Nicole SharpSimulating a SneezeSneezing 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 <a href="https://doi.org/10.1063/5.0241346" rel="nofollow noopener noreferrer" target="_blank">“sneeze simulator”</a> 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.

Leisureguy<a href="https://mastodon.social/@augieray" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@augieray</a> A news report about the widespread incidence of long-term coughing (8 weeks or so) following an illness listed several possible illnesses that might cause such a thing: influenza, sinusitis, asthma, and whooping cough/pertussis. Not mentioned — *vividly* not mentioned, as in "elephant in the room" — was Covid.That seems clearly to be denial at work.<a href="https://globalnews.ca/news/10219029/persistent-cough-causes-treatment/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://globalnews.ca/news/10219029/persistent-cough-causes-treatment/</a><a href="https://mstdn.ca/tags/coughing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#coughing</a> <a href="https://mstdn.ca/tags/illness" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#illness</a> <a href="https://mstdn.ca/tags/covid" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#covid</a>
