RAZOR: Do runners and cyclists spread COVID-19? The aerodynamics of a virus
David Bamford

Lockdown restrictions are easing around the world, but with the threat of subsequent outbreaks of COVID-19, more and more people are trading in public transport for personal travel. And it's breeding an army of avid walkers, runners and cyclists. 

But even when you're jogging by yourself you could still be interacting with the novel coronavirus: air is invisible to us and so are viruses. So, to visualize how COVID-19 could spread through air, scientists have been using 'computational fluid dynamics' and mathematical equations to predict how air actually flows.

RAZOR's Shini Somara speaks to Professor Bert Blocken from Eindhoven University of Technology in the Netherlands about his research mapping the flow of the particles we breathe out to see how they are affected by rapid movement.
