Sneeze simulator shows spread of invisible bugs | A coughing, sneezing, 3D-printed model of the human nose and upper airway has provided researchers with a better understanding of how airborne infections are transmitted. The knowledge will aid in developing effective ways of reducing that spread.
A coughing, sneezing, 3D-printed model of the human nose and upper airway has provided researchers with a better understanding of how airborne infections are transmitted. The knowledge will aid in developing effective ways of reducing that spread.
To that end, researchers from the Universitat Rovira i Virgili (URV) in Spain have designed and built a 3D model of the human upper airway and nasal cavity that is capable of simulating coughing and sneezing to better study the spread of disease-carrying particles. This dispersal pattern, the researchers say, increases the risk of infection spread to people in close proximity, as particles are likely to land directly on them, especially during face-to-face conversations or in shared environments. “These results help us to understand how particle nuclei are dispersed in indoor spaces and, consequently, how diseases are transmitted through the air,” said Nicolás Catalán, a researcher at URV’s Department of Mechanical Engineering and the study’s lead author.
