Hundreds of scientists across the world have a burning question for the World Health Organization.<br />According to Gizmodo, they just petitioned the WHO via an open letter with one demand.<br />The demand is that the WHO acknowledge publicly that the novel coronavirus behind COVID-19 can be airborne.<br />That means it can spread through the air (and linger there) via tiny aerosols emitted by the breath of infected people, not just large droplets.<br />The letter puts the WHO in a tight spot. That's because it's still difficult to know how often aerosol transmission of COVID-19 actually occurs.<br />Furthermore, the idea that a virus is either airborne or not may be an outdated concept.<br />On Monday, the WHO said its technical experts would review the letter and its recommendations.
