Virus behind COVID-19 spreads quickly and mutations make it unpredictable: experts – Saanich News

Published

 on


Putting an end to the COVID-19 pandemic will mean priming the immune systems of everyone on Earth but the virus is spreading quickly and may take years to “settle down,” says an infectious disease specialist.

Just as some scientists started to voice the idea that COVID-19 might have reached the peak in its evolution with Delta and people began taking steps to learn how to live with the virus, a new variant struck. Omicron has been identified in several parts of the world.

Dr. Isaac Bogoch, an infectious diseases specialist at the University of Toronto, said while vaccines are extremely important, strong political leadership and policy is what will help bring COVID-19 under control, a strategy reinforced by the emergence of the Omicron variant.

“I’m just guessing here, but what’s likely going to happen is this virus is not going to go away for a long, long, long time,” he said in an interview.

Prof. Mark Brockman, a virologist at Simon Fraser University, said COVID-19 takes over human cells and instructs them to make more viruses. Sometimes errors or typos occur in the duplication process, producing new variants.

“There’s been so many people around the world who have been infected with the virus, that we’ve given it a lot of opportunity to make mutations, and even very, very rare mutations,” he said.

Coronaviruses don’t mutate as quickly as others, Brockman said, noting hepatitis C and HIV change much more readily.

But that slower rate of evolution is offset by worldwide infections, giving the virus millions of chances to become more transmissible, he noted.

“It has been a little bit surprising at the population level that the variants have arisen and spread so, so easily or so quickly,” Brockman said.

“We hadn’t anticipated that the virus would have spread so quickly, so widely to so many people.”

While it’s “important for people to know that we won’t have to live with various public health restrictions forever,” Bogoch said it’s hard to predict anything further than about two months into the future.

Scientists and researchers look at other respiratory viral pandemics for an estimate on how long COVID-19 could stick around.

“I’d guess the pandemic would last for a total of two to four years, and then we would start seeing things settle down, depending on what country you live in. But this isn’t influenza,” Bogoch said.

“So, I mean there’s some lessons that I think we can learn from other pandemics, but we also have to recognize that this is not the flu and it might behave a little bit differently.”

A statement from the World Health Organization said the opportunity to eradicate the virus is largely gone.

“We are moving toward the virus becoming endemic, which means it will stay with us,” it said.

“There is no formal definition or cutoff point at which an outbreak is considered a pandemic or ceases to be one, so this is not a simple question to answer.”

A pandemic is defined as a global spread of a disease that is either new or occurring well above normal levels, it said.

“At this moment, WHO considers that COVID-19 continues to be a pandemic. If we are able to bring and keep the spread of the disease down and avoid the large number of deaths we are currently witnessing, we can move beyond the pandemic stage.”

Christopher Rutty, a medical history professor at Dalla Lana School of Public Health at the University of Toronto, said smallpox elicited debates about vaccination, while polio, like COVID-19, demonstrated the importance of political leadership.

The Spanish flu “sort of petered out,” evolved into less severe strains and became more seasonal, he added.

“But COVID, this is new. This is uncharted territory,” Rutty said.

“You can look back at different diseases, but there’s a lot of differences in economics and the politics of different times and how people move around. If some people aren’t being fully vaccinated, then there are viruses still getting around and people are travelling and so that’s what makes it hard to see the end.”

Prof. Sarah Otto, an evolutionary biologist at the University of British Columbia, said the virus could evolve in combinations of mutations that “give it a fitness advantage,” helping it transmit faster or make it more dangerous, which is what Omicron appears to have done.

The unusual thing about this virus is that it is a “generalist,” allowing it to easily move between species, Otto said.

The virus has now been able to spread to a number of animals including household pets, hippopotamus, big cats, primates and mink. The Canadian government announced that the COVID-19 virus was found in white-tailed deer in Quebec in early December.

“Animal reservoirs mean that we won’t be able to eradicate SARS-CoV-2 because it’s now in enough animals that it will circulate there and come back to us,” she said.

There are a number of unknowns with such infections, including which animals pose the biggest risk of transferring the disease back to humans, Otto said.

The other concern with COVID-19 is it can go undetected with the infected person showing no symptoms for long periods, she said.

Vaccines are expected to have taught our immune systems to recognize the spike protein made by the virus, despite the many changes in Omicron, she said.

Otto said the “cool thing” about the human immune system is that it is not a one-size-fits-all reaction, rather a number of cells and antibodies are made that recognize lots of different parts of viruses and bacteria.

While the evolution of organisms never stops, priming the immune system with vaccinations makes it hard for the COVID-19 virus to infect the body, Otto said.

“It’s like hundreds of little hammers, hitting hundreds of nails in hundreds of different places.”

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.”
