Chinese people must keep wearing masks ‘for at least another year’ to stop the spread of COVID-19

People in China must keep wearing face masks ‘for at least another year’ to fend off the killer bug, Beijing’s top coronavirus expert has warned.

Zhang Boli, a medical specialist who was appointed by Beijing to supervise the country’s coronavirus response, asserted that wearing face coverings should become a norm for Chinese citizens even when the outbreak is contained.

‘I think the face masks will not be taken off for at least another year, at least this time next year. [We] definitely need to be prepared,’ Zhang told state broadcaster CCTV Saturday.

Zhang’s warning comes as fears of a second wave of the outbreak are fuelled after clusters of infections have recently emerged across the country.

The Traditional Chinese Medicine expert was invited to speak on ‘Kai Jiang La’, an educational youth programme aired on state broadcaster CCTV Saturday.

When asked about if people can stop wearing face masks during summer, Zhang predicted that the face-coverings would become a regularity for the foreseeable future.

‘At the moment, it looks like the coronavirus does not have many correlations to temperatures,’ Zhang told the presenter. ‘You see, in places like Indonesia and India, where the temperatures are quite high, there are still a lot of infections.

‘Even if the outbreak is contained, I think [we will] still need to wear face masks. [We] really have to adopt such habit.’

The health official asserted: ‘I think the face masks will not be taken off for at least another year, at least this time next year. [We] definitely need to be prepared.’

Not wearing masks is a ‘big mistake’, top Chinese expert says

Multiple Chinese experts have backed the claims that wearing face masks is effective in stemming the coronavirus outbreak.

Other Asian countries, such as South Korea and Singapore, have also adopted the measure to prevent the pathogen from taking hold.

George Gao, director-general of the Chinese Center for Disease Control and Prevention, told Science in an interview: ‘The big mistake in the U.S. and Europe, in my opinion, is that people aren’t wearing masks.

‘This virus is transmitted by droplets and close contact. Droplets play a very important role – you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth.

‘Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others.’

Dr Zhong Nanshan, Beijing’s chief medical advisor on the coronavirus, said that the mandatory order for everyone to don a face mask was one of the reasons China managed to contain the outbreak.

As China slowly moves toward a post-virus era and citizens return to their normal life, officials have required residents to continue wearing face masks regularly in public places as a precaution against the deadly disease. 

Other countries – including Austria and Italy – have made it compulsory to wear masks while shopping or using public transport, while those living in the Czech Republic and neighbouring Slovakia must wear masks whenever they go out.

Meanwhile, Dr David Nabarro, special envoy for COVID-19 at the World Health Organisation (WHO), suggested during an interview in April that ‘some form of facial protection is going to become the norm’. 

Although the British Government initially told the public that there was ‘no evidence’ to support healthy people wearing them, a Cabinet source has suggested that covering up with a face mask may be a requirement for everyone returning to work once lockdown is lifted.

Zhang’s remarks come as China has largely brought the virus under control as it has lifted lockdowns and restrictions across the country.

But the country has been on edge about a potential second wave after new domestic infections have recently emerged in cities across China – including the former epicentre Wuhan.

The city of Wuhan, where the pandemic began, has screened a total of 335,887 citizens for COVID-19 as of today, according to Wuhan Health Commission.

A total of six confirmed cases have been recorded in Wuhan on May 10, prompting the former ground zero to conduct a 10-day mass-testing on its 11 million residents since May 14.

The cities of Jilin and Shulan, located in the north-eastern Chinese province of Jilin bordering Russia and North Korea, have been under lockdown for over a week after reporting a local cluster of infections with 34 confirmed cases all linked to the same source.

Shulan, a city of 600,000 people, has tightened quarantine measures today by banning residents from leaving their homes in compounds with confirmed or suspected COVID-19 cases. 

Jilin, the capital city of Jilin province, also sealed off one of its districts yesterday after changing the area’s emergency level to ‘high-risk’.

China currently has 84 active domestic infections and 45 imported cases, according to official figures. The country’s tally of confirmed cases now stands at 82,954 and the death toll is brought to 4,634.  

So, which face masks will actually keep you safe?

HOMEMADE MASK

WHAT IS IT? From vacuum cleaner bags to sanitary towels and scarves, look online and you will discover that just about anything can be turned into a mask.

COVID-19 EFFECTIVE? A 2013 Public Health England study looked at the suitability of various household materials that could be used as masks to filter bacterial and viral aerosols — and vacuum bags came out well.

Aim for multiple layers — U.S. researchers found that a double layer of tightly-woven cotton with a thread count of at least 180 was one of the best barriers.

WHERE CAN I GET ONE? Search your house and see what’s already there.

SURGICAL MASK

The surgical mask (stock image)

WHAT IS IT? The disposable mask that you see surgical staff wearing. These 3-ply masks are fluid-resistant and prevent infected droplets from the surgical staff entering the respiratory system of the patient.

COVID-19 EFFECTIVE? Thin surgical masks protect from large airborne droplets, but won’t block very small particles that may carry the virus. Once wet their efficacy is reduced, which is why they are disposable. But they are considered to offer better protection than a cloth mask.

WHERE CAN I GET ONE? In short supply. The advice is that medical masks should be saved for medical professionals. We found a box of 50 for £65.99 on medisave.co.uk.

DIY STORE DUST MASKS

WHAT IS IT? Dust masks and other disposable face masks all look similar, but levels of protection against particles that can pass through vary. If it says FFP1 then it’s a basic kind of dust mask (picture left).

COVID-19 EFFECTIVE? More protection than a surgical mask (only if it fits well). But with the lowest level of filtration for this kind of respirator mask (to meet European standards, they have to be able to filter at least 80 per cent of particles) it can’t filter out tiny particles associated with viruses and bacteria.

WHERE CAN I GET ONE? Normally at DIY stores from £1 a mask. Your best option is seeing if a local independent DIY store has stock and delivers.

CYCLING MASKS

WHAT IS IT? Neoprene anti-pollution masks. They contain an air filter to stop cyclists breathing in pollution in heavy traffic. But they are not regulated to the same standard as medical masks so protection levels can vary.

COVID-19 EFFECTIVE? While they are untested regarding coronavirus, they are intended to provide a layer of protection from airborne particles. Some are marketed as N95 or N99 grade (the U.S. equivalent to the European regulation rating: Filtering Face Piece, or FFP), which refers to airborne particles filtered — 95 or 99 per cent.

WHERE CAN I GET ONE? UK brand Cambridge Mask Company is taking pre-orders (pictured). Cycling masks are available from Amazon.

THE FFP3 mask

Medical-grade FFP3 mask (Stock image)

WHAT IS IT? Another respirator mask that eliminates even more small airborne particles than the N95/FFP2. FFP3 masks draw air through a filter embedded in the fabric that catches almost all airborne particles.

COVID-19 EFFECTIVE? Short of being a full-on gas mask affair, this is the best protection as long as it fits correctly. The mask blocks out 99 per cent of airborne particles.

WHERE CAN I GET ONE? In short supply, you can normally buy one at Wickes for under £3. The next step up is a heavy-duty reusable respirator used when spraying paint or chemicals — but not comfortable to wear all day.
