COVID-19: What you need to know about the coronavirus pandemic on 20 May

1. How COVID-19 is impacting the globe

2. Why the world’s recovery from COVID-19 could be doughnut shaped

An economic model shaped like a doughnut is being embraced by Amsterdam as a way to help both people and the planet thrive.

The model, developed by Kate Raworth, a senior research associate at Oxford University’s Environmental Change Institute, is a way of achieving societal goals and thinking about economics based on the priorities set out by the United Nations Sustainable Development Goals.

Those in the middle of the doughnut fall short of life's essentials while those in the ring around that centre occupy a sweet spot where the Earth's resources aren't exploited. Everything outside the doughnut overburdens the planet.

Such sustainable models have never been more important, said Raworth. "As we all start thinking about how we will emerge from this crisis, let us seek to be holistic in how we reimagine and recreate the local-to-global futures of the places we live,” she says.

3. What’s the latest on coronavirus antibody tests?

A new antibody test has been approved by the UK after an independent evaluation showed it had a high degree of accuracy and specificity. The test can pinpoint COVID-19 antibodies thanks to a "specificity greater than 99.8% and sensitivity of 100%”. The test, developed by Roche, is one of a number approved for use around the globe.

Antibody tests check blood for certain proteins produced by our bodies’ immune systems. These tests have been identified by a number of countries as a way to tackle the spread of the virus and loosen lockdowns since they can show who has been exposed to the disease.

4. COVID-19 computer game teaches children importance of social distancing

A new computer game called "Can You Save the World?" was designed to help children better understand social distancing, according to Reuters.

The game was designed by university psychology professor, Richard Wiseman, and involves players navigating a busy street to avoid pedestrians, cyclists and people sneezing. "There's quite a lot of research showing that if you get people - kids in particular - to behave in certain ways in video games it really does transfer to real life," Wiseman said.
