Join our George Cross campaign for NHS staff
We are urging Sun readers to sign a petition calling for our NHS staff to be awarded the George Cross.
We are backing a proposal by Lord Ashcroft to honour our health heroes with the gallantry gong given for acts of bravery that did not take place in battle.
A No10 spokesman said: “The NHS is doing a fantastic job and the nation will want to find a way to say thank you when we have defeated this virus.” SAS hero Andy McNab added: “The award of a George Cross would show an emotional appreciation.”
We are asking our readers to please sign the petition below.
eBay sells a variety of surgical face masks too.
A range of other sites, including Bioide, are also supplying masks to the public and various companies - yet be sure to check the masks have the necessary certification.
Should I be wearing a face mask?
Some single use masks can be sterilized in the oven to make them good to go again and save you money.
You can also make your own mask from common household items that is as effective as most of the ones on the market.
Surgical masks for general public use is debated because they can become contaminated by other people's coughs and sneezes or when putting them on and removing them, but it beats nothing.
The government's scientific advisers are reviewing whether or not to make mask-wearing mandatory.
They are expected to reach a verdict soon - it's best to wait and see what they say first, before stocking up on masks which could be used by people who really need them.
It is also recommended that only healthcare workers should be wearing the most protective N95/FPP2 and FPP3 masks.
How to wear the N95 face mask
Most masks will come instructions, but they must cover your nose and mouth to avoid breathing in any virus particles.
Once you have placed the mask over your nose and mouth, use the straps to tighten around your head so it fits snugly on your face.
Fitting could become a problem with facial hair, including a beard, as research has shown that even a day's beard growth can allow air to flow inside the mask.
To check if it fits properly, a negative check requires you to place both hands over the mask - making sure not to move the mask - and breathe in sharply.
If the mask pulls in towards your face and there are no air leaks around your nose and eyes, then it is fine - otherwise adjust the straps and nose placing.
The positive test is the same, but you breathe out, making sure any extraction valve is covered with your hands.
No air should leak out around your nose and eyes, or you will need to adjust the straps and nose placing.
If either check fails, repeat once you have corrected the mask.

Cheaper face masks made by reusable cloth are also not recommended and could increase chances of infection.
Public Health England has warned that masks are only effective if used properly.
A spokesperson said: "Facemasks must be worn correctly, changed frequently, removed properly, disposed of safely and used in combination with good universal hygiene behaviour in order for them to be effective.
"Research also shows that compliance with these recommended behaviours reduces over time when wearing face masks for prolonged periods."

What are N95 masks?
N95 masks are disposable face masks that are proven to filter the air to an industrial standard.
Manufacturers vary, but the N95 is a stamp from the US National Institute for Occupational Safety and Health to show that it is efficient, which comes with a logo.
They are used to stop you from breathing in hazardous small particles, such as dust, mould or aerosol paint particles.
They generally have an eight-hour shelf life before becoming clogged depending on the work you're doing.
