Chinese scientists obtain genetic sequence of mysterious virus – STAT

Published

 on


Chinese scientists have recovered a previously unknown virus from an infected individual and generated a full genetic sequence of it, a key step in efforts to learn more about the cause of an outbreak of unusual pneumonia in the city of Wuhan, state-run media reported Thursday.

Fragments of the same virus were picked up in testing of 15 patients among the 59 who have been identified as infected with the mysterious pneumonia.

The speed of the findings is impressive; the first case in this outbreak became ill less than a month ago.

“Preliminary identification of a novel virus in a short period of time is a notable achievement and demonstrates China’s increased capacity to manage new outbreaks,” the World Health Organization’s representative in China, Dr. Gauden Galea, said in a statement.

But more work is needed to identify what animal species transmitted the virus to people and whether there are other cases elsewhere, Galea said.

The report on CCTV appears to be the first official confirmation from Chinese authorities that they believe a new virus is responsible for this outbreak — specifically a coronavirus, a type of virus in the family that includes SARS and MERS.

When viewed under an electron microscope, it exhibits the crown-like halo that gives coronaviruses their name, said Xu Jianguo, identified by CCTV as the leader of the preliminary assessment of the test results and a member of the Chinese Academy of Engineering.

The outbreak is occurring in Wuhan, about 700 miles south of Beijing. Wuhan is a leading center for virology research in China, and infectious diseases experts watching this outbreak have predicted scientists there would quickly find the cause.

“The virology team investigating this outbreak at Wuhan and China CDC are world class and they are making good progress on identifying the causative agent,” Malik Peiris, a microbiologist at the University of Hong Kong, told STAT.

Peiris was one of the scientists who first identified the coronavirus that caused the 2003 SARS outbreak, which infected more than 8,000 people and killed nearly 800 in China, Hong Kong, and several other Asian countries as well as in Toronto, Canada.

The first known case in the Wuhan outbreak became noticeably ill on Dec. 12, according to a statement released Sunday by the Wuhan Municipal Health Commission. The discovery of an outbreak and identification of a new virus in a period of less than one month is exceptional, experts said.

“I am stunned by the timeline and speed of this isolation and characterization, if it’s all true,” said Matthew Frieman, a coronavirus expert at the University of Maryland School of Medicine.

The community of scientists who research emerging infectious diseases has been speculating for days that the source of the outbreak was a new coronavirus, a class of viruses that has shown itself adept at making the leap from animals to people. Coronaviruses originate in bats but are able to infect a number of mammals.

Confirmation that scientists have the genetic sequence of the virus will increase pressure on China to release at least part of that sequence, so that health facilities around the world know what to look for as they try to detect possible cases from this outbreak.

In the United States, the Centers for Disease Control and Prevention on Wednesday instructed doctors to ask patients with severe respiratory infections whether they have been to Wuhan. Hong Kong and other countries in Southeast Asia are isolating any such cases until they can be tested for influenza, rhinoviruses, and other viruses that cause colds and flu.

This type of very broad net will draw in many people who were in or near Wuhan and who have a respiratory tract infection but who have nothing to do with this outbreak — especially in the middle of flu season. That will eat up resources and the time of doctors, laboratories, and sick people who don’t need to be isolated.

“If the Chinese truly have sequenced the virus and they’ve demonstrated that it’s present in other patients, that’s means there’s a PCR diagnostic test available. And the Chinese need to make that available to the rest of the world immediately,” said Ralph Baric, a coronavirus expert at the University of North Carolina.

“And the longer they wait, the more likely the scientific community will go from a positive response to a negative response, in terms of how China is handling this outbreak,” he said.

The CCTV report did not provide details on the type of coronavirus that has been discovered — for instance if it is one of several SARS-like viruses that have been found in bats in China. A number of these SARS-like viruses are able to infect human tissue cells in the laboratory, suggesting they might be able to spill over into people if given the right circumstances.

Xu said more research on the new virus is needed.

There has been limited information about the nature of the illness in people who have been infected. Chinese authorities have said no one has died from this infection; seven, however, were in critical condition as of Sunday. In a statement that same day, the WHO said that the main symptom was fever; some patients had difficulty breathing.

The CCTV report also did not indicate whether scientists investigating the outbreak had identified the source of the virus.

Baris said coronaviruses could jump to people directly from bats, which are eaten in China. But this virus could have used what is known as an intermediate host — an animal species that becomes infected with a bat virus that then transmits it to people.

During the SARS outbreak, it was determined that palm civets, a wild animal eaten as a delicacy in southern China, were transmitting the virus. Chinese authorities ordered a widespread culling of civets to help stop the outbreak.

The Wuhan outbreak has been linked to a large seafood market that also sells live exotic animals for consumption. The market was closed and decontaminated on Jan. 1. But it is important to know if other markets are selling infected animals, Peiris said.

“If it can jump once, then it will jump again,” he said of the virus.

The WHO said Wednesday that Chinese authorities believe the virus “does not transmit readily between people.”

Earlier statements from the Wuhan Municipal Health Authority said there has been no person-to-person spread, but disease experts challenged that claim, saying it is impossible to rule out at this stage in the exploration of a new disease.

“I don’t know how you know that at all,” Frieman said of China’s claim there is no person-to-person transmission. He noted the number of cases reported makes it seem unlikely that animal-to-human transmission is the only way this virus spread.

There have been at least one or two clusters of cases within families that have raised suspicions of limited person-to-person spread, a source familiar with the outbreak told STAT.

News of the pneumonia cases first emerged on Dec. 30, when the local health authority told hospitals to be on the lookout for cases. The next day Chinese authorities informed the WHO that they were dealing with what looked like an outbreak caused by an unknown virus.

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.”
