From mu to C.1.2, here are the latest coronavirus variants scientists are watching closely – CBC.ca

Published

 on


Scientists have warned the coronavirus will keep evolving as it spreads around the world, and there are now multiple new variants being watched closely by global research teams.

One of those, B.1.621, also known as mu, has been dubbed the latest variant of interest by the World Health Organization (WHO). Another, C.1.2, is the subject of headline-making new research exploring how it behaves. Other variants are likely waiting in the wings, yet to be detected.

So why do these new variants matter, what are they capable of, and how much should Canadians care?

Right now, the highly-contagious delta variant — deemed a variant of concern by the WHO back in May — is dominating Canada’s COVID-19 cases, making up more than 90 per cent of reported recent infections according to federal data.

But that doesn’t mean other emerging variants don’t warrant close observation. 

“Looking at this virus, it’s obvious that we will have new variants,” said Alyson Kelvin, a virologist at the Vaccine and Infectious Disease Organization (VIDO) at the University of Saskatchewan. 

“What we need to do is to be ready for identifying cases … as well as other variants that are inevitably going to start emerging around the world.” 

Here’s what Canadians need to know:

What is the B.1.621 — or mu — variant?

B.1.621 is the latest variant of interest, according to the WHO, and was given the designation — and a catchier Greek alphabet-based name, “mu” — on August 30.

“The mu variant has a constellation of mutations that indicate potential properties of immune escape,” reads the WHO’s latest weekly epidemiological update.

That means those with some level of immunity to earlier strains, either by previous infection or vaccination, might be susceptible to infection from mu — but that’s only according to preliminary data and “needs to be confirmed by further studies,” the update continued.

The variant was first detected in Colombia back in January, and since then, the country has experienced hundreds of cases and the variant has also been reported in 39 other countries around the world.

Here in Canada, it’s barely making a splash: Mu cases have been reported for weeks, but so far, the variant hasn’t made up more than three per cent of cases in any given week and recently totalled just 0.3 per cent — though federal data since mid-July is still accumulating and could change.

What is the C.1.2 variant?

The variant C.1.2 isn’t deemed a variant of interest or concern yet by the WHO, but researchers are pushing the organization to watch it closely.

A team of scientists from South Africa detected the new variant, which was first observed in May and has since spread to seven other countries in Africa, Europe, Asia and Oceania, according to a preprint study that hasn’t yet been peer-reviewed.

“It’s still not clear where this came from,” noted Dr. Zain Chagla, an infectious diseases specialist with McMaster University in Hamilton. “It was first identified in South Africa but people need to know that South Africa has actually quite good sequencing networks and so it may not be the origin.”

Richard Lessells, an infectious disease specialist and one of the authors of the research on C.1.2, told Reuters the variant may have even more immune-evasion properties than delta, based on its pattern of mutations, and that the findings had been flagged to the WHO.

However, it’s not known yet if the variant is actually more contagious, or more capable of evading the immunity provided by either vaccines or a prior coronavirus infection.

“These things need time to see,” Chagla said. “Delta is incredibly fit, and incredibly virulent and replaces [other strains] aggressively. We still haven’t seen suggestions of this yet [with C.1.2].”

How worried should Canadians be right now?

Given that delta makes up the lion’s share of Canada’s COVID-19 cases and there’s still much we don’t know about mu or C.1.2 — concerns over emerging variants need to be put into context.

Chagla said it’s important to keep studying and monitoring the C.1.2 variant, but “there’s no need for panic yet.”

There has been an increased spread of C.1.2, and it’s a rising percentage of sequenced cases in various countries outside of South Africa, Chagla said, but nothing on the scale of delta and it remains to be seen if we’ll experience more global spread. 

“It’s still not clear whether or not that just means there’s a lot of local spread amongst particular groups that just seems to be over-represented — or if it’s a legitimate growth pattern,” he added.

“We still don’t know, if you put things in the same pool, whether or not delta is going to be much more virulent.” 

Chagla says that much like other variants that have emerged over the course of the pandemic — including variants of concern like alpha, beta, lambda and, now, mu — they could either be overtaken by delta or “burn themselves out over time.” 

“Right now, it seems that there aren’t a large number of cases for [C.1.2],” Kelvin said. “But now that we have this identified, then surveillance centres around the world can start to determine, are they seeing numbers of these cases as well?” 

To figure out how often variant cases are appearing here, the Public Health Agency of Canada works with the provinces, territories, and the Canadian COVID-19 Genomics Network to sequence a percentage of all positive COVID-19 test results.

Sequencing reveals the genetic code of the virus, showing which variant was involved in a specific case of COVID-19, and those results are reported each week




Why do new variants matter in the global fight against COVID-19?

New variants have emerged throughout the pandemic in populations with low vaccine coverage that have been hit hard by unchecked COVID-19 transmission — including India, South America and Africa — and experts say this trend is likely to continue until more of the world is vaccinated.

“This is an incredibly big reminder — even if this is a false alarm — of what global vaccine equity means,” said Chagla. 

“Many of us starting to see the delta wave in Sub-Saharan Africa were very, very worried about what could come of that.”

People in wealthier countries are getting vaccinated at a much faster rate than those in poorer countries despite efforts by the World Health Organization and the international community to make COVID-19 vaccine accessibility equitable around the world. 2:04

Chagla says the region has low vaccination levels, poor quality healthcare systems and a large population of immunocompromised individuals, with rates of HIV in some countries as high as 15 to 20 per cent of the adult population.

“That was kind of a mixing pot of bad scenarios to lead to the development of a variant … so I don’t think we can be surprised to see that something seems to have shown up,” he said. 

“And we kind of just watch it happen in that sense, and we continue to watch it happen.”

It’s also clear these variants don’t stay put.

Even if they emerge in one area of the world, cases later appear elsewhere — meaning other countries, including Canada, are eventually impacted yet again by this ever-evolving virus.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
