Polio largely vanished thanks to vaccines. So why is it now back in more countries? – CBC News

Published

Polio, a potentially disabling virus that’s long been forgotten in many parts of the world, is now circulating in parts of the U.S. and U.K., on the heels of an outbreak in Israel — prompting health officials to launch vaccination campaigns to ensure the public is protected.

Even in Canada, a country free of polio for the last two decades, medical experts say it’s a wake-up call that the virus still poses a threat to anyone who remains unvaccinated, given polio’s ability to spread through global travel networks and wastewater systems.

On Wednesday, British health authorities announced they will offer a polio booster dose to children aged one to nine in London, after finding evidence the virus has been spreading in multiple regions of the capital. Britain’s Health Security Agency said polio virus samples were found in sewage water from eight boroughs of London, but there were no confirmed infections.

Still, the agency’s analysis showed transmission has likely “gone beyond a close network of a few individuals.”

“We know the areas in London where the poliovirus is being transmitted have some of the lowest vaccination rates,” said Dr. Vanessa Saliba, a consultant epidemiologist at the U.K. Health Security Agency.

A health official in New York State says hundreds of people could be infected with the polio virus.

The agency said it was working closely with health authorities in the U.S. and Israel, as well as the World Health Organization, to investigate the links between polio viruses detected in those two countries. 

In July, Israel announced a recent outbreak of polio infections appeared to be under control, after multiple people became infected, including a Jerusalem girl who was paralyzed and now requires rehabilitation, according to the Jerusalem Post.

More recently, in the state of New York, one unvaccinated young adult suffered paralysis after a polio infection in Rockland County — an area known for low vaccination rates — which marked the first case reported in the U.S. in nearly a decade. 

Vaccination campaigns are now underway as samples of the virus were also detected in the wastewater of both Rockland and another county, just north of New York City. Officials also say hundreds more people may already be infected.

“The scope may be even much larger than we can even fathom or imagine,” said New York-based immunologist Dr. Purvi Parikh.

“Because vaccines have become the victim of their own success, we don’t see it — so we may not even realize what the spread of polio is, because for the majority of us who are vaccinated, it doesn’t really [affect] us.”

Outbreaks do still happen in certain countries

Before mass vaccination campaigns largely wiped out polio from circulation in higher-income countries like Canada between the 1950s and early 1990s, the virus was known for sparking outbreaks and striking children, causing paralysis or death in some cases.

Even now, war, poverty, and social unrest make it difficult to achieve eradication in many countries around the world. Outbreaks remain common in Afghanistan, Pakistan, and parts of Africa.

Parikh said polio cases aren’t entirely a surprise in any community where vaccination rates are lower, either due to anti-vaccine sentiments or disruptions to routine immunizations during the COVID-19 pandemic.

“Now the concern is, some of these infectious diseases that we haven’t seen in nearly decades may actually come back and pose to be a problem,” she said.

Part of the challenge in wiping polio out around the world actually comes from the vaccination approach used in certain regions. While higher-income countries now use an inactivated poliovirus vaccine given as a traditional shot, others rely on a weakened poliovirus that’s easy to administer by mouth.

Both types of vaccines helped curb global transmission and, crucially, neither one is capable of giving someone a case of symptomatic polio.

However, since the oral version winds up in the stomach, it’s eventually flushed out of the body into wastewater systems — where, over time, the virus can evolve back into a form that’s able to cause disease.

“So if you have a shedding of that particular virus and transmission of that in a community, it can cause a polio outbreak,” said Dr. Isaac Bogoch, an infectious diseases specialist with the University Health Network in Toronto.

“And in fact, if you look at many parts of the world, there have been small outbreaks of vaccine-derived polio.”

‘Polio is only a plane trip away’

Lab testing conducted on the case in New York, for instance, linked the virus samples to transmission from someone who’d received the oral vaccine, which hasn’t been used in the U.S. since 2000. “This suggests that the virus may have originated in a location outside of the U.S. where [the oral vaccine] is administered,” officials said.

In London, out of more than 100 polio samples identified in sewage, most were vaccine-like virus, according to the UK Health Security Agency, while others had enough mutations to be more like “wild” polio that can cause serious health impacts.

Global travel between countries with high rates of polio transmission and regions with lagging vaccination rates could pose a problem going forward, said Wes Hazlitt, a Winnipeg polio survivor, advocate, and president of the Post-Polio Network in Manitoba.

“Polio,” he added, “is only a plane trip away.”

Another challenge in tackling outbreaks stems from this virus’s ability to spread undetected, experts say, with most people unaware they’re even infected — leaving countries vulnerable to slow-growing outbreaks before any patients show up with major disease and paralysis.

“Most people will have no symptoms or mild symptoms, but about one in 200 or so will have significant symptoms,” Bogoch said.

Under-vaccinated communities remain at risk

So when it comes to experiencing a future polio outbreak, how at risk is Canada? That all depends on vaccination rates both now and in the future, multiple medical experts said.

“If you start not vaccinating the kids from the primary series — like the measles, mumps, rubella, diphtheria, tetanus, pertussis, polio — then you risk those diseases coming back,” warned Dr. Anna Banerji, a pediatrician and infectious disease specialist in Toronto.

A vast majority of the Canadian public has been vaccinated against polio, and while immunization rates among children ebb and flow, the latest available federal data from 2017 shows roughly 90 per cent of toddlers had all three required polio shots. 

But that coverage isn’t uniform across the country. Polio vaccination rates were below 90 per cent in British Columbia and Manitoba, and close to just 80 per cent in Nunavut, while uptake in specific communities can vary and may have been disrupted by COVID-19 school closures.

Polio wards were lined not only with beds but with iron lungs, large metal ventilators that helped patients to breathe during the worst of the infection. Some survivors never regained lung function and spent the rest of their lives in the devices. (U.S. Food and Drug Administration)

“We do have our issues in Canada, with under-vaccinated communities for a variety of reasons, and a lot of this predates COVID-19,” said Bogoch, adding many public health teams across the country did offer immunization programs throughout the pandemic to get children caught up.

While pockets of the population could remain vulnerable to polio infection, Fatima Tokhmafshan, a researcher and geneticist at the Research Institute of the McGill University Health Centre, said most Canadians shouldn’t be overly concerned.

“If you see something circulating, it’s good to be on your guard, but not panicking,” she said. 

“So it’s important to keep an eye out. And reach out to your network, to your friends, your family — make sure everybody’s vaccinated.”

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.”
