Coronavirus: N95s offer the best protection, study says

coronavirus n95s offer the best protection study says

We’ve all been told to wear face masks to reduce the spread of coronavirus, but it turns out the material your mask is made of may affect your risk, a new study suggests. 

An N95 mask, which filters out nearly all particles both large and small, reduced the odds of transmitting COVID-19, the disease caused by the virus, the most.

But some masks were actually worse than not wearing a mask at all because they turned large potentially infected droplets into smaller droplets than can linger in the air longer.

The team, from Duke University, says the findings provide evidence that not all face masks are created equally and can give Americans advice on what to and not to wear when going out in public.  

Researchers tested 14 different types of masks and found that N95s (#14) were the best followed by three-layer surgical masks (#1) and various cotton masks (#4-10 and #13)

For the study, published in the journal Science Advances, the team looked at 14 different types of face coverings.

Researchers cut a hole in front of a black box so a speaker can talk into it and covered it with a thin sheet of light from a laser beam.

Next, they placed a cell phone camera in the back.and recorded the respiratory droplets that cut through the laser beam when they talk.

A person spoke towards into the hole saying the phrase ‘Stay healthy, people’, while wearing the different types of coverings. 

This included:  

 1. Three-layer surgical mask

2. N95 mask with exhalation valve

3. Knitted mask 

4. Two-layer polypropylene apron mask

5. Cotton-polypropylene-cotton mask

6. One-layer Maxima AT mask

7.  Two-layer cotton, pleated style mask

 8. Two-layer cotton, Olson style mask

 9.  Two-layer cotton, pleated style mask

10.  One-layer cotton, pleated style mask

11. Gaiter type neck fleece

12. Double-layer bandana

13. Two-layer cotton, pleated style mask

14. N95 mask, no exhalation valve, fitted

Results showed that N95 masks, which are designed to prevent 95 percent of particles from getting in or out, were the most effective.

Knitted masks and bandanas provided very litter protection while wearing a neck fleece was worse than no mask because it turned large droplets into smaller droplets (above)

Three-layer surgical masks and homemade cotton masks, which people made at home, also prevented particles from getting out. 

Cotton face coverings ‘provided good coverage, eliminating a substantial amount of the spray from normal speech,’ the researchers wrote.

However, among the worst-performing were folded bandanas and knitted masks, which may look fashionable but barely prevented any particles from getting in.

In fact, there was one type of mask that was actually worse than not wearing a face covering at all.

Neck fleeces, also known as gaiters – which are often worn by runners – increased the number of respiratory droplets by turning large droplets into smaller droplets.

Because smaller droplets stay in the air for more time than larger droplets, the mask can trap those particles, and maey neck fleeces are actually be ‘counterproductive.’

‘We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask,’ co-author Dr Martin Fischer,  an associate research professor in the department of chemistry, told CNN.

‘We want to emphasize that we really encourage people to wear masks, but we want them to wear masks that actually work.’ 

The team says people should continue wearing a mask, but added that its proof-of-concept study will help Americans make an informed decision about what offers the best protection. 

‘If everyone wore a mask, we could stop up to 99 percent of these droplets before they reach someone else,’ said co-author Dr Eric Westman, an associate professor of medicine at Duke University, in a statement. 

‘In the absence of a vaccine or antiviral medicine, it’s the one proven way to protect others as well as yourself.’

Trump says Democrats don’t want a vaccine before the election because it will give him credit

trump says democrats dont want a vaccine before the election because it will give him credit

Donald Trump has accused Democrats of not wanting a vaccine against COVID-19 before the election, fearing that it will boost the president’s chances of winning a second term.

Speaking to Fox News for an interview aired on Sunday night, Trump discussed the fight against coronavirus, fears over mail-in voting, and accused his opponent Joe Biden once again of being barely coherent.

The interview was recorded before Ruth Bader Ginsburg’s death on Friday, and so host Mark Levin did not ask the president about the Supreme Court decision. 

He opened his hour-long discussion with questions about coronavirus, as the United State edged towards the grim milestone of 200,000 dead.

Trump said he was confident the virus was going away, and was asked about Democrat attitudes towards a possible vaccine. 

‘They want to denigrate it, because they started hearing rumors about a vaccine in record time,’ said Trump.

‘The reason they are doing this is because they think I’ll get credit if we get a vaccine before the election.’

Trump said that his government had taken unprecedented steps to work for the speedy development of a vaccine. 

‘If this was a typical administration we wouldn’t have a vaccine for two to three years,’ he said. ‘But I have changed it, safely. We have many companies doing it, in phase three trial.

‘Instead of saying wow, this is great news, they are saying oh, it’s coming out too soon, it won’t be safe. These are big companies – they won’t do that, they’ll have tremendous liability.’

Trump said that seniors will be vaccinated first, prioritizing those with heart and respiratory conditions.

Trump also used his interview to mock, once again, his rival in November, Joe Biden.

He said the Democrat candidate ‘barely knows he’s alive’, and was incapable of responding to events. 

‘He’s losing the left now because he never mentions the words law and order,’ said Trump.

‘What we did in Minneapolis was incredible. National Guard – we sent them in – it was over in half an hour. Every one of these cities that has these problems is run by Democrats.’ 

Trump accused Biden of wanting to turn the United States into Venezuela, and said it would become ‘Venezuela on steroids’ if the Democrats win. 

‘And I used to say we’ll be another Venezuela, but I never really…I don’t know that I believed it fully,’ he said. 

‘That wasn’t too long ago. But I do. 

‘If that kind of stuff gets put in, we will be another Venezuela, except on major steroids, OK?’

The president was asked about his frequently-voiced concerns over mail-in voting.

He warned once again that there will be a ‘tremendous disruption’ on Election Day, because voters were confused by the options for casting their ballots, and because of the risks of fraud.

‘Look, they know it doesn’t work because there have been many races using this over the last 14, 15 months – and I heard there was one yesterday or the day before yesterday, the ballots are so mixed up,’ he said.

Trump said he was concerned of reports of ‘missing’ or fraudulent ballots.

‘Now they have a new thing where they don’t want to verify signatures because that makes it easier, so you don’t have to verify a signature,’ he said. 

The president also accused some Democratic governors of being ‘partisan’ and ‘political hacks’ who are trying to sway the election toward his opponent.   

‘It’s a very tough situation,’ he said.

‘You look at these governors and you look at – I mean, I don’t want to insult anybody, but take a look at some of these governors that are in charge of the ballots – beyond partisan – in many cases political hacks.’

Trump added that he has no issue with traditional absentee balloting, in that it is ‘solicited,’ but that many states like New Jersey and Nevada are mailing ballots out unsolicited.

‘When they just dump millions of ballots all over the country, it’s not going to work. It’s going to be a disaster. And they know it,’ he said. 

‘And we’re talking about many millions of ballots. It’s going to be mayhem. It’s going to be bedlam, and this is what they want.’

The president used the interview to vent against John Bolton, describing him as ‘a very stupid person’ who wanted to take America into a new war.

John McCain, who died two years ago, also was a warmonger, Trump said.  

‘If we listened to John McCain it would be World War Five now,’ he said.

He boasted about having ‘rebuilt our military’, adding that he was confident that Russian president Vladimir Putin had a new-found respect for the U.S.  

‘Nobody has been tougher on Russia than I have,’ he said. ‘I guarantee you Putin says that behind closed doors too.’

new south wales records four new coronavirus cases after taxi driver worked eight days infected

New South Wales has recorded just four new COVID-19 cases on Monday, with 7,765 tests conducted across the state.

Three of the new cases are returned travellers in hotel quarantine while the other is a contact of a previously reported case linked to the cluster at the Concord Hospital in Western Sydney.

The dwindling numbers have enticed South Australian Premier Steven Marshall to push to open his state’s border with NSW.

‘We’re hoping that we can get the border open with NSW this week,’ Mr Marshall told ABC Radio Adelaide.

The South Australian Government’s coronavirus transition committee will meet on Tuesday to discuss NSW residents entering the state without needing to quarantine for two weeks.

Mr Marshall said he was mostly concerned about community transmission rates, after a COVID-positive taxi driver worked for eight days while infectious in Sydney.

A major contact tracing operation is underway after the driver worked for more than a week and visited venues in Sydney and the South Coast.

Mr Marshall said the driver’s case was ‘slightly worrying’.  

‘But [SA’s Chief Public Health Officer] Nicola Spurrier and the transition committee will look at that very closely,’ he said.

If a decision is made to relax border controls, Mr Marshall said it would likely be implemented the same day for the convenience of families.

‘You see families completely dislocated — parents not being able to see their children or grandparents not being able to see grandchildren — so there’s a lot of reasons we want this to happen but we can’t do it until it’s safe to do so, but there’s certainly some very good signs this week at this stage,’ he said. 

Test numbers in NSW dropped by nearly 6,000 from 13,635 in the previous 24-hour testing period, which is not uncommon for a weekend. 

NSW Health would like to see levels above 20,000, particularly in South Western Sydney.

Chief Medical Officer Kerry Chant said NSW was at a critical phase in the response to the pandemic.

‘We are trying to identify any undetected chains of transmission in the community to drive it down towards no community transmission,’ she said.

‘That will put us in the best position ahead of the school holidays where we know people will be out and about travelling across the state.’
