US winter storm will bring frostbite within minutes

Published

 on

Plunging temperatures wreaking havoc across the US and Canada can lead to frostbite on bare skin in only five to 10 minutes, experts are warning.

A powerful Arctic winter storm has placed more than 135 million people under weekend weather alerts ahead of the busiest travel days of the year.

The alerts stretch from coast to coast and reach as far south as the US-Mexico border and Florida, the Sunshine State.

Major airports have cancelled thousands of flights as the storm intensifies.

The cold snap could bring the iciest Christmas in decades, say forecasters.

The National Weather Service (NWS) said temperatures of -50F (-45C) and -70F were possible by the end of this week in some parts of the country.

They warned that even in major metro areas, like the city of Des Moines, Iowa, frostbite will be a major danger.

Frostbite is caused when blood flow is reduced, often to extremities like the nose and cheeks or fingers and toes. The lack of warm blood can lead to tissue freezing and rupturing, and in some cases, amputation.

Meteorologists say the winter storm could become a “bomb cyclone” by Friday.

Bomb cyclone is a term given to an explosive storm that intensifies rapidly, with its central air pressure dropping by at least 24 millibars in 24 hours.

“This is not like a snow day, when you were a kid, this is serious stuff,” President Joe Biden said in a White House briefing on Thursday.

The Arctic air mass is projected to bring strong wind gusts and temperature of 15F (-9.4C) to El Paso, Texas, where newly arrived undocumented migrants are sleeping rough on city streets.

The governor of New York state, Kathy Hochul, declared a state of emergency in anticipation of the storm.

The threat of flooding and ice jams are “going to wreak a lot of havoc in our community”, she said. Ice jams happen when large pieces of ice block the flow of a river and can cause flooding.

The governors of Kentucky, North Carolina, West Virginia, Georgia and Oklahoma have also declared states of emergency, while Wisconsin declared an “energy emergency”.

Ohio governor, Mike DeWine, called the weather a “unique and dangerous situation”, particularly as people travel to be with loved ones over Christmas.

Florida is projected to see its coldest Christmas in 30 years.

The NWS has described it as a “once-in-a-generation” winter weather event, saying on Thursday that “life-threatening wind chills” will strike the east coast on Friday.

Snow and powerful winds are expected to cause damage and power outages in the Midwest and Canada.

The NWS warned more than 100 daily cold temperature records could be tied or broken over the next few days.

  • In Colorado, temperatures dipped to a record-breaking low of -9F from 42F on Thursday
  • The city of Cheyenne, Wyoming, set a record for its greatest one-hour temperature drop, after going from 43F to 3F within 30 minutes. Elsewhere in the western state, temperatures have dropped as low as -35F
  • Nearly a dozen record low temperatures were also set in neighbouring Montana
  • Blizzard conditions have hit both North Dakota and South Dakota
  • In Chicago, a winter storm warning is in effect until Saturday, bringing with it several inches of snow and winds topping 50mph (80km/h)
  • In Canada, much of Ontario and parts of Quebec are also bracing for a major winter storm that is expected to last through the Christmas weekend

More than 5,300 flights in the US have already been cancelled on Thursday and Friday, according to the flight-tracking site FlightAware.

In anticipation of travel disruptions, major airlines including United, Delta and American have offered to waive fees for travellers who wish to reschedule their flights.

Roads along the Colorado-Wyoming border were closed on Wednesday due to nearly zero visibility.

WHO decision on COVID-19 emergency won't effect Canada's response: Tam – CP24

Published

 on


OTTAWA – On Monday, exactly three years from the day he declared COVID-19 to be a global public health emergency, World Health Organization director-general Tedros Adhanom Ghebreyesus will decide whether to call it off.

But declaring an end to the “public health emergency of international concern” would not mean COVID-19 is no longer a threat. It will also not do much to change Canada’s approach.

“In Canada, we’re already doing what we need to do,” chief public health officer Dr. Theresa Tam said in her most recent COVID-19 update.

300x250x1

She said the WHO discussion is important but COVID-19 monitoring and public health responses are not going to end. That includes continued surveillance of cases, particularly severe illness and death, and vaccination campaigns.

The WHO’s emergency committee, which was struck in 2020 when COVID-19 first emerged as a global health threat, voted Friday on whether to maintain the formal designation of a public health emergency.

Tedros will make the final call Monday based on the advice the committee gives him.

He warned earlier this week that he remains concerned about the impact of the virus, noting there were 170,000 deaths from COVID-19 reported around the world in the last two months.

“While I will not pre-empt the advice of the emergency committee, I remain very concerned by the situation in many countries and the rising number of deaths,” he said Jan. 24.

“While we are clearly in better shape than three years ago when this pandemic first hit, the global collective response is once again under strain.”

He is worried not enough health-care workers or seniors are up to date on vaccinations, that access to antivirals is limited and that health systems around the world remain fragile following three years of pandemic strain.

In Canada, there was a noticeable rise in cases, hospitalizations and deaths over Christmas and early in January but all are trending down again. Tam said there were no surges of the virus anywhere in Canada, though the latest variant of Omicron was being watched closely.

Federal surveillance data shows more than 30 people are still dying of COVID-19 every day, and hundreds of people are still hospitalized.

The formal designation of the global public health emergency was made on Jan. 30, 2020, when 99 per cent of confirmed COVID-19 cases were still restricted to China.

The decision was made to declare an emergency because human-to-human transmission was starting to occur outside China, and the hope was that by designating an emergency it could prompt a public health response that could still limit the impact of COVID-19.

That did not happen. On March 11, 2020, Tedros declared a global pandemic, practically begging countries to do more to slow it down.

The declaration of a pandemic meant that there was exponential growth in the spread of the virus.

By WHO terminology, a “public health emergency of international concern” is the highest formal declaration and the one which triggers a legally binding response among WHO member countries, including Canada.

It is what is done when a health threat is “serious, sudden, unusual or unexpected,” when it carries global public health implications and may require “immediately international action.”

A designation prompts the WHO director-general to issue recommendations for member countries including increased surveillance to identify new cases, isolating or quarantining infected people and their close contacts, travel measures such as border testing or closures, public health communications, investments in research and collaboration on treatments and vaccinations.

Dr. Sameer Elsayed, an infectious diseases physician and the director adult infectious diseases residency training at Western University in London, Ont., said to his mind the WHO should end the global emergency designation even though the pandemic itself is not over.

“I don’t know that we should continue to call it an emergency,” he said. “I hope they say that we’re going to bring it down a notch.”

Elsayed said for vulnerable populations, including the elderly and those with compromised immune systems, COVID-19 continues to pose a serious threat, but for most people there are far bigger threats, including suicide. He said with limited health resources, COVID-19 needs to be put in its proper place alongside other health issues.

Children, in particular, said Elsayed, are much more at risk from influenza and RSV than COVID-19 in wealthy countries, and from food insecurity and the lack of access to clean water in many developing nations.

Tam said regardless of what WHO decides, Canada won’t stop monitoring the evolution of the virus that causes COVID-19, including for new variants that may require adjustments to vaccines or other treatments.

She also said we must continue to monitor the ongoing developments in long COVID.

“We mustn’t, I think, let go of the gains that we’ve had in the last several years,” she said.

“I think whatever the decision is made by the director-general of WHO, I think we just need to keep going with what we’re doing now.”

This report by The Canadian Press was first published Jan. 27, 2023.

COVID still a concern despite drop in flu, RSV cases: expert – CTV News

Published

 on


As RSV and flu cases steadily decline in Canada, the World Health Organization (WHO) is set to announce on Monday whether it still considers COVID-19 a global health emergency.

Ahead of that announcement, one of Canada’s top infectious disease specialists warns that the WHO’s consensus won’t necessarily mean the virus is behind us.

“I think it’s important to point out that this is not about … whether COVID is gone or not,” said Dr. Lisa Barrett, an assistant professor in the Department of Microbiology and Immunology as well as the Department of Medicine in the Faculty of Medicine at Dalhousie University.

“This is a real committee-based decision at the WHO level to decide in whether this is still a public health emergency of international concern,” she told CTV News Channel Sunday.

Barrett explained that this a matter of prioritizing access to resources and research, and not to determine an end point for COVID-19.

“So what this all means is that COVID is not done,” she said. “And the way it looks in different countries is different in many situations. That’s what they’re trying to decide at this point, not whether a pandemic is done or whether COVID is going away.”

WHO director-general Tedros Adhanom Ghebreyesus will make the official call on the status of COVID-19, based on the advice of his committee. Earlier this week, he warned that he remains concerned about the impact of the virus and mentioned that there were 170,000 COVID-related deaths reported around the world in the last two months.

The WHO update comes at a time when concerns over a combination of respiratory illnesses are easing. Canadian data shows that influenza hospitalizations are now dropping.

“We’re starting to see influenza, perhaps RSV, starting to come down somewhat,” Barrett said.

“There’s still a lot of debate about whether we’re catching many cases that are not important. But really, I think the big [question] from the last year as we start to see influenza and RSV maybe go down is, what’s the best way forward?”

Barrett noted that the FDA recommended a change to booster shot roll outs.

“They’re suggesting a once-a-year, similar to a flu shot. I think that’s the right approach at this point,” she said.

“I think the first thing we should remind Canadians is that if they are due for an additional dose in the vulnerable populations — older folks, people who have bad immune systems — please don’t think it’s too early to go out and get that last dose from the fall if you haven’t.”

Where did B.C.’s beloved Nanaimo Bar come from?

Published

 on

The Nanaimo bar. It’s a sweet treat made from chocolate, custard, coconut and walnuts. Love it or hate it, it’s uniquely British Columbian.

But where did this chocolatey delicacy come from?

To celebrate the launch of CBC’s new permanent Nanaimo bureauNorth by Northwest host Margaret Gallagher spoke to food historian Lenore Newman about the origins of the treat that shares the city’s name.

Newman says it can be traced back to three women in Nanaimo after the Second World War.

Originally — and uncreatively — called chocolate slices, Newman says the “dainties” popped up around 1952, in, no surprise here, Nanaimo. The base layer, made of graham wafer crumbs, shows up earlier, but the square as we know it with the thick custard middle and chocolate on top appeared in a local hospital auxiliary cookbook in the early ’50s, Newman said.

 

A B.C. baker’s “ultimate” Nanaimo bars

 

CBC’s Midday talks to a woman who extended her recipe into a business selling aprons and tea towels in 1987.

It was first deemed the Nanaimo bar by Vancouver Sun columnist Edith Adams in 1953 when she wrote that the dessert came from Nanaimo.

This is important to note, Newman says, because other places such as Mississauga and England have tried to claim it as their own.

The bar was later featured in the Expo ’86 cookbook, giving it a little more notoriety.

“I think if it had been called the chocolate slice, it would have faded into the past, but the fact that it was called the Nanaimo bar kept it rolling forward,” Newman said.

 

A modern interpretation of Nanaimo Bar loved around the world

The Nanaimo bar’s fame has been far-reaching; when Harry and Megan visited B.C. in 2020, their interest in the treats caused a media frenzy in the U.K. and the U.S., prompting questions of what the square was and where it came from.

The Daily Mail even printed a headline titled: Were Harry and Meghan Markle lured to Canada by chocolate treats?

And in 2021, British Columbians were nonplussed when the New York Times published a recipe and photo of a Nanaimo bar that was, quite frankly, all wrong.

That wasn’t the first time people were offended over Nanaimo bars. In 2019, a Canada Post stamp featuring the dessert showed far too much of the middle layer, prompting outrage from Nanaimo bar enthusiasts.

Famous, infamous

“I like to say it’s like the Kardashian of Canadian desserts in that it’s famous for being famous and sometimes infamous, and it’s amazing how much play it gets,” Newman said.

So, how do you make the perfect Nanaimo bar? Here’s a recipe from The Great Canadian Baking Show.

Ingredients

For the crust:

  • 1 cup graham wafer crumbs.
  • 3/4 cup unsweetened flaked coconut.
  • 1/2 cup finely chopped walnuts.
  • 1/3 cup cocoa.
  • 1/4 cup sugar.
  • 1/4 tsp salt.
  • 1/3 cup unsalted butter, melted.
  • 1 egg, beaten.
  • 1/2 tsp vanilla.

For the middle layer:

  • 1/3 cup unsalted butter, softened.
  • 2 tbsp custard powder.
  • 2 tbsp milk.
  • 1/2 tsp vanilla.
  • 1/8 tsp salt.
  • 2 cups icing sugar.

For the glaze:

  • 110 g semi-sweet chocolate, roughly chopped (about 3/4 cup).
  • 2 tbsp unsalted butter.

Instructions

Heat oven to 350°F. Line an eight-inch pan with parchment paper, with ends extending over the sides of the pan. Set aside.

Stir together graham crumbs, coconut, walnuts, cocoa, sugar and salt. Add butter, egg and vanilla, stirring to combine.  Press firmly into the prepared pan.

Bake until firm, about 10-12 minutes. Set aside to cool.

Meanwhile, prepare the middle layer. Mix butter and custard powder in a large bowl with a hand mixer. Add milk, vanilla and salt and mix to incorporate. Add icing sugar in two additions. Mix until light and fluffy. Spread over the bottom layer. Refrigerate for one hour.

While the crust and middle layer are in the refrigerator, stir chocolate and butter together in a medium heatproof bowl over a pot of simmering water until melted.

Spread chocolate glaze over the middle layer. Chill for 30 minutes. Remove from the pan with parchment edges and cut into 25 squares.

Store in an airtight container in the fridge.
