People with respiratory illnesses often exhale infectious particles. What is the size range of these “infectious respiratory particles”?
Infectious respiratory particles move through the air in what WHO calls a “turbulent puff cloud” — a mix of gases and respiratory particles from the lungs. What happens when this cloud slows down sufficiently?
The new WHO report identifies two ways infectious respiratory particles move through the air. The first is airborne transmission or inhalation. Where might the particles enter someone’s body in this scenario?
Another way that infectious respiratory particles can be transmitted through the air is “direct deposition.” What defines this mode of transmission?
Many factors influence how particles spread and their potential impact, including evaporation, environmental conditions, and speed of expulsion. Which of the following activities leads to a “more forceful expiration” in WHO’s terms?
If you’re exposed to an airborne pathogen, are you automatically infected?
Transmission of infectious respiratory particles is more likely indoors than outdoors. Why?
The new report states it’s not advisable to categorize particles into aerosols (smaller) and droplets (larger). Why is this?
