New finding from CDC: The US Centers for Disease Control and Prevention updated guidance on its website to say coronavirus can commonly spread “through respiratory droplets or small particles, such as those in aerosols,” which are produced even when a person breathes. “There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes),” the page now says. “In general, indoor environments without good ventilation increase this risk.”
