Aitch-oo

"Bless you", or some variant thereof: Certainly in English, I'd say this...

https://en.wikipedia.org/wiki/Response_to_sneezing

I had no idea how different the responses were to #sneezing -- and yet they all originate (mostly) from the Black Death.

In England, the classic rhyme of:

Ring-a-ring o' roses,
A pocket full of posies.
A-tishoo! A-tishoo!
We all fall down!

Springs to mind: https://en.wikipedia.org/wiki/Ring_a_Ring_o%27_Roses

It's surprising how the simple act of #sneezing still has these connotations.

I'd love to hear more from anyone who's interested in this. :)

Simulating a Sneeze

Sneezing and coughing can spread pathogens both through large droplets and through tiny, airborne aerosols. Understanding how the nasal cavity shapes the aerosol cloud a sneeze produces is critical to understanding and predicting how viruses could spread. Toward that end, researchers built a “sneeze simulator” based on the upper respiratory system’s geometry. With their simulator, the team mimicked violent exhalations both with the nostrils open and closed — to see how that changed the shape of the aerosol cloud produced.

The researchers found that closed nostrils produced a cloud that moved away along a 18 degree downward tilt, whereas an open-nostril cloud followed a 30-degree downward slope. That means having the nostrils open reduces the horizontal spread of a cloud while increasing its vertical spread. Depending on the background flow that will affect which parts of a cloud get spread to people nearby. (Image and research credit: N. Catalán et al.; via Physics World)
