No one should leave the house without a face covering, a leading UK scientist has said.
Professor Sir Venki Ramakrishnan, president of the Royal Society, said the UK “way behind” many other countries in using coverings to protect against the spread of coronavirus.
He pointed to mounting evidence suggesting masks protect both the wearer and those around them.
Not wearing one should be considered “anti-social”, in much the same way as drink driving or failing to wear a seatbelt, Prof Ramakrishnan said.
“Not doing so increases the risk for everyone, from NHS workers to your grandmother,” he added.
