Sneeze camera covid-19

The COVID-19 pandemic will have implications on the future of human race. The speed of contagion has ignited a sprint to get the latest information on the disease and its spread. Researchers at MIT have used high speed cameras to record the distance of a sneeze.  

Intro from article

The current coronavirus disease 2019 (COVID-19) outbreak vividly demonstrates the burden that respiratory infectious diseases impose in an intimately connected world. Unprecedented containment and mitigation policies have been implemented in an effort to limit the spread of COVID-19, including travel restrictions, screening and testing of travelers, isolation and quarantine, and school closures. A key goal of such policies is to decrease the encounters between infected individuals and susceptible individuals and decelerate the rate of transmission.

High speed camera capturing sneeze

Main points

  • Sneeze can travel upto 8m – 4 times the distance previously predicted
  • Used a high speed Phantom v2512 camera
  • Record at high speed 5 micron particles in a cough
  • Speed recorded upto 1 million fps

Summary and comment

Very useful use of high speed cameras to record these metrics. The high speed cameras not only can show the distance and speed, but can be used to work out the size of globules. This will give valuable insight in the usefulness of masks to reduce spreading.
