In just over 100 days, a new coronavirus has taken an unprepared world by storm, infiltrating every corner of the globe, sending entire nations into lockdown, killing thousands and infecting countless more. Across the world, governments are scrambling to react, hospitals are struggling to cope and an increasingly anxious public are starting to panic. The world's media is awash with data, information and misinformation. But what are the facts? What is COVID-19 and why is this strain of coronavirus so dangerous? What happens in our bodies when the virus attacks? How does this compare to previous pandemics? What do all the the numbers really mean, and how can data modelling help us look for an exit strategy? This programme investigates the scientific facts and figures behind the biggest public health crisis in living memory, and explores the latest research from the frontline of the medical and scientific fightback.

Xand van Tulleken, Raksha Dave and John Sergeant discover the parallels of the Great Plague of 1665 with the Covid-19 pandemic. Ch1. Outbreak The epidemic is traced back to its source in the parish of St Giles in the Fields, now at the heart of London's theatre district. The program also examines the symptoms of the disease and uncovers new research into the plague bacteria that could overthrow accepted ideas about how the infection was spread. Ch2. Decimation Xand heads to St Barts hospital to look back at historical records which show that nursing staff stayed behind and risked their lives to help the sick. Elsewhere, John investigates why infection rates were so different between the rich and poor, examining clothes typical for each group in the 17th century. Ch3. Aftermath Xand visits Samuel Pepys' parish church and discovers the sad tale of the Poole family, who within 11 days lost all five of their children. He also heads to Eyam in Derbyshire, revealing the heroic story of self-sacrifice that saw all 700 villagers lock themselves in to try to stop the disease from spreading to surrounding areas. Raksha Dave trials 17th-century disinfection methods and reveal a surprising substitute that can be just as effective as modern antibacterial cleaners.

When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
