Will herd immunity save us? Your COVID-19 questions answered – CBC.ca

We’re breaking down what you need to know about the pandemic by answering your questions. You can send us your questions via email at COVID@cbc.ca and we’ll answer as many as we can. We’ll publish a selection of answers every weekday on our website, and we’re also putting some of your questions to the experts on the air during The National and News Network.  

So far, we’ve received more than 20,000 emails from all corners of the country. Your questions have surprised us, stumped us and got us thinking.

Will herd immunity save us from COVID-19?

We are receiving a lot of questions about herd immunity, including an email from Suzanne K. who wants to know: How and when does herd immunity evolve? 

By definition, herd immunity evolves when a sufficient amount of the population becomes immune to a disease. When it comes to COVID-19, herd immunity means the virus would not be able to spread on its own, according to Erin Strumpf, a health economics expert at McGill University. 

“It’s not prevention of a disease, per se, but it’s prevention of an epidemic,” she says.

Most experts suggest herd immunity cannot be achieved safely without a vaccine, because seniors and other vulnerable populations with suppressed immune systems would be at risk, and hospitals would be overwhelmed. 

British Prime Minister Boris Johnson rolled back the U.K.’s herd immunity strategy on March 16, just four days after it was implemented. Johnson later tested positive for COVID-19 and was admitted into intensive care. He has since been released.

Watch Dr. Allison McGeer, an infectious diseases specialist, answer audience questions on The National:

Dr. Allison McGreer, infectious diseases specialist at Mount Sinai Hospital in Toronto, says herd immunity without a vaccine is “theoretically possible” if everyone, or almost everyone, who becomes infected develops antibodies that will protect them for life. 

While that might happen, “we don’t know that [yet],” said Dr. McGreer. 

“It would just be foolish to count on it, which is why we’re working on vaccines.”

How do I practice physical distancing during Ramadan?

Thanks to Aslam K. for this question. The month of Ramadan will look very different this year. This is the time when Muslims go without food or drink from sunrise to sunset every day, then gather to break their fast and pray together.

According to the Canada Council of Imams, mosques in Canada are taking their lead from health officials and their provincial governments, and will remain closed during Ramadan. 

Evening prayers during the month of Ramadan, which starts April 23, will be cancelled. Muslims will be asked to pray at home instead, said Abdul Hai Patel, the council’s director of inter-faith relations.

Not having the community aspect of Ramadan this year “is going to be challenging,” said Cindy Jadayel, a member of Ottawa’s Masjid ar-Rahmah or Mosque of Mercy.

“We have to work harder this year to have families happier in the home because we can’t go out and celebrate with others.”

“With the pandemic this year, it seems different,” said Riyaz Khawaja, president of the Hussaini Association of Calgary, the main Shia Islamic organization in the city.

“Congregation prayers and eating together, that part we’ll be missing, but it’s going to be better to observe ourselves and be more spiritual in these hard times,” he said.

Khawaja says people will still be live-streaming prayers and sermons, donating to food banks, checking on neighbours and making financial donations during Ramadan and looking to help wherever it’s needed.

He says Ramadan has always been about reflecting on those less fortunate.

Can you sterilize a cloth mask by ironing it?

We’re still receiving lots of questions about masks, including this one from Janet S., who is wondering whether ironing her homemade mask will be enough to sterilize it. 

The short answer is no. Ironing your cloth mask will not work.

McGeer says that you can destroy some of the virus by heating it up, but it’s not enough to effectively sterilize the mask. 

“Sterilizing requires a certain time, usually at least 10 minutes above a certain temperature like 65-70 degrees Centigrade, which you can’t get from ironing,” she says. 

Instead, Health Canada recommends laundering it on a hot cycle and drying thoroughly. 

“When you wash it, just the soap and water in the washing machine will remove the COVID-19,” says McGeer.

But what about other masks, such as disposable paper surgical masks, and coveted N95 masks, which are used in both health-care and construction settings?

Disposable masks are not designed to be reused, and N95 masks also have a limited shelf life. 

That said, PPE shortages are forcing some health care facilities to experiment with safely decontaminating and reusing disposable masks. For instance, some hospitals are using UV light and pressurized sterilization machines called autoclaves to clean masks, but these methods cannot be safely replicated at home. 

With the warmer weather arriving, will wearing open-toed shoes be an issue? 

As the weather warms up, people like Eydie are wondering whether open-toed shoes could be an issue in terms of transmitting COVID-19. 

Open-toed shoes are okay, according to Dr. Lynora Saxinger, an infectious disease physician at the University of Alberta.

“Even if you had possibly an infectious virus on a shoe, in order to be infected you’d have to handle the shoe and then touch your face, nose or mouth or inhale the virus from the shoe,” she says.

We’ve also received a number of questions about whether the virus can persist on footwear or on the ground. 

Dr. Peter Lin, a CBC News medical contributor and family physician, says while there is a small risk of the virus ending up on shoes from surfaces at grocery stores or other shops, the risk of contracting COVID off your shoes is low.

“The virus needs to get to your lungs, so [it’s] very low risk that you will get the virus into your lungs [from your shoes]. When you get home don’t walk around your place with your outside shoes, just leave them on a mat by the door.  No need to scrub down. Over a few days the virus breaks down on its own,” he says. 

So while the risk transmitting COVID-19 from your shoes to you is low, you can minimize it altogether by keeping a shoe-free household for now.

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.”
