Ministers have been warned by NHS bosses that advising people to wear facemasks to slow the spread of coronavirus risks jeopardising critical supplies to the health service.

Government scientists will examine the evidence about masks today before making a formal recommendation on whether the public should wear them.
The World Health Organisation is understood to be ready to issue fresh guidance on wearing masks in shops, on public transport and in other crowded spaces as part of measures to exit the lockdown.
NHS chiefs have raised concerns that advising people to wear masks as restrictions are eased could put their staff at risk amid a continued shortage of personal protective equipment.
Ministers have been urged not to recommend them to the public unless there is “clear evidence” that benefits outweigh the risk to the health service.
Chris Hopson, chief executive of the hospitals group NHS Providers, said: “If the government is going to consider advising the general public to wear facemasks it must fully assess the impact on the NHS. Fluid repellent masks for health and care staff are key to safety and to avoid the spread of coronavirus.
“Securing the supply of masks, when there is huge global demand, is crucial. This must be a key consideration. There needs to be clear evidence that wearing masks, along with other measures, will deliver significant enough benefits to take us out of lockdown to potentially jeopardise NHS mask supply.”
Last night Public Health England said that staff had the right to refuse to work in circumstances where they did not have safe equipment. At the daily Downing Street briefing, Yvonne Doyle, the agency’s medical director, was asked if she would “support their decision not to go in” if they did not feel safe.
She replied that people “have to make their decisions based on whether they are in a risky situation or not”. Scientists and doctors have called on ministers to back the use of homemade masks or non-clinical ones to avoid supply problems, something already recommended by US health authorities. However, there is concern that any endorsement of masks would encourage people to buy medical versions, which could send prices soaring.
While masks are not in short supply in hospitals, there are fears that that would change if they were recommended more widely. Hospitals are reported to be laundering and reusing single-use gowns up to three times and there are issues with the supply of other items such as respirator facemasks.
A government source said: “We are being guided by the science and there is an ongoing review of evidence, but the safety of the NHS and our NHS staff is our top priority.”
Sir Patrick Vallance, No 10’s chief scientific adviser, said last week that while there was “variable” evidence on whether masks slow the spread of the virus, it was “absolutely crucial that masks are available in hospitals”.
There is little good evidence that people can protect themselves by wearing masks, particularly without training in how to put them on and remove safely. However, there is better evidence that wearing masks can stop respiratory droplets reaching other people, leading to hopes that encouraging mass use could slow the spread.
Focus on the potential role of masks is likely to intensify as the WHO prepares to shift position and say that masks, including homemade ones, could have a role in tackling the virus as countries allow people to leave their homes.
The WHO presently says that “the wide use of masks by healthy people in the community setting is not supported by current evidence and carries uncertainties and critical risks” including “diversion of mask supplies and consequent shortage of masks for healthcare workers”. It is due to soften its tone and accept a potential role for masks given they are being widely used as a way out of lockdown.
The updated WHO advice will stop short of urging people to wear masks but will offer more detailed advice on using them.
Professor Trish Greenhalgh, of Oxford University, who has published an evidence review on masks, said homemade masks should be compulsory on public transport and in offices and shops. “Your mask doesn’t protect you but it protects other people,” she said. “A mask needs to be an item of clothing. It’s like a T-shirt, wear it and chuck it in the wash. Detergent kills Covid.”
She urged people to “make your own”, insisting: “No one should be wearing medical masks.”
While in Asian countries it has long been common to wear masks, they are increasingly being used as part of European exit strategies. The German state of Saxony has made them compulsory in shops and on public transport, and Spain is giving them out to commuters. In Italy 85 per cent of people say they wear masks in public, up from 26 per cent six weeks ago.
In Spain the figure has gone up from 5 per cent to 65 per cent, and in France from 5 per cent to 43 per cent, according to YouGov. In Britain 11 per cent are wearing masks, up from 1 per cent in early March.
