Covid in schools: How risky are schools?

Why are schools staying open during the second lockdown in England?

The UK government has issued new guidance which means pupils and teachers in England's secondary schools and colleges must wear face masks, and says it wants to continue prioritising the wellbeing and long-term future of young people.

BBC health correspondent Laura Foster looks at where the riskiest parts of the school and some of the ideas being used to help stop Covid-19 spreading.
