“I want to apologize for advocating for the use of masks” – Spread of respiratory illnesses not slowed down by mask use

Published

7 minute read

The Cochrane Database of Systematic Reviews has released a comprehensive study of Physical interventions to interrupt or reduce the spread of respiratory viruses.  

The study examines the effectiveness of masks and of following a hand hygiene program in reducing the likelihood of acquiring respiratory virus infections such as COVID-19.

British Health Researcher Dr. John Campbell shares the disappointing results in this presentation:

What did we do?
We searched for randomised controlled studies that looked at physical measures to stop people acquiring a respiratory virus infection.

We were interested in how many people in the studies caught a respiratory virus infection, and whether the physical measures had any unwanted effects.

What did we find?
We identified 78 relevant studies. They took place in low‐, middle‐, and high‐income countries worldwide: in hospitals, schools, homes, offices, childcare centres, and communities during non‐epidemic influenza periods, the global H1N1 influenza pandemic in 2009, epidemic influenza seasons up to 2016, and during the COVID‐19 pandemic. We identified five ongoing, unpublished studies; two of them evaluate masks in COVID‐19. Five trials were funded by government and pharmaceutical companies, and nine trials were funded by pharmaceutical companies.

We assessed the effects of:

· medical or surgical masks;

· N95/P2 respirators (close‐fitting masks that filter the air breathed in, more commonly used by healthcare workers than the general public); and

· hand hygiene (hand‐washing and using hand sanitiser).

We obtained the following results:

Medical or surgical masks

Ten studies took place in the community, and two studies in healthcare workers. Compared with wearing no mask in the community studies only, wearing a mask may make little to no difference in how many people caught a flu‐like illness/COVID‐like illness (9 studies; 276,917 people); and probably makes little or no difference in how many people have flu/COVID confirmed by a laboratory test (6 studies; 13,919 people). Unwanted effects were rarely reported; discomfort was mentioned.

N95/P2 respirators

Four studies were in healthcare workers, and one small study was in the community. Compared with wearing medical or surgical masks, wearing N95/P2 respirators probably makes little to no difference in how many people have confirmed flu (5 studies; 8407 people); and may make little to no difference in how many people catch a flu‐like illness (5 studies; 8407 people), or respiratory illness (3 studies; 7799 people). Unwanted effects were not well‐reported; discomfort was mentioned.

Hand hygiene

Following a hand hygiene programme may reduce the number of people who catch a respiratory or flu‐like illness, or have confirmed flu, compared with people not following such a programme (19 studies; 71,210 people), although this effect was not confirmed as statistically significant reduction when ILI and laboratory‐confirmed ILI were analysed separately. Few studies measured unwanted effects; skin irritation in people using hand sanitiser was mentioned.

 


Dr. John Campbells presentation notes with links:

RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks.

There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers, when used in routine care to reduce respiratory viral infection.

Do physical measures such as hand-washing or wearing masks stop or slow down the spread of respiratory viruses?

Medical/surgical masks compared to no masks

Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness

wearing a mask may make little to no difference in how many people caught a flu-like illness/COVID-like illness

Risk ratio (RR) 0.95, (0.84 to 1.09) 9 trials, n = 276,917 participants

Moderate-certainty evidence.

Wearing masks in the community probably makes little or no difference to the outcome of laboratory-confirmed influenza/SARS-CoV-2 RR 1.01, (CI 0.72 to 1.42)

6 trials, n = 13,919 Moderate-certainty evidence

Harms were rarely measured and poorly reported (very low-certainty evidence).

N95/P2 respirators compared to medical/surgical masks

We pooled trials comparing N95/P2 respirators with medical/surgical masks

We are very uncertain on the effects of N95/P2 respirators compared with medical/surgical masks on the outcome of clinical respiratory illness

Compared with wearing medical or surgical masks, wearing N95/P2 respirators probably makes little to no difference in how many people have confirmed flu and may make little to no difference in how many people catch a flu-like illness, or respiratory illness.

Confirmed influenza RR 0.70, (0.45 to 1.10) N = 7,779 Very low-certainty evidence

Influenza like illness N95/P2 respirators compared with medical/surgical masks may be effective for ILI RR 0.82 N= 8,407 Low-certainty evidence

The use of a N95/P2 respirators compared to medical/surgical masks

Probably makes little or no difference for laboratory-confirmed influenza infection RR 1.10 N = 8,407 Moderate-certainty evidence

Restricting pooling to healthcare workers made no difference to the overall findings.

Harms were poorly measured and reported

Discomfort wearing medical/surgical masks or N95/P2 respirators was mentioned in several studies

Coutts Three verdict: A warning to protestors who act as liaison with police

Published on

From the Frontier Centre for Public Policy

By Ray McGinnis

During the trial numbers of RCMP officers conceded that the Coutts Three were helpful in their interactions with the law. As well, there didn’t seem to be any truth to the suggestion that Van Huigenbos, Van Herk and Janzen were leaders of the protest.

Twelve jurors have found the Coutts Three guilty of mischief over $5,000 at a courthouse in Lethbridge, Alberta. Marco Van Huigenbois, Alex Van Herk and George Janzen will appear again in court on July 22 for sentencing.

Van Huigenbois, Van Herk and Janzen were each protesting at the Coutts Blockade in 2022. A blockade of Alberta Highway 4 began on January 29, 2022, blocking traffic, on and off, on Alberta Highway 4 near the Coutts-Sweetgrass Canada-USA border crossing. The protests were in support of the Freedom Convoy protests in Ottawa.

Protests began due to the vaccine mandates for truckers entering Canada, and lockdowns that bankrupted 120,000 small businesses. Government edicts were purportedly for “public health” to stop the spread of the C-19 virus. Yet the CDC’s Dr. Rachel Wallensky admitted on CNN in August 2021 the vaccine did not prevent infection or stop transmission.

By February 2022, a US court forced Pfizer to release its “Cumulative Analysis of Post-Authorization Adverse Event Reports” revealing the company knew by the end of February, 2021, that 1,223 people  had a “case outcome” of “fatal” as a result of taking the companies’ vaccine.

On the day of February 14, 2022, the three men spoke to Coutts protesters after a cache of weapons had been displayed by the RCMP. These were in connection with the arrest of the Coutts Four. Van Huigenbos and others persuaded the protesters to leave Coutts, which they did by February 15, 2022.

During the trial numbers of RCMP officers conceded that the Coutts Three were helpful in their interactions with the law. As well, there didn’t seem to be any truth to the suggestion that Van Huigenbos, Van Herk and Janzen were leaders of the protest.

RCMP officer Greg Tulloch testified that there were a number of “factions” within the larger protest group. These factions had strong disagreements about how to proceed with the protest. The Crown contended the Coutts Three were the leaders of the protest.

During his testimony, Tulloch recalled how Van Huigenbos and Janzen assisted him in getting past the “vehicle blockade to enter Coutts at a time during the protest when access to Coutts from the north via the AB-4 highway was blocked.” Tulloch also testified that Janzen and Van Huigenbos helped with handling RCMP negotiations with the protesters. Tulloch gave credit to these two “being able to help move vehicles at times to open lanes on the AB-4 highway to facilitate the flow of traffic in both directions.”

During cross examination by George Janzen’s lawyer, Alan Honner, Tulloch stated that he noticed two of the defendants assisting RCMP with reopening the highway in both directions. Honner said in summary, “[Marco Van Huigenbos and George Janzen] didn’t close the road, they opened it.”

Mark Wielgosz, an RCMP officer for over twenty years, worked as a liaison between law enforcement and protesters at the Coutts blockade. Taking the stand, he concurred that there was sharp disagreement among the Coutts protesters and the path forward with their demonstration. Rebel News video clips “submitted by both the Crown and defence teams captured these disagreements as demonstrators congregated in the Smuggler’s Saloon, a location where many of the protesters met to discuss and debate their demonstration.” Wielgosz made several attempts to name the leaders of the protest in his role as a RCMP liaison with the protesters, but was unsuccessful.”

However, the Crown maintained that the protest unlawfully obstructed people’s access to property on Highway 4.

Canada’s Criminal Code defines mischief as follows in Section 430:

Every one commits mischief who willfully

(a)  destroys or damages property;

(b)  renders property dangerous, useless, inoperative or ineffective;

(c)   obstructs, interrupts or interferes with the lawful use, enjoyment or operation of property; or

(d)  obstructs, interrupts or interferes with any person in the lawful use, enjoyment or operation of property.

Robert Kraychik reported that “RCMP Superintendent Gordon Corbett…cried (no comment on the sincerity of this emoting) while testifying about a female RCMP officer that was startled by the movement of a tractor with a large blade during the Coutts blockade/protest.” This was the climax of the trial. A tractor moving some distance away from an officer in rural Alberta, with blades. The shock of it all.

No evidence was presented in the trial that Van Huigenbos, Van Herk and Janzen destroyed or damaged property. Officers testified they couldn’t identify who the protest leaders were. They testified the defendants assisted with opening traffic lanes, and winding down the protest.

By volunteering to liaise with the RCMP, the Crown depicted the Coutts Three as the protest leaders. Who will choose to volunteer at any future peaceful, non-violent, protest to act as a liaison with the policing authorities? Knowing of the verdict handed down on April 16, 2024, in Lethbridge?
