Should we continue wearing facemasks after July 19 Covid restriction lifting?

Boris Johnson has said it will be a matter of "personal responsibility" and transport operations and shops are likely to decide their own policy on the issue.

We put out a poll on our website early last week asking our readers if they will be wearing face masks after July 19 and 61 per cent of readers said "yes" compared to 39 per cent who said "no".

How are the rules on face masks changing?

Almost all remaining Covid restrictions will be removed on July 19 if the Prime Minister confirms the move this afternoon.

The legal requirement to wear a face covering is set to end but official guidance will say they should still be worn in some settings on a voluntary basis.

Nadhim Zahawi, vaccine minister, said: "The guidelines will be very clear on things like mask-wearing. There’s an expectation of people to wear masks indoors, in crowded places, on public transport.”

What do scientists say?

The British Medical Association, which represents doctors, says there should be "ongoing requirements" to wear masks in enclosed public spaces such as public transport, shops and healthcare settings.

Dr Mike Tildesley, from the University of Warwick and a member of the Scientific Pandemic Influenza Group on Modelling group, said there had been "mixed messaging" over face masks from the Government even in the last few days.

He said: “I think it’s quite confusing actually for people to know what the right thing to do is,” he said. “I think all that we can do is take a sort of appropriate approach where we look at the situation and sort of weigh up the risk ourselves and I hope that enough people do that going forward that we don’t see a big surge.”

Paul Hunter, professor of sociology at Nottingham Trent University, said: “The benefits of masks have always been uncertain because the quality of the evidence in both directions is so weak.”

However, Dr Luarance Aitchison, from the department of computer science at the University of Bristol , said: “Our research has shown mask-wearing reduces the spread of Covid-19 by around 25% if everyone wears them.”

Is there more evidence on the benefit of face masks?

Research suggests that face coverings worn over the nose and mouth reduce the spread of coronavirus droplets from coughs, sneezes and speaking.

One Royal Society report last summer found that the use of cotton masks was associated with 54 per cent lower odds of infection in comparison with the no-mask groups.

In another study, published in the Proceedings of the National Academy of Sciences, scientists calculated that wearing face coverings prevented more than 78,000 infections in Italy between April 6 and May 9 2020, and more than 66,000 infections in New York City over just a few weeks.

A report recently published by the Royal Society suggests that even basic homemade face coverings can reduce transmission if enough people wear them when in public.

What do people need to know about wearing masks?

Face coverings should be made of multi-layers of high quality cotton and people are advised to sanitise their hands before putting one on and removing it, and to wash masks daily.

When wearing a face covering, it should cover the mouth and nose, with no gaps.

Many experts believe face masks are better seen as part of a package of measures, which includes things such as social distancing.
