With coronavirus cases in the UK now in the thousands, fears about the spread of the virus are now widespread. Early symptoms include a cough and headache, making it tricky to know if you’ve been infected or if you simply have a common cold.
Now, scientists from Bauhaus University in Weimar have revealed exactly what happens when we cough, and why it’s wise to stay home even if you don’t think you have the virus.
The team filmed a man coughing using a method called the Schlieren Method, which reveals air flow in incredible detail. In the video, the man can be seen coughing in six ways - normal breathing, coughing, coughing into hand, coughing into sleeve, coughing into a dust mask and coughing into a medical mask.
