Delta variant exploits low vaccine rates, easing of rules – Toronto Star

Published

 on


The latest alarming coronavirus variant is exploiting low global vaccination rates and a rush to ease pandemic restrictions, adding new urgency to the drive to get more shots in arms and slow its supercharged spread.

The vaccines most used in Western countries still appear to offer strong protection against the highly contagious delta variant, first identified in India and now spreading in more than 90 other countries.

But the World Health Organization warned this week that the trifecta of easier-to-spread strains, insufficiently immunized populations and a drop in mask use and other public health measures before the virus is better contained will “delay the end of the pandemic.”

The delta variant is positioned to take full advantage of those chinks in any country’s armor.

“Widespread vaccination remains even more critical, because the virus that we have circulating is in fact more transmissible than the original wild type,” said Dr. Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention.

Amid concerns about the variant’s spread, parts of Europe have reinstated travel quarantines, several Australian cities are in outbreak-sparked lockdowns — and just as Japan readies for the Olympics, some visiting athletes are infected. The mutation is causing worry even in countries with relatively successful immunization campaigns that nonetheless haven’t reached enough people to snuff out the virus.

For instance, the mutant has forced Britain, where nearly half the population is fully vaccinated, to postpone for a month its long-anticipated lifting of COVID-19 restrictions, as cases are doubling about every nine days.

In the U.S., “we’re still vulnerable for these flare-ups and rebounds,” said Dr. Hilary Babcock of Washington University at St. Louis.

The variants “are able to find any gaps in our protection,” she said, pointing to how hospital beds and intensive care units in Missouri’s least-vaccinated southwestern counties suddenly are filling — mostly with adults under 40 who never got the shots. With nearly half the U.S. population immunized, CDC tracking shows the variant spreading most quickly in swaths of the country with the lowest rates.

But the variant poses the most danger in countries where vaccinations are sparse. Africa is seeing cases rise faster than ever before, partially driven by the mutation, the WHO said Thursday, while areas in Bangladesh that border India are also seeing a variant-fueled surge. Fiji, which got through the first year of the pandemic without just two virus deaths, is now experiencing a significant outbreak blamed on the strain, and Afghanistan is desperately seeking oxygen supplies because of it.

The delta variant remains far from the only version of the coronavirus that’s spreading — and you don’t want to catch any kind. Here’s what scientists know so far:

EASIER SPREAD IS THE CHIEF THREAT

Scientists believe the delta variant is about 50% more transmissible than other types. Researchers are just beginning to tease apart why. But there are early clues that some mutations may ease a key step in how the virus slips inside human cells, said Priyamvada Acharya, a structural biologist at the Duke Human Vaccine Institute.

Still, it’s not clear if higher contagion is the whole reason the variant is spreading so quickly. In Britain, its rise followed a loosening of restrictions in May, when restaurants, gyms and other businesses reopened, and thousands of fans have attended sports events.

IS IT MORE DANGEROUS?

It’s harder to tell if the delta variant makes people sicker. British experts have said there are some preliminary signs it may increase hospitalization, but there’s no evidence it is more lethal.

It fueled a devastating COVID-19 surge in India in February, and “this time around we had a lot more people who were very sick compared to before,” said Dr. Jacob John of Christian Medical College at Vellore. But he cautioned that the “explosion” of cases didn’t necessarily mean this version was more dangerous, as more cases usually mean more hospitalizations.

THE BEST PROTECTION IS FULL VACCINATION

British researchers found two doses of either the Pfizer-BioNTech vaccine or the AstraZeneca one were only slightly less effective at blocking symptomatic illness from the delta variant than from earlier mutations — and importantly, remain hugely protective at preventing hospitalization.

Loading…

Loading…Loading…Loading…Loading…Loading…

But there’s an important catch: Just one dose proved far less effective against the delta variant than against earlier versions of the virus. That has prompted Britain, which originally extended the gap between doses, to speed up second shots.

There’s little information on whether the delta variant can escape other vaccines, such as ones developed in China or Russia.

Experts say the Moderna vaccine, the same type as Pfizer’s, should be similarly protective. Johnson & Johnson still is studying how its one-dose vaccine fares against the variant. The company notes its shot does protect against a different worrisome mutant — the so-called beta variant that emerged in South Africa and is still considered the biggest challenge for today’s COVID-19 vaccines.

WHAT ABOUT MASKS?

The WHO has urged governments not to lift pandemic restrictions too quickly — including saying everyone, even the vaccinated, should continue to wear masks given that the delta variant spreads more easily and no vaccine is 100% effective.

In the U.S., the CDC says the fully vaccinated can go mask-free. But there’s no way to know if maskless people really are vaccinated and local governments can set tighter guidelines. This week, with the delta variant spreading locally, health officials in Los Angeles County said they still recommend masks indoors in public places for everyone.

If that’s confusing, consider that the more the virus is spreading in a particular area, the more risk even the vaccinated have of getting a mild or asymptomatic infection they could spread to someone not protected — such as children too young to qualify for the shots.

In Missouri, fully vaccinated Babcock makes sure she has a mask to pop on quickly if she runs into a crowd: “I feel like my new normal is holding a mask in my hand, ready to put it on if I need it.“

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.”
