The BA.2 subvariant of Omicron has quickly become the dominant strain of Covid-19 in New Zealand. What is it and what impact will it have on the current outbreak? RNZ is here to clear it all up.

Over time viruses change and mutate, creating new variants and subvariants. As we know, there are a number of variants of Covid-19, each given their own letter of the Greek alphabet like Beta, Delta and Omicron. BA.2 is one of several subvariants of the Omicron variant of Covid-19 – not quite unique enough to be given its own letter, though whether it should still have one is debatable.

When you think about Omicron, until now it was likely you’re thinking about BA.1, which was dominant in most Omicron outbreaks until recently. BA.1 and BA.2 have differences in genetic sequence, including amino acids and proteins.

BA.2 was first detected in November 2021, around the same time as BA.1 but by mid-March 2022, BA.2 was rapidly gaining momentum around the world.

First found in New Zealand in late-January when a number of border workers and close contacts tested positive, as of mid-March, nearly 80 per cent of recent cases that had undergone genomic sequencing here were found to be the BA.2 subvariant.

Though with rapid antigen tests now the dominant form of testing in New Zealand, genomic sequencing is less common than it once was and so it is impossible to know just how widespread a variant is at any one time.

It’s highly unlikely you will know whether you’ve tested positive for BA.1 or BA.2 if you’ve tested positive for Covid-19.

Director general of health Dr Ashley Bloomfield says the prevalence of BA.2 was part of the reason why case numbers in Auckland during the peak of the Omicron outbreak were higher than modelling predicted.

What does this mean for the Omicron outbreak?

While it may prolong the Omicron surge, it’s unlikely the rise in BA.2 cases would result in a large second wave as some countries are dealing with, Otago University virologist Dr Jemma Geoghegan told Morning Report.

In fact, she says, seeing a rise in BA.2 at the same time as BA.1 is the best possible scenario and having this happen at the end of summer and among a highly vaccinated population was an advantage too.

Bloomfield says if the majority of cases in New Zealand’s outbreak were BA.2 it could act in the country’s favour.

He says some places such as New South Wales, the UK and particularly Scotland – were seeing second outbreaks with the BA.2 subvariant, having already had BA.1 subvariant outbreaks.

“Even those jurisdictions that had an initial quite big Omicron outbreak are getting a second one, that seems to be associated with the BA.2 subvariant.”

If most of New Zealand’s Omicron cases are already the BA.2 subvariant, Bloomfield says there is a chance “we will miss that second big peak again that other countries are seeing”.

That’s what has happened in Denmark, which saw a rise in BA.2 during its first Omicron wave.

Is it more transmissible?

It’s estimated BA.2 is up to 40 per cent more transmissible than the already highly transmissible BA.1.

A study of 8,500 households and 18,000 individuals conducted by Denmark’s Statens Serum Institut (SSI) found that BA.2 was “substantially” more transmissible than BA.1, though it’s important to note this has not yet been peer reviewed.

A separate UK study also found higher transmissibility for BA.2 compared to BA.1.

Data is still limited but the World Health Organisation says people have been reinfected with BA.2 after having had an infection of BA.1.

“Data suggests that antibodies from past BA.1 infection does give you some protection against BA.2, although clearly reinfections can happen, they’re probably more rare,” Geoghegan says.

Is it more severe?

Bloomfield says while BA.2 is more transmissible, there is currently no evidence to suggest it is more or less severe.

A risk assessment report from Denmark’s SSI in late-February found there wasn’t an increased risk of hospital admission associated with BA.2 compared to BA.1. And that’s what researchers in England found too.

How effective are vaccines against BA.2 ?

Vaccines appear to effectively shield people against the highly transmissible BA.2, Geoghegan says.

“The real-world data suggests there’s no difference in disease severity between the two variants and the vaccine and boosters appear to be providing really good protection against both subvariants as well.”

Health officials in England reported the vaccine was similar in effectiveness against symptomatic disease for both BA.1 and BA.2.

Pfizer boss Albert Bourla told CBS the company is currently trying to make a vaccine that would protect against all variants, and last up to a year.

Both Pfizer and Moderna think a fourth dose of their Covid-19 vaccines – a second booster shot – is necessary as the protection from earlier doses wanes.

How is a new variant found?

PCR testing continues to be used in hospital settings and at the border as part of New Zealand’s surveillance regime, allowing officials to detect new variants in the country – this surveillance testing is how officials know BA.2 is on the rise here.

Prime Minister Jacinda Ardern wants New Zealand to become “really sufficient” at surveillance at the border, “gold standard,” she says.

Auckland University’s Dr David Welch says the border reopening has increased the need for better testing for the virus to guard against new variants.

Can we expect more variants (or subvariants) in the future?

New variants of Covid-19 pop up all of the time and have done since the beginning of the outbreak, whether of not they become a ‘variant of concern’ is decided by the World Health Organisation. The subvariants of Omicron are currently being monitored by WHO.

“With less stringent border restrictions we expect to see new lineages of viral genomes – genomics enables us to watch these closely,” the Institute of Environmental Science and Research’s principal scientist and genomics lead Professor Mike Bunce and lead bioinformatics and genomics, Dr Joep de Ligt say in a joint statement.

“Hospital cases are a priority for genome sequencing. The genomic surveillance plan also calls for multiple samples to be taken from patients that have a prolonged infection with Covid-19. The risk here is that the virus, if not ‘cleared’, can accumulate mutations; we can monitor this by taking samples over time and seeing if key parts of the virus (such as the spike protein) are changing,” they say.

“New variants can also emerge in long-haul (long Covid) patients, and there is an increasing awareness of this on the international stage.”

Dr Welch says MIQ gave New Zealand a “real time buffer and that time buffer has allowed us to plan to prepare”.

“If we can detect something at the border then you know it would still have to grow inside New Zealand and spread, so spotting at the border rather than once it’s already spread widely, could give us a … two or four weeks heads-up.”

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.”
