer? Yes. It is possible. World Health Organization (WHO) officials have said it is possible for COVID-19 to spread in the air under certain conditions. One of these conditions is poor indoor ventilation. Ventilation is the movement of air through a space, especially an indoor or enclosed space. We also describe ventilation as “air flow.” Experts say poor ventilation may help the coronavirus stay in the air longer. Fresh air, scientists note, break up virus droplets. And this reduces the chances of transmitting, or spreading, COVID-19. The Environmental Protection Agency (EPA) in the United States says that good “ventilation with outside air can help reduce airborne contaminants, including viruses, indoors.” Such findings are changing safety requirements for workplaces.
