Why the WHO won't say the coronavirus is airborne and driving the pandemic – CBC.ca

The World Health Organization has refused to cave to pressure from more than 200 experts calling for it to update its messaging on the threat of the spread of the coronavirus through the air, citing a lack of “definitive” evidence. 

In an open letter first published by The New York Times on Saturday, 239 scientists from 32 countries called on the United Nations agency to acknowledge that airborne transmission of the coronavirus is a potential driver of the pandemic. 

But the WHO stopped short of revising its messaging Tuesday. 

“These are fields of research that are really growing and for which there is some evidence emerging but is not definitive,” Benedetta Allegranzi, WHO’s technical lead for infection prevention and control, said during a briefing in Geneva Tuesday. 

“The possibility of airborne transmission in public settings — especially in very specific conditions: crowded, closed, poorly ventilated settings that have been described — cannot be ruled out. However, the evidence needs to be gathered and interpreted.” 

How big of a threat is the coronavirus through the air? 

It’s widely accepted that COVID-19 spreads from both symptomatic and asymptomatic carriers through respiratory droplets, although the WHO previously backtracked on its messaging around the significance of those without symptoms. 

What the group of international scientists is drawing attention to is the role that smaller, microscopic droplets could play in spreading virus particles when people are talking, singing or breathing. 

Studies of so-called superspreading events or locations, such as a choir practice in Washington state, a call centre in South Korea and a restaurant in China have supported the conclusion that some degree of transmission is occurring through the air, and experts say it should not be discounted.

“The risk of ignoring airborne transmission is that the disease will continue spreading rapidly as we’ve seen,” said Linsey Marr, an expert in the transmission of viruses by aerosol at Virginia Polytechnic Institute and State University, known as Virginia Tech, in Blacksburg, Va., and a signatory of the letter. 

But the exact extent to which it plays a role in the spread of COVID-19 is still unclear. 

“We just don’t know,” Marr told CBC News. “It seems clear that all of these routes could be happening, and given the scale of the pandemic, I think it’s wise for us to do as much as we can to slow down or interrupt all of these different routes.” 

She said people need to place more emphasis on the public health measures we’re already taking in order to stop the potential spread of airborne transmission.

That includes adhering to physical distancing, wearing a mask when necessary, increasing ventilation indoors and moving activities outdoors whenever possible in order to prevent airborne particles from building up.

Maria Van Kerkhove, WHO’s technical lead on the pandemic, said the agency would be releasing a scientific brief in the coming days that will outline its position on all different modes of transmission — including airborne, droplets, surfaces and fecal-to-oral.

“We have been talking about the possibility of airborne transmission and aerosol transmission as one of the modes of transmission of COVID-19,” she said during the press conference Tuesday.

The WHO’s guidelines on airborne transmission are primarily focused on hospitals, she said.

“But we’re also looking at the possible role of airborne transmission in other settings, particularly close settings where you have poor ventilation.” 

That statement doesn’t go far enough for the experts behind the letter, who went public because, they say, they felt there is enough evidence for the WHO to change its messaging to better inform the public about the potential threat of the virus through the air.

“We were frustrated that they were very dismissive of the evidence,” said Jose Jimenez, a professor of chemistry at the University of Colorado specializing in aerosol science who also signed the letter. 

“They don’t really have really certain evidence about any of the modes of transmission, whether it goes through contacts, through objects or through droplets — there is no more evidence for those sources of transmission than there is for aerosol.” 

‘No new data’ to make conclusive decision

But that level of uncertainty over how big a role airborne transmission plays has also led some infectious disease experts to question the push to label it a significant threat before all the research is in, backing up the WHO’s current position.

“It’s creating a false sense of alarm, and it doesn’t contribute to our understanding or the management of this infection,” said Dr. Isaac Bogoch, an infectious disease physician at Toronto General Hospital.

“Now, could there be some airborne transmission? Maybe a little bit, but I think it’s pretty safe to say that the vast majority of transmission falls toward the droplet end of the spectrum.”

Bogoch said the letter and subsequent article in the New York Times fractured the scientific community and caused a stir with the public over concerns whether enough was being done to address the threat of airborne transmission — but in reality, it’s nothing new. 

“This concept keeps coming up. This issue has arisen in January, and it sort of rears its head from time to time,” he said.

No new research has arisen that should lead to a definitive answer one way or the other, he said.

“There’s no new data. There’s no new information. There’s just a letter and some angry headlines.” 

B.C.’s provincial health officer, Bonnie Henry, said the controversy has been overblown.

“I actually think it’s a little bit of a tempest in a teapot in that we all agree on the extremes and we’re fussing a little bit about how much we need to focus on the bits in the middle,” she said in her COVID-19 briefing Monday.

“It is important to continue to look at the data, to look at where we’re seeing transmission events and adapt if we need to and put in additional measures.” 

Epidemiologist Ashleigh Tuite, an assistant professor in the University of Toronto’s Dalla Lana School of Public Health, said if the coronavirus spread significantly through the air, we’d know it. 

“If this was primarily aerosol based, we would have had a much harder time controlling this,” she said. 

“Given the success that we’ve had with controlling it, it really does seem like we don’t need to be overly worried about the role of aerosols in terms of spread.” 

Jimenez acknowledged that the threat of airborne transmission isn’t on par with a disease like measles, which is highly contagious through the air but said the WHO should go beyond their current messaging. 

“They’re in a very difficult position, right? I mean, they are a very important organization, and they are being asked to do a huge job with limited resources,” he said. 

“The important thing is, we’re trying to nudge them to change. If we didn’t think they were very important and their opinion matters and their guidance was valuable, we wouldn’t be bothering with trying to convince them.”

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.”
