Experts say Canada's three-layer face mask recommendations make sense – CP24 Toronto's Breaking News

As the cold winter weather forces most of us indoors during the COVID-19 pandemic, Canada’s health leaders say it’s time to upgrade our cloth face masks.

Dr. Theresa Tam, the country’s chief public health officer, said in a news conference Tuesday that masks with three layers – two cloth plus a filter – are now recommended over the two-layer face coverings previously suggested.

While the new recommendations caused a stir in the House of Commons on Wednesday, with Conservative leader Erin O’Toole suggesting they’re not in line with current provincial advice and may breed confusion, medical experts across Canada agreed that a three-layer mask works better than one with two layers.

Dr. Jing Wang, a clinical instructor at the University of British Columbia who has studied different face mask materials, says the timing of the new recommendations makes sense.

“I think it’s prudent to have a more stringent indoor mask policy, because it’s very difficult to stay distant indoors,” she said. “And if we’re spending a lot of time indoors, there’s more aerosol buildup in the air, so we should especially be wearing an effective mask.”

Wang says a two-layer cotton mask is about 60 per cent effective in trapping coronavirus particles being spewed from the wearer’s mouth – provided the mask is being worn correctly and has a tight fit around the cheeks.

But adding a filter to the same two-layer cloth mask can increase its effectiveness.

“You can kick it up to about 80 or 90 (per cent), and a regular surgical mask is anywhere between 60 to 90 per cent effective,” she said. “So essentially, when you have a two-layer cloth mask with a filter, it could be just as good as a single-use surgical mask.”

Dr. Lisa Bryski, an emergency room physician in Winnipeg, wasn’t surprised by Canada’s new mask-wearing measures, saying they align with those of the World Health Organization (WHO).

Bryski also says our knowledge of face mask effectiveness has expanded since the pandemic began, which would explain why recommendations are evolving.

“We’ve come a long way since March, when you think of how we used to approach the virus,” Bryski said. “We have studies showing that wearing a mask is better than no masks, and that … two (layers) is better than one.

“And now we’re finding that two layers with a filter is better than just two.”

Tam said in Tuesday’s news conference that the new guidelines don’t necessarily mean we have to throw out all of our current cloth masks and replace them with new ones.

She recommended adding a filter to existing masks, and Health Canada’s website now includes instructions for making three-layered masks at home.

The website says filters “add an extra layer of protection against COVID-19 by trapping small infectious particles,” and suggests using either a folded paper towel or non-woven propylene materials like craft fabric, which is used to make some reusable shopping bags.

Wang warns that not all non-woven polypropylene products are created equal, however.

“And it’s not all equally effective,” she added. “Some of them are actually hazardous for the body because they contain preservatives.”

She suggests using a dried out baby wipe – one of the fabrics she tested in her research – because it’s biocompatible, breathable and contains little to no preservatives.

Wang doesn’t propose using coffee filters to line our masks, however, saying they can be thicker than other non-woven fabric and interfere with breathing.

Dr. Anna Banerji, an infectious disease expert with the University of Toronto, says most two-layer cotton masks can be easily transformed into a three-layer filtered mask by ripping out the seams and adding a filtered material.

“Just open it up and put in some filter paper,” she said. “You can still use them if you put a filter material in between to sort of trap the virus particles.”

Bryski agrees that old masks don’t need to be thrown out, and they can and should still be worn while in the process of replacing or modifying them.

She wouldn’t advise putting two, two-layer masks on top of each other though.

“Two layers is better than nothing right now, so whatever you have, keep wearing and upgrade as you can,” she said. “But there haven’t been studies showing whether four-layer masks, or wearing double masks, are better than two because most of them are made of the same material.”

Bryski said mask upgrades shouldn’t hamper their breathability, and to refrain from using obstructive material “like plastic wrap or other solids.”

Wang stressed that mask design can be more important than the number of layers on it.

And proper fit on the face will determine how effective a mask actually is.

“Just because you’re wearing a three-layer mask with a filter doesn’t mean it’s automatically more effective if have your nose exposed or if it’s not tightly fitted around your face,” she said. “If you’re not going to wear it tightly and properly, then I don’t see too much of an advantage of having a three-layer mask.”

Virginia Democrats advance efforts to protect abortion, voting rights, marriage equality

Published

 on

 

RICHMOND, Va. (AP) — Democrats who control both chambers of the Virginia legislature are hoping to make good on promises made on the campaign trail, including becoming the first Southern state to expand constitutional protections for abortion access.

The House Privileges and Elections Committee advanced three proposed constitutional amendments Wednesday, including a measure to protect reproductive rights. Its members also discussed measures to repeal a now-defunct state constitutional ban on same-sex marriage and ways to revise Virginia’s process to restore voting rights for people who served time for felony crimes.

“This meeting was an important next step considering the moment in history we find ourselves in,” Democratic Del. Cia Price, the committee chair, said during a news conference. “We have urgent threats to our freedoms that could impact constituents in all of the districts we serve.”

The at-times raucous meeting will pave the way for the House and Senate to take up the resolutions early next year after lawmakers tabled the measures last January. Democrats previously said the move was standard practice, given that amendments are typically introduced in odd-numbered years. But Republican Minority Leader Todd Gilbert said Wednesday the committee should not have delved into the amendments before next year’s legislative session. He said the resolutions, particularly the abortion amendment, need further vetting.

“No one who is still serving remembers it being done in this way ever,” Gilbert said after the meeting. “Certainly not for something this important. This is as big and weighty an issue as it gets.”

The Democrats’ legislative lineup comes after Republican Governor Glenn Youngkin, to the dismay of voting-rights advocates, rolled back a process to restore people’s civil rights after they completed sentences for felonies. Virginia is the only state that permanently bans anyone convicted of a felony from voting unless a governor restores their rights.

“This amendment creates a process that is bounded by transparent rules and criteria that will apply to everybody — it’s not left to the discretion of a single individual,” Del. Elizabeth Bennett-Parker, the patron of the voting rights resolution, which passed along party lines, said at the news conference.

Though Democrats have sparred with the governor over their legislative agenda, constitutional amendments put forth by lawmakers do not require his signature, allowing the Democrat-led House and Senate to bypass Youngkin’s blessing.

Instead, the General Assembly must pass proposed amendments twice in at least two years, with a legislative election sandwiched between each statehouse session. After that, the public can vote by referendum on the issues. The cumbersome process will likely hinge upon the success of all three amendments on Democrats’ ability to preserve their edge in the House and Senate, where they hold razor-thin majorities.

It’s not the first time lawmakers have attempted to champion the three amendments. Republicans in a House subcommittee killed a constitutional amendment to restore voting rights in 2022, a year after the measure passed in a Democrat-led House. The same subcommittee also struck down legislation supporting a constitutional amendment to repeal an amendment from 2006 banning marriage equality.

On Wednesday, a bipartisan group of lawmakers voted 16-5 in favor of legislation protecting same-sex marriage, with four Republicans supporting the resolution.

“To say the least, voters enacted this (amendment) in 2006, and we have had 100,000 voters a year become of voting age since then,” said Del. Mark Sickles, who sponsored the amendment as one of the first openly gay men serving in the General Assembly. “Many people have changed their opinions of this as the years have passed.”

A constitutional amendment protecting abortion previously passed the Senate in 2023 but died in a Republican-led House. On Wednesday, the amendment passed on party lines.

If successful, the resolution proposed by House Majority Leader Charniele Herring would be part of a growing trend of reproductive rights-related ballot questions given to voters. Since 2022, 18 questions have gone before voters across the U.S., and they have sided with abortion rights advocates 14 times.

The voters have approved constitutional amendments ensuring the right to abortion until fetal viability in nine states: Arizona, California, Colorado, Maryland, Michigan, Missouri, Montana, Ohio and Vermont. Voters also passed a right-to-abortion measure in Nevada in 2024, but it must be passed again in 2026 to be added to the state constitution.

As lawmakers debated the measure, roughly 18 members spoke. Mercedes Perkins, at 38 weeks pregnant, described the importance of women making decisions about their own bodies. Rhea Simon, another Virginia resident, anecdotally described how reproductive health care shaped her life.

Then all at once, more than 50 people lined up to speak against the abortion amendment.

“Let’s do the compassionate thing and care for mothers and all unborn children,” resident Sheila Furey said.

The audience gave a collective “Amen,” followed by a round of applause.

Vancouver Canucks winger Joshua set for season debut after cancer treatment

Published

 on

 

Vancouver Canucks winger Dakota Joshua is set to make his season debut Thursday after missing time for cancer treatment.

Head coach Rick Tocchet says Joshua will slot into the lineup Thursday when Vancouver (8-3-3) hosts the New York Islanders.

The 28-year-old from Dearborn, Mich., was diagnosed with testicular cancer this summer and underwent surgery in early September.

He spoke earlier this month about his recovery, saying it had been “very hard to go through” and that he was thankful for support from his friends, family, teammates and fans.

“That was a scary time but I am very thankful and just happy to be in this position still and be able to go out there and play,,” Joshua said following Thursday’s morning skate.

The cancer diagnosis followed a career season where Joshua contributed 18 goals and 14 assists across 63 regular-season games, then added four goals and four assists in the playoffs.

Now, he’s ready to focus on contributing again.

“I expect to be good, I don’t expect a grace period. I’ve been putting the work in so I expect to come out there and make an impact as soon as possible,” he said.

“I don’t know if it’s going to be perfect right from the get-go, but it’s about putting your best foot forward and working your way to a point of perfection.”

The six-foot-three, 206-pound Joshua signed a four-year, US$13-million contract extension at the end of June.

Trump chooses anti-vaccine activist Robert F. Kennedy Jr. as health secretary

Published

 on

 

NEW YORK (AP) — President-elect Donald Trump says he will nominate anti-vaccine activist Robert F. Kennedy Jr. to lead the Department of Health and Human Services, putting him in charge of a massive agency that oversees everything from drug, vaccine and food safety to medical research and the social safety net programs Medicare and Medicaid.

“For too long, Americans have been crushed by the industrial food complex and drug companies who have engaged in deception, misinformation, and disinformation when it comes to Public Health,” Trump said in a post on his Truth Social site announcing the appointment. Kennedy, he said, would “Make America Great and Healthy Again!”

Kennedy, a former Democrat who ran as an independent in this year’s presidential race, abandoned his bid after striking a deal to give Trump his endorsement with a promise to have a role in health policy in the administration.

He and Trump have since become good friends, with Kennedy frequently receiving loud applause at Trump’s rallies.

The expected appointment was first reported by Politico Thursday.

A longtime vaccine skeptic, Kennedy is an attorney who has built a loyal following over several decades of people who admire his lawsuits against major pesticide and pharmaceutical companies. He has pushed for tighter regulations around the ingredients in foods.

With the Trump campaign, he worked to shore up support among young mothers in particular, with his message of making food healthier in the U.S., promising to model regulations imposed in Europe. In a nod to Trump’s original campaign slogan, he named the effort “Make America Healthy Again.”

It remains unclear how that will square with Trump’s history of deregulation of big industries, including food. Trump pushed for fewer inspections of the meat industry, for example.

Kennedy’s stance on vaccines has also made him a controversial figure among Democrats and some Republicans, raising question about his ability to get confirmed, even in a GOP-controlled Senate. Kennedy has espoused misinformation around the safety of vaccines, including pushing a totally discredited theory that childhood vaccines cause autism.

He also has said he would recommend removing fluoride from drinking water. The addition of the material has been cited as leading to improved dental health.

HHS has more than 80,000 employees across the country. It houses the Food and Drug Administration, the Centers for Disease Control and Prevention, the Medicare and Medicaid programs and the National Institutes of Health.

Kennedy’s anti-vaccine nonprofit group, Children’s Health Defense, currently has a lawsuit pending against a number of news organizations, among them The Associated Press, accusing them of violating antitrust laws by taking action to identify misinformation, including about COVID-19 and COVID-19 vaccines. Kennedy took leave from the group when he announced his run for president but is listed as one of its attorneys in the lawsuit.
