COVID-19 is a global pandemic that has required a global response. In this week’s episode Matthew Weait talks to Dr Michael Schmuker, reader in data science at the University of Hertfordshire, who joined the Global Consortium of Chemosensory Researchers early in the pandemic to research the link between loss of the sense of smell and COVID-19. Find out how their work led to loss of smell becoming a recognised COVID-19 symptom and how their work is helping to improve our understanding of the virus.
