We're taking a break from the usual Talk Evidence to focus on the new corona virus that has emerged in China. With a brand new disease, we have to build our evidence base from scratch - basic virology, epidemiology, pathogenicity, transmissibility, and ultimately treatment are all unknowns. In this episode of Talk Evidence, we're trying to get away from the headlines and talk about what we need to know - to hopefully give you some insight into these issues. (8.00) Peter Openshaw, professor of experimental medicine at Imperial College London, talks to us about the pathogenicity of covid-19 (17.30) Wendy Barclay, head of the Department of Infectious Disease at Imperial College London, describes what can change the R0 of a viral disease. (20.50) Raina MacIntyre, professor of biosecurity at the Kirby Institute at the University of New South Wales, talks to us about how effective masks are at preventing spread of viruses. (30.00) We discuss treatment options in the face of massive uncertainty.

Full Episode
Welcome back to Talk Evidence, your monthly roundup of the world of EBM. And I'm staging a little takeover this week. We're not doing the usual start, stop or anything. We're going to talk about coronavirus because I live in Brighton, which if you're outside the UK, you might not know, but seems to be the epicentre of coronavirus infection in the UK. We have doctor surgeries shut.
We have schools being shut. We have people being quarantined. So I want to know what is the evidence about how this is spreading, what the virus is and maybe treatment as well. As always, I'm joined by our two favourite EBM nerds. We've got Carl Hennigan and Helen MacDonald. Carl, can I get you to introduce yourself?
Yes, hi, I am Editor-in-Chief of BMJ Evidence-Based Medicine, Professor of EBM at the University of Oxford and a GP.
And Helen, you're joining us from Bath.
Yes, hi, I am Editor-in-Chief of BMJ Evidence-Based Medicine, Professor of EBM at the University of Oxford and a GP.
And Helen, you're joining us from Bath today because you are isolated but not with coronavirus. It's chickenpox. Can I get you to introduce yourself?
Yes, I'm Helen MacDonald, the UK research editor for the BMJ.
If we think about coronavirus from our nerdy EBM point of view, this is a really interesting time. This is a brand new virus that we don't know anything about, really. And so that evidence kind of ecosystem we talk about is just evolving at this point.
I agree. This is a very interesting time in the world of evidence-based medicine. As we're going to hear on the programme, you're going to have evidence from case reports. You're going to have evidence from a Cochrane review with case control studies and cohort studies, what we call low-quality evidence. We're going to hear about rapid reviews of evidence.
