Masks had no impact, full lockdown had no impact - Study of 30 countries finds

The data of this study is clear, it goes only one way : Masks have no impact.

Wearing masks is just one part of an overall strategy to minimise risk. Nobody is claiming they are THE answer.

 

I asked you to provide a different study that supports your claim. You haven't done so. And yes, I have been reading the thread - every single post, in fact.

 

I could quote medical experts advising mask wearing as a sensible precaution all day long. 

 

Even experts who favor masking the masses say their impact on the spread of disease is likely to be modest. Many are also afraid to promote mask buying amid dire shortages at hospitals. But as the pandemic wears on, some public health experts think government messages discouraging mask wearing should shift.

 

“It’s really a perfectly good public health intervention that’s not used,” argues KK Cheng, a public health expert at the University of Birmingham. “It’s not to protect yourself. It’s to protect people against the droplets coming out of your respiratory tract.”

Cheng and others stress that however masks are used, people must practice social distancing and stay at home as much as possible to prevent the spread of the novel coronavirus. When people do venture out and interact, they’re likely to spew some saliva. “I don’t want to frighten you, but when people speak and breathe and sing—you don’t have to sneeze or cough—these droplets are coming out,” he says.

Science has tried to interview George Gao, director-general of the Chinese Center for Disease Control and Prevention (CDC), for 2 months. Last week he responded

 

Gao oversees 2000 employees—one-fifth the staff size of the U.S. Centers for Disease Control and Prevention—and he remains an active researcher himself. In January, he was part of a team that did the first isolation and sequencing of severe acute respiratory syndrome 2 (SARS-CoV-2), the virus that causes COVID-19. He co-authored two widely read papers published in The New England Journal of Medicine (NEJM) that provided some of the first detailed epidemiology and clinical features of the disease, and has published three more papers on COVID-19 in The Lancet.

 

 

Q: The lockdown in China began on 23 January in Wuhan and was expanded to neighboring cities in Hubei province. Other provinces in China had less restrictive shutdowns. How was all of this coordinated, and how important were the “supervisors” overseeing the efforts in neighborhoods?

 

A: You have to have understanding and consensus. For that you need very strong leadership, at the local and national level. You need a supervisor and coordinator working with the public very closely. Supervisors need to know who the close contacts are, who the suspected cases are. The supervisors in the community must be very alert. They are key.

 

Q: What mistakes are other countries making? 

 

A: 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.

Recent studies suggest that coronavirus disease 2019 (COVID-19) may be transmitted by infected persons even in the absence of symptoms of disease. While social distancing and good hand hygiene are the most important methods to prevent virus transmission, new guidelines state that healthy individuals can consider wearing masks in public settings, particularly when physical distancing is difficult (like in grocery stores or pharmacies). Primary benefits of wearing a mask include limiting the spread of the virus from someone who knows or does not know they have an infection to others. Masks also remind others to continue practicing physical distancing. However, nonmedical masks may not be effective in preventing infection for the person wearing them.

Hey Lothesome or whatever your name is.

You know what will work for you instead of a mask....Duct tape!

Ok, here is a study that finds that 'surgical and cloth masks' are ineffective in preventing SARS-CoV-2 penetrating the material.

 

The study did not look at the effectiveness in reducing the distance droplets can travel, only whether droplets could pass through the mask.

 

"...while it remains unclear just how large particles containing SARS-CoV-2 and carried by the breath are, estimates regarding the size of a similar coronavirus, SARS-CoV, suggest that “Surgical masks are unlikely to effectively filter” it."

...

This study did not aim to verify whether surgical or cloth masks are able to shorten the trajectory of droplets emitted through coughing.

Social distancing is clearly the most important prevention strategy. Masks may have limited effectiveness when in close contact, but with social distancing being practiced, it may prevent droplets travelling the extra 'social distance' being observed. The study does not make a finding in this respect.

The op is making a conclusion, a conclusion the report specifically states should not be made. Thats it in a nutshell.

 

He has not posted his standard reply on this page of the thread yet. Wont be long.

I appreciate that you clearly state that this is your opinion.
Nevertheless I do not agree.
