As we ease out of lockdown, understanding how the COVID-19 pandemic is progressing across England is essential. How many people have been infected and where? How does our body fight the virus?

We’re talking a lot about testing in the media, and this is the best tool we have to help us understand the situation and make decisions about how we tackle the virus.

Join Dr Christina Atchison as we talk all things testing, from antigen (swab) tests and home testing kits to how we check how well they work and how easy they are to use. Ask questions, listen in and go behind the scenes with our COVID-19 Response Team.
