Canada’s public health agency warns threat of COVID-19 resurgence in Canada ‘not just hypothetical’

Published

 on

While the COVID-19 epidemic in Canada remains “largely under control,” one of Canada’s top public health officials is warning that the potential for a significant spike in new cases “is not just hypothetical, as this is exactly what we are already seeing in some other parts of the world.”

As the United States nears three million cases of COVID-19 and states like Texas and California show record-high numbers of newly-reported cases, Canada’s public health agency on Wednesday released the latest figures in its modelling of the coronavirus outbreak in this country, showing the epidemic is on the same trajectory as it was at the end of June.

Dr. Howard Njoo, deputy chief public health officer of Canada, told a media briefing in Ottawa today that “the current patterns of COVID-19 infections show limited to no transmission in most areas of the country.”

Dr. Njoo pointed out that most of the recent outbreaks have been localized, citing northern Saskatchewan and Ontario’s Peel and Windsor-Essex regions as hotspots that emerged over the last two weeks.

These outbreaks have led to Canada’s Rt number — representing the average number of people infected by each individual case — rising above 1 after staying below 1 for most of the last 10 weeks. An Rt above 1 suggests the spread of the disease is growing.

Dr. Njoo said that “with cases low in number, the daily Rt is likely to fluctuate dramatically. It remains important for us to closely monitor for new cases and outbreaks that could arise in any part of the country, even in places which might have few or no cases at the moment.”

The Public Health Agency of Canada says transmission of the coronavirus is waning in most parts of the country, but warned that Canadians must keep following public health measures to prevent a rebound. 49:52

‘Things can change quickly’

In a press conference in Ottawa earlier today, Prime Minister Justin Trudeau echoed the same warning.

“The situation is stabilizing in Canada today because Canadians did their part and followed public health instructions,” he said, “but we still have to be very careful. Things can change quickly.”

The models forecast that by July 17, Canada will have detected between 106,000 and 111,000 cases and suffered between 8,560 and 8,900 deaths.

 

 

As of July 7, the country had experienced 107,000 cases and 8,818 deaths, according to a tally by CBC News.

The data indicate that cases among Canadians over the age of 80 have declined the most, but that the prevalence of COVID-19 among Canadians between the ages of 20 and 39 has not declined at the same pace.

“To continue to prevent a resurgence and manage the epidemic,” Dr. Njoo said in French, “we need the rate of infection among this age group to decrease in a constant manner. Though severe illness is less frequent among younger age groups, young adults are not protected from serious consequences.”

Young people can also spread the virus to more vulnerable populations.

As of the public health agency’s data up to July 7, there have been only 24 recorded deaths among Canadians under the age of 39 due to COVID-19, representing just 0.3 per cent of the total. But they represent over eight per cent of hospitalized cases and nearly 10 per cent of those admitted to intensive care units.

Dr. Njoo said that, as businesses re-open and personal restrictions are lifted, he expects to see a resurgence in cases. He said there’s a risk of a significant spike in the summer and into the fall without enhanced public health measures related to case detection, contact tracing and quarantining.

The models suggest that without these measures in place, there is a “distinct possibility” that the caseload could explode beyond even the peak of the first wave in April, he said.

And while he thinks things are going well so far, Dr. Njoo said “we need to keep underlining the key public health messages and telling people that no, it’s not over, and if there’s too much of what we call a relapse … then certainly we’ll see more of these outbreaks.”

Teen smoking and other tobacco use drop to lowest level in 25 years, CDC reports

Published

 on

NEW YORK (AP) — Teen smoking hit an all-time low in the U.S. this year, part of a big drop in the youth use of tobacco overall, the government reported Thursday.

There was a 20% drop in the estimated number of middle and high school students who recently used at least one tobacco product, including cigarettes, electronic cigarettes, nicotine pouches and hookahs. The number went from 2.8 million last year to 2.25 million this year — the lowest since the Centers for Disease Control and Prevention’s key survey began in 1999.

“Reaching a 25-year low for youth tobacco product use is an extraordinary milestone for public health,” said Deirdre Lawrence Kittner, director of CDC’s Office on Smoking and Health, in a statement. However, “our mission is far from complete.”

A previously reported drop in vaping largely explains the overall decline in tobacco use from 10% to about 8% of students, health officials said.

The youth e-cigarette rate fell to under 6% this year, down from 7.7% last year — the lowest at any point in the last decade. E-cigarettes are the most commonly used tobacco products among teens, followed by nicotine pouches.

Use of other products has been dropping, too.

Twenty-five years ago, nearly 30% of high school students smoked. This year, it was just 1.7%, down from the 1.9%. That one-year decline is so small it is not considered statistically significant, but marks the lowest since the survey began 25 years ago. The middle school rate also is at its lowest mark.

Recent use of hookahs also dropped, from 1.1% to 0.7%.

The results come from an annual CDC survey, which included nearly 30,000 middle and high school students at 283 schools. The response rate this year was about 33%.

Officials attribute the declines to a number of measures, ranging from price increases and public health education campaigns to age restrictions and more aggressive enforcement against retailers and manufacturers selling products to kids.

Among high school students, use of any tobacco product dropped to 10%, from nearly 13% and e-cigarette use dipped under 8%, from 10%. But there was no change reported for middle school students, who less commonly vape or smoke or use other products,

Current use of tobacco fell among girls and Hispanic students, but rose among American Indian or Alaska Native students. And current use of nicotine pouches increased among white kids.

Whooping cough is at a decade-high level in US

Published

 on

MILWAUKEE (AP) — Whooping cough is at its highest level in a decade for this time of year, U.S. health officials reported Thursday.

There have been 18,506 cases of whooping cough reported so far, the Centers for Disease Control and Prevention said. That’s the most at this point in the year since 2014, when cases topped 21,800.

The increase is not unexpected — whooping cough peaks every three to five years, health experts said. And the numbers indicate a return to levels before the coronavirus pandemic, when whooping cough and other contagious illnesses plummeted.

Still, the tally has some state health officials concerned, including those in Wisconsin, where there have been about 1,000 cases so far this year, compared to a total of 51 last year.

Nationwide, CDC has reported that kindergarten vaccination rates dipped last year and vaccine exemptions are at an all-time high. Thursday, it released state figures, showing that about 86% of kindergartners in Wisconsin got the whooping cough vaccine, compared to more than 92% nationally.

Whooping cough, also called pertussis, usually starts out like a cold, with a runny nose and other common symptoms, before turning into a prolonged cough. It is treated with antibiotics. Whooping cough used to be very common until a vaccine was introduced in the 1950s, which is now part of routine childhood vaccinations. It is in a shot along with tetanus and diphtheria vaccines. The combo shot is recommended for adults every 10 years.

“They used to call it the 100-day cough because it literally lasts for 100 days,” said Joyce Knestrick, a family nurse practitioner in Wheeling, West Virginia.

Whooping cough is usually seen mostly in infants and young children, who can develop serious complications. That’s why the vaccine is recommended during pregnancy, to pass along protection to the newborn, and for those who spend a lot of time with infants.

But public health workers say outbreaks this year are hitting older kids and teens. In Pennsylvania, most outbreaks have been in middle school, high school and college settings, an official said. Nearly all the cases in Douglas County, Nebraska, are schoolkids and teens, said Justin Frederick, deputy director of the health department.

That includes his own teenage daughter.

“It’s a horrible disease. She still wakes up — after being treated with her antibiotics — in a panic because she’s coughing so much she can’t breathe,” he said.

It’s important to get tested and treated with antibiotics early, said Dr. Kris Bryant, who specializes in pediatric infectious diseases at Norton Children’s in Louisville, Kentucky. People exposed to the bacteria can also take antibiotics to stop the spread.

“Pertussis is worth preventing,” Bryant said. “The good news is that we have safe and effective vaccines.”

Alabama man arrested in SEC social media account hack that led the price of bitcoin to spike

Published

 on

 

WASHINGTON (AP) — An Alabama man was arrested Thursday for his alleged role in the January hack of a U.S. Securities and Exchange Commission social media account that led the price of bitcoin to spike, the Justice Department said.

Eric Council Jr., 25, of Athens, is accused of helping to break into the SEC’s account on X, formerly known as Twitter, allowing the hackers to prematurely announce the approval of long-awaited bitcoin exchange-traded funds.

The price of bitcoin briefly spiked more than $1,000 after the post claimed “The SEC grants approval for #Bitcoin ETFs for listing on all registered national securities exchanges.”

But soon after the initial post appeared, SEC Chairman Gary Gensler said on his personal account that the SEC’s account was compromised. “The SEC has not approved the listing and trading of spot bitcoin exchange-traded products,” Gensler wrote, calling the post unauthorized without providing further explanation.

Authorities say Council carried out what’s known as a “SIM swap,” using a fake ID to impersonate someone with access to the SEC’s X account and convince a cellphone store to give him a SIM card linked to the person’s phone. Council was able to take over the person’s cellphone number and get access codes to the SEC’s X account, which he shared with others who broke into the account and sent the post, the Justice Department says.

Prosecutors say after Council returned the iPhone he used for the SIM swap, his online searches included: “What are the signs that you are under investigation by law enforcement or the FBI even if you have not been contacted by them.”

An email seeking comment was sent Thursday to an attorney for Council, who is charged in Washington’s federal court with conspiracy to commit aggravated identity theft and access device fraud.

The price of bitcoin swung from about $46,730 to just below $48,000 after the unauthorized post hit on Jan. 9 and then dropped to around $45,200 after the SEC’s denial. The SEC officially approved the first exchange-traded funds that hold bitcoin the following day.
