The Evidence: Covid 19: Transmission and South America

06/13/20 • 49 min

Claudia Hammond and a panel of international experts look at the latest research into Covid-19, the disease caused by the new coronavirus which is sweeping through the world.

As the disease spreads how is South America handling the pandemic? How are the indigenous people of the Amazon protecting themselves? We also look at the aerodynamics of infection - if the air in an ITU room is changed 12 times and the virus still lingers what hope do offices have?

On the panel are Professor Lydia Bourouiba, Associate Professor at the Fluid Dynamics of Disease Transmission Laboratory at Massachusetts Institute of Technology, Dr Adam Kucharski from the London School of Hygiene and Tropical Medicine, Professor Holgar Schunemann, co-director of the World Health Organization (WHO) Collaborating Centre for Infectious Diseases, Dr David Collier, Clinical Director at Queen Mary University London and Barbara Fraser, health journalist in the Peruvian capital Lima.

Toothbrush

What is the most personal item you own - one you don’t want anyone else using?

For Katy Brand it’s her toothbrush. So how did the toothbrush become one of life’s essentials?

With the help of resident public historian of Horrible Histories fame, Greg Jenner, Katy goes back to ancient times, when the toothbrush was merely a stick. But the brush, as we know it, only came into being much later when a convict spied a broom in his cell and had a bright idea.

But how has ingenuity and innovation shaped the toothbrush and ensured its place in our lives? And given most are plastic, how environmentally friendly is the toothbrush’s legacy?

Featuring designer and toothbrush collector, Sophie Thomas, and advocate for clean teeth, Peter Dyer, Chair of Hospital Dentists at the British Dental Association.

High heel

Katy Brand loves a high heel. Once known by friends and family for her ‘shoe fetish’, her dad even gave her a ceramic heel that could hold a wine bottle at a jaunty angle.

These days, Katy’s cherished heels from her torture days live in her cupboard. She has traded the pain for the statement trainer. But their art, history and construction still fascinate her.

So what is it about the high heel that has made it stand the test of time?

With the help of resident public historian, Greg Jenner, Katy explores the heel’s fascinating passage through time, finding a place on the feet of men, as well as women, in high and low places. Heels donned the feet of men on horseback in 17th century Persia, were adored by King Louis XIV, and gained an erotic currency with the invention of photography.

But how has science and engineering ensured the high heel’s survival?

Footwear Technologist, Mike George, shows us how the high heel is engineered, and how he can test if a particular design is teetering on the edge of safety. Social scientist, Heather Morgan, reveals the perceived benefits of wearing heels, as well as the risks when she fell foul to when fell in heels and broke her ankle.
