Omicron: What we know about the symptoms – Al Jazeera English

Published

 on


A new coronavirus (or SARS-CoV-2) variant, known as Omicron (or B.1.1.529), was first identified by scientists in South Africa on November 24.

The latest variant of the virus that causes the COVID-19 disease is believed to be more transmissible than the already highly transmissible Delta variant. Omicron has already been detected in 106 countries, the WHO has said.

Scientists are also concerned that the variant’s high number of mutations may help it evade vaccinations.

When Delta became the predominant variant, cold-like upper respiratory symptoms became more common, while the loss of taste and smell became less common than in other variants.

With Omicron, some experts have said the symptoms appear to be milder than Delta, while others say it is too soon to confirm.

What are the most common symptoms of Omicron?

Dr Angelique Coetzee, the South African doctor who first alerted authorities to the presence of the new COVID-19 variant, has said muscle aches, fatigue, a scratchy throat and night sweats are common Omicron symptoms.

Early data released on 16 December by the COVID Symptoms Study, run by the health science company Zoe and King’s College London, said cold-like symptoms were the most commonly reported by people with the new Omicron variant.

The data showed that the top five symptoms reported in the app for Omicron infection were a runny nose, headache, fatigue (either mild or severe), sneezing, and a sore throat.

The World Health Organization’s top official in Europe Hans Kluge said 89 percent of those with confirmed Omicron infections in Europe reported symptoms common with other coronavirus variants, including cough, sore throat, fever.

Are Omicron symptoms milder than with other variants?

Coetzee has described the symptoms of Omicron as “very, very mild” compared with those of the Delta variant. She also said that, unlike in other variants, patients have not reported loss of smell or taste and there has been no major drop in oxygen levels with the new variant.

A South African study, which has yet to be peer-reviewed, has suggested there are reduced risks of hospitalisation and severe disease in people infected with the Omicron coronavirus variant versus the Delta one, though the authors say some of that is likely due to high population immunity.

But researchers at Imperial College London (ICL) have said, “We find no evidence (for both risk of hospitalisation attendance and symptom status) of Omicron having different severity from Delta,” although it added that data on hospitalisations remains very limited. Their study is also not yet peer-reviewed.

Experts have also been concerned that the speed at which Omicron appears to spread will offset any reduction in severity.

What impact do vaccines have on symptoms?

Experts have said symptoms of Omicron infection in vaccinated people might be even milder than in those who are unvaccinated, which could lead to the cases to be missed.

Christina Marriott, chief executive of the Royal Society for Public Health (RSPH) said, “Growing evidence shows that people who’ve received two doses of the vaccine typically present with less severe symptoms, such as headache, runny nose, sneezing, sore throat, and loss of smell.

“It’s important for people who’ve been fully vaccinated to stay vigilant for cold-like symptoms and get tested if they’re living or working around people who are at greater risk from the disease.”

Some early data suggests that current vaccinations may offer less protection against infection by Omicron.

The United Kingdom’s Health Security Agency (UKHSA) said that early, non-peer-reviewed data from a study (PDF) suggested that an initial two-dose vaccination course provided less protection against mild disease from Omicron compared with the Delta strain.

But it found boosters restored the protection to an extent – giving an estimated 70 percent to 75 percent protection against mild disease from the new Omicron variant.

How long is Omicron’s incubation period?

The time it takes for an infected person to develop symptoms may be shorter for Omicron than for previous variants, from a full week down to as little as three days or fewer.

“That’s why the spread is occurring at a much faster pace,” said Dr Anita Gupta, an anaesthetist and critical care physician at the Johns Hopkins School of Medicine.

She added that it is possible the incubation period could be shorter or longer depending on a number of variables, including age, underlying health problems and vaccination status.

How do you protect yourself and others?

The WHO has advised the following steps to protect yourself and prevent the spread of COVID-19:

  • Get vaccinated
  • Wear a mask
  • Maintain physical distancing
  • Ventilate indoor spaces
  • Keep good hygiene
  • Self-isolate if you develop symptoms

Adblock test (Why?)

Canadian provincial leader wants to pause truckers’ COVID vaccine mandate

Published

 on

The premier of Canada’s Alberta province on Thursday called on the federal government to pause a COVID-19 vaccine mandate for cross-border truckers that companies say will disrupt the supply chain and fuel inflation.

The mandate, imposed by Ottawa to help curb the spread of the coronavirus, has cost Canadian trucking companies about 10% of their international drivers, six top executives said this week. They said they are hiking wages to lure new operators during the worst labor shortage they have experienced.

Alberta Premier Jason Kenney, at a news conference in Calgary, urged the government to extend an exemption that had been in place for truckers since the start of the pandemic.

Kenney made his request on the same day the United States confirmed its own vaccine border mandate for truckers would start on Saturday. Canada’s has been in place since Jan. 15.

“Common sense tells us that we are at the peak of supply chain constraints across North America, around the world, huge inflation,” Kenney said.

This is not the moment “to lose potentially thousands of truckers on our roads, bringing groceries up from the US and who knows maybe (COVID) rapid test kits as well,” he said.

As many as 32,000, or 20%, of the 160,000 Canadian and American cross-border truck drivers may be taken off the roads by the mandate, the Canadian Trucking Alliance (CTA) estimates. The industry was short some 18,000 drivers even before the mandate, CTA said.

Prime Minister Justin Trudeau has resisted industry pressure to delay the mandate since it was first announced in November. On Wednesday Trudeau defended the mandate, saying Canada was “aligned” with the United States, its largest trading partner.

On Thursday, Canada’s transport ministry said the measure was not negatively affecting the supply of goods, and cross-border truck traffic had not varied significantly.

Within the next two weeks, consumers will see “there’s not as many choices on the shelves,” said Dan Einwechter, chairman and chief executive officer of Challenger Motor Freight Inc in Cambridge, Ontario.

“Eventually the prices will be passed on from the sellers of those products, because we’re passing on our increases to them,” he said.

Canada’s inflation rate hit a 30-year high of 4.8% in December and economists said the vaccine mandate may contribute to keeping prices higher for longer. In the United States, inflation surged 7% on a year-on-year basis in December, the largest rise in nearly four decades.

More than two-thirds of the C$650 billion ($521 billion) in goods traded annually between Canada and the United States travels on roads.

Rob Penner, president and CEO of Winnipeg, Manitoba-based Bison Transport, said from Jan. 1 it raised the base rate for cross-border drivers by almost 20% but failed to gain any.

“There’s more freight than there is people right now.”

Fresh foods are particularly sensitive to freight problems because they expire rapidly, though all imports from the United States could be affected, trucking managers said.

Canadian firms see labor shortages intensifying and wage pressures increasing, according to a Bank of Canada survey released on Monday. Investors increasingly expect the central bank to raise interest rates next week for the first time since 2018.

Ontario to start lifting COVID-related curbs, Quebec more cautious

Published

 on

Canada’s most populous province of Ontario has blunted transmission of the Omicron coronavirus variant and will gradually ease restrictions on businesses from end-January, Premier Doug Ford said on Thursday.

The health care system is starting to stabilize in the wake of limitations imposed on Jan. 5, Ford told a news conference, saying Omicron cases should peak later this month.

“We can be confident that the worst is behind us and that we are now in a position to cautiously and gradually ease public health measures,” Ford said.

The province will allow restaurants, malls, and cinemas to operate with a 50% capacity limit from Jan. 31, before removing more curbs in February and March.

“While February will continue to present its own challenges, given current trends these are challenges we are confident we can manage,” Ford said.

In neighbouring Quebec, premier Francois Legault said he would maintain restrictions to help protect the health care system even though Omicron cases had peaked.

“I understand we are all tired, but lives are at stake. I’m currently under a lot of pressure to remove measures, but my duty is to be responsible to protect the lives of Quebecers,” he told a news conference.

Ontario and Quebec together account for around 61% of Canada’s population of 38.2 million people.

Canadian vaccine mandate to lead to inflation, empty shelves, trucking executives say

Published

 on

Canadian consumers should soon see higher prices and some empty shelves in supermarkets and other retail outlets because of disruptions stemming from a COVID-19 vaccine mandate for cross-border truckers, top trucking executives warned this week.

The mandate, imposed by Ottawa to help curb the spread of the virus, has cost six Canadian trucking companies about 10% of their international drivers, and many are hiking wages to lure new operators during what they said is the worst labor shortage they have experienced.

Within the next two weeks, consumers will see “there’s not as many choices on the shelves,” said Dan Einwechter, chairman and chief executive officer of Challenger Motor Freight Inc in Cambridge, Ontario.

“Eventually the prices will be passed on from the sellers of those products, because we’re passing on our increases to them,” he said.

Canada’s inflation rate https://www.reuters.com/business/canadas-annual-inflation-rate-hits-48-dec-highest-since-sept-1991-2022-01-19 hit a 30-year high of 4.8% in December and economists said the vaccine mandate may contribute to keeping prices higher for longer. In the United States, inflation surged https://www.reuters.com/world/us/us-consumer-prices-increase-strongly-december-2022-01-12 7% on a year-on-year basis in December, the largest rise in nearly four decades.

Prime Minister Justin Trudeau, who has championed vaccine requirements for federal employees, has resisted pressure from industry to delay or drop the mandate that was announced in November.

The vaccine requirement to enter Canada started on Jan. 15, and the one to enter the United States begins on Saturday.

Since more than two-thirds of the C$650 billion ($521 billion) in goods traded annually between Canada and the United States travels on roads, truckers were deemed essential workers until now and traveled freely even when the border was closed for 20 months.

Trudeau defended the mandate on Wednesday, saying Canada was “aligned” with the United States, its largest trading partner.

“We will continue to make sure that we are getting what we need in Canada while, as always, putting the safety and health of Canadians as our top priority,” Trudeau said.

As many as 32,000, or 20%, of the 160,000 Canadian and American cross-border truck drivers may be taken off the roads by the mandate, the Canadian Trucking Alliance (CTA) estimates. The industry was short some 18,000 drivers even before the mandate, CTA said.

“We raised our base rate for cross-border drivers effective Jan. 1 by almost 20% … and it didn’t gain us any drivers,” said Rob Penner, president and CEO of Winnipeg, Manitoba-based Bison Transport. “There’s more freight than there is people right now.”

Canada’s transport ministry said in a statement the measure was not negatively affecting the supply of goods, while cross-border truck traffic had not varied significantly since the mandate came into effect.

BAD TIMING

The six executives who manage nearly 9,200 trucks between their companies and have a combined 173 years in the industry say strong demand for freight during a labor shortage will inevitably translate into higher prices for consumers.

“We’ve been oversold by 5% or 10%, depending on the day, for the last four or five months … The timing of all this couldn’t have been worse,” said Mark Seymour, CEO of Kriska Transportation Group in Prescott, Ontario.

Canadian firms see labor shortages intensifying and wage pressures increasing, according to a Bank of Canada survey https://www.reuters.com/world/americas/firms-see-increasing-labor-shortages-wage-pressures-bank-canada-survey-2022-01-17 released on Monday.

Fresh foods are particularly sensitive to freight problems because they expire rapidly, though all imports from the United States could be affected, the trucking managers said.

“We have to move the milk, we have to move food. But the rates are going to be much higher,” said Doug Sutherland, president of Sutherland Group Enterprises in Salmo, British Columbia.

“Inflation is going to be the biggest impact of what’s going on here.”
