  • The new coronavirus has upended all of our usual calculus about seemingly ordinary activities.
  • And that’s another complicating factor in figuring out transmission: People emit virus particles in a range of sizes, and some are small enough to be considered aerosols, or fine particles that can stay suspended in the air for hours and can travel with air currents across tens of feet.
  • What’s not clear from this data is whether the virus is commonly transmitted via aerosols, or how long the virus remains infectious in aerosols in real-world settings.
