Calling COVID-19 airborne is misleading, Canadian experts say – CP24 Toronto's Breaking News

Published

 on


A group of 239 scientists and physicians urging the World Health Organization to recognize the potential for airborne transmission of the novel coronavirus have sparked debate over how COVID-19 is spreading.

But some Canadian infectious disease experts say not to get hung up on the term “airborne,” and that the safety precautions we’re already taking to slow the spread of the virus are working.

“To the general public the word (airborne) can be pretty confusing because it suggests that COVID is gonna come through the keyhole and get you in your sleep. And well, it isn’t,” said Colin Furness, an epidemiologist with the University of Toronto.

“No one is suggesting COVID behaves anything like measles. … That’s not the point (the scientists) are trying to make.”

In an open letter to the WHO published Monday, scientists across 32 countries called for the organization to revise its safety recommendations to mitigate possible spread of COVID-19 through aerosols – tiny, light particles expelled when people cough, sneeze or breathe that stay suspended in the air for longer periods of time.

The WHO currently classifies SARS-CoV-2 as a droplet virus, spreading through larger, heavier particles that can travel one to two metres before hitting the ground.

Furness says WHO is right, according to how we’ve seen COVID spread in clinical practice, but the scientists behind the letter have a point, too.

He said people release particles of all sizes when they breathe, and SARS-CoV-2 can be found in smaller droplets. But that doesn’t mean they are effective in trasmitting the virus, he added.

The scientists’ letter mentions a COVID-19 outbreak at a Chinese restaurant where customers at tables further than two metres apart became infected. While the authors use that as an argument for COVID’s spread through aerosols, Furness said that’s not necessarily the case.

“It could be (evidence of aerosol spread) but it also could be that they touched the same thing. We don’t know,” he said. “Also one would need to explain why didn’t everyone in the restaurant get sick?”

“So WHO is right that there isn’t a clear case. And the scientists who signed that letter are right saying we do need to look at this … because it could have an impact on what we say is safe.”

Dr. Bonnie Henry, B.C.’s provincial health officer, praised WHO on Monday for “doing an amazing job trying to keep up with what’s going on,” and said she thought the scientists’ letter was “trying to foment a bit of controversy.”

Henry added that while COVID does seem to be released in small droplets as well as large droplets, we don’t know how potent those smaller particles are.

“Where there’s some challenges is how much is due to the small aerosols which are transmitted when I’m close to you, or the larger droplets that tend to fall out more readily,” Henry said. “So it’s really a bit of nuance, I think.”

Dr. Zain Chagla, an infectious disease physician and an associate professor at McMaster University in Hamilton, doesn’t believe the novel coronavirus is transmitting through aerosols, at least not to an extent we should be worried about.

If it was “we’d be in trouble,” he said.

“We would have seen huge rates of transmission if this was a predominantly aerosol virus. We would have not been able to control it as well as we did.

“In reality, there is probably some degree of small aerosols that would carry COVID-19 in average day-to-day contact, but it’s probably very minimal.”

Chagla also believes the argument for aerosol versus droplet transmission is “more of a discrepancy on the exact scientific terminology” of what airborne actually means.

COVID-19 does have the potential to transmit through small particles when patients in hospital are undergoing “aerosol-generating procedures” like being intubated, Chagla said, and WHO also acknowledges that.

In those instances, health-care workers are given proper personal protective equipment (PPE), including N95 masks, which protect against small airborne particles.

But Chagla highlighted a specific case from early in the pandemic, before evidence of community spread, when health-care workers treated a COVID patient in California without proper PPE. Out of 121 health-care workers that treated the patient and performed “multiple aerosol-generating procedures,” only three got sick.

“So you had 118 individuals that … did not wear N95 masks which would be the only protection against aerosol viruses, and they did not get infected,” he said.

Chagla compared the situation to measles, which has a reproduction number of about 18 – meaning one infected person will infect 18 others. Measles particles can stay suspended in the air of a room for hours after an infected person leaves it, Chagla said, and you can catch the virus from a much further distance away.

COVID-19 has a reproduction number of two, Furness said, which is larger than other coronaviruses (0.5 for SARS and 1.5 for H1N1).

So that could mean there’s more going on.

“COVID is doing something to be more infective than your average respiratory virus,” Furness said. “And I’m nowhere near saying it’s airborne, because I don’t think that’s an appropriate statement. But I think those aerosols, those smaller droplets that we’re disregarding, they might be important.”

Both Furness and Chagla say there’s no indication that the general public will need to do any more to protect from potential aerosol spread of the virus.

Chagla says the points emphasized by the scientists in the letter mirror what we’re already doing, like having events outdoors rather than indoors to ensure proper air flow.

Face coverings become more important if we have to worry about aerosols, Furness says. And even though smaller particles can get through cloth masks, the fabric will slow them down and provides some protection for those around the wearer.

“The more we can slow down the trajectory of what comes out of your mouth, the less it disperses,” he said. “As for physical distance of two metres, maybe we should think about increasing it, although there’s not a lot of evidence we should.”

Furness says there had been “a really sharp line in the sand – up until a day or so ago,” that put COVID-19 on the droplet side of virus transmission, and things like measles and small pox on the airborne side.

But now, people are looking more into the “grey area” in the middle.

“What these scientists are saying is that the WHO and a lot of infection prevention folks around the world have drawn the line in the wrong place. … and in fact, the line is a problem,” Furness said. “It’s better to look at droplets as a continuum and we should (recognize) that some droplets can be smaller and lighter, and spread farther for longer then what we’re used to with fat droplets.

“And if that’s true, and they’ve got some evidence – be it very circumstantial – then it’s worth looking at.”

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.”
