Ontario asymptomatic testing program finds 57 COVID cases so far in more than 4,500 tests to date in Toronto, Peel, York, Ottawa – Toronto Star

Published

Ontario’s asymptomatic COVID-19 school testing program has so far found 57 cases after more than 3,600 tests in hot spots in Toronto, York, Peel and Ottawa, the Star has learned.

Almost half of those COVID cases were at one Toronto school, Thorncliffe Park Public School, which closed earlier this month after 26 were uncovered through the voluntary testing introduced by the government late last month.

The province is awaiting results on an additional 890 swabs, for a total of 4,544 tests conducted.

That means that so far, the positivity rate is less than two per cent, said a government source.

“It underscores what doctors have said all along: students aren’t getting COVID-19 in schools, they bring it into schools from the community,” said the source.

“Put this into perspective — in the highest-risk regions, with the highest rates of positivity, we have not seen asymptomatic spread.”

The province plans to expand the program, a first in the country, in the new year, as opposition critics continue to push for much more widespread testing in schools.

New Democrat MPP Marit Stiles, her party’s education critic and a former Toronto school board trustee, said until there is mass testing, “we are not going to have a handle on what we are dealing with.”

Amid rising cases in the community, the government sent a memo to boards advising them to prepare for online learning in case a quick switchover is needed.

Stiles, however, said the government needs to do more.

“Open or closed is not a plan,” she said. “Kids will be back at school” at some point, and the government needs to decrease class sizes, among other things, to allay families’ fears.

“The parents I have spoken to are very worried and upset about it,” she said.

Green party Leader Mike Schreiner urged Premier Doug Ford to “make the call now for an extended winter break for schools, so parents and educators can plan. And provide supports for parents who need to take time off or find child-care options during that time. Use the extended break to improve ventilation in schools and to reduce class sizes to ensure safe physical distancing when students return to school.”

At a press conference Thursday, Ford was asked about further lockdown measures, including the possibility of remote learning for students after the holiday break.

“Everything is on the table,” he said. “And if we do move forward and decide to do a further lockdown there are a lot of things to take into consideration. There’s the education, making sure that we have daycare, making sure the educators are ready … having hotels for people that have COVID, that we can put them into hotels instead of at home. We have to make sure that we have something for the businesses.”

Ford also said Education Minister Stephen Lecce “has put the schools on notice as well. So it’s all hands on deck. We have to be ready for anything. And the trend is moving at a rapid, rapid fashion right now. So we’re going to be ready.”

As of Thursday, Ontario reported an additional 170 COVID cases among students and staff in all public schools, for a total of just over 7,000 since classes began in September. Some 955 schools, out of the province’s 4,828 have reported cases, or roughly one in five.

Meanwhile, a new memo to Toronto District School Board principals and vice-principals has raised concerns about reporting of cases and transparency over the holidays.

It says that “during the winter break, schools are NOT required to report cases to (the board’s) Occupational Health and Safety or the Ministry’s Go Secure website. Reporting of positive cases will resume as per the TDSB COVID-19 Response Plan on Monday, January 4.”

The memo, obtained by the Star, said that “in line with the Ministry of Education, the TDSB COVID-19 Advisories website will NOT be updated during the winter break, however any recommendation from (Toronto Public Health) for staff and/or students to self isolate will continue to be communicated to directly-impacted classes only.”

Whooping cough is at a decade-high level in US

Published

 on

 

MILWAUKEE (AP) — Whooping cough is at its highest level in a decade for this time of year, U.S. health officials reported Thursday.

There have been 18,506 cases of whooping cough reported so far, the Centers for Disease Control and Prevention said. That’s the most at this point in the year since 2014, when cases topped 21,800.

The increase is not unexpected — whooping cough peaks every three to five years, health experts said. And the numbers indicate a return to levels before the coronavirus pandemic, when whooping cough and other contagious illnesses plummeted.

Still, the tally has some state health officials concerned, including those in Wisconsin, where there have been about 1,000 cases so far this year, compared to a total of 51 last year.

Nationwide, CDC has reported that kindergarten vaccination rates dipped last year and vaccine exemptions are at an all-time high. Thursday, it released state figures, showing that about 86% of kindergartners in Wisconsin got the whooping cough vaccine, compared to more than 92% nationally.

Whooping cough, also called pertussis, usually starts out like a cold, with a runny nose and other common symptoms, before turning into a prolonged cough. It is treated with antibiotics. Whooping cough used to be very common until a vaccine was introduced in the 1950s, which is now part of routine childhood vaccinations. It is in a shot along with tetanus and diphtheria vaccines. The combo shot is recommended for adults every 10 years.

“They used to call it the 100-day cough because it literally lasts for 100 days,” said Joyce Knestrick, a family nurse practitioner in Wheeling, West Virginia.

Whooping cough is usually seen mostly in infants and young children, who can develop serious complications. That’s why the vaccine is recommended during pregnancy, to pass along protection to the newborn, and for those who spend a lot of time with infants.

But public health workers say outbreaks this year are hitting older kids and teens. In Pennsylvania, most outbreaks have been in middle school, high school and college settings, an official said. Nearly all the cases in Douglas County, Nebraska, are schoolkids and teens, said Justin Frederick, deputy director of the health department.

That includes his own teenage daughter.

“It’s a horrible disease. She still wakes up — after being treated with her antibiotics — in a panic because she’s coughing so much she can’t breathe,” he said.

It’s important to get tested and treated with antibiotics early, said Dr. Kris Bryant, who specializes in pediatric infectious diseases at Norton Children’s in Louisville, Kentucky. People exposed to the bacteria can also take antibiotics to stop the spread.

“Pertussis is worth preventing,” Bryant said. “The good news is that we have safe and effective vaccines.”

Scientists show how sperm and egg come together like a key in a lock

Published

 on

 

How a sperm and egg fuse together has long been a mystery.

New research by scientists in Austria provides tantalizing clues, showing fertilization works like a lock and key across the animal kingdom, from fish to people.

“We discovered this mechanism that’s really fundamental across all vertebrates as far as we can tell,” said co-author Andrea Pauli at the Research Institute of Molecular Pathology in Vienna.

The team found that three proteins on the sperm join to form a sort of key that unlocks the egg, allowing the sperm to attach. Their findings, drawn from studies in zebrafish, mice, and human cells, show how this process has persisted over millions of years of evolution. Results were published Thursday in the journal Cell.

Scientists had previously known about two proteins, one on the surface of the sperm and another on the egg’s membrane. Working with international collaborators, Pauli’s lab used Google DeepMind’s artificial intelligence tool AlphaFold — whose developers were awarded a Nobel Prize earlier this month — to help them identify a new protein that allows the first molecular connection between sperm and egg. They also demonstrated how it functions in living things.

It wasn’t previously known how the proteins “worked together as a team in order to allow sperm and egg to recognize each other,” Pauli said.

Scientists still don’t know how the sperm actually gets inside the egg after it attaches and hope to delve into that next.

Eventually, Pauli said, such work could help other scientists understand infertility better or develop new birth control methods.

The work provides targets for the development of male contraceptives in particular, said David Greenstein, a genetics and cell biology expert at the University of Minnesota who was not involved in the study.

The latest study “also underscores the importance of this year’s Nobel Prize in chemistry,” he said in an email.

Older patients, non-English speakers more likely to be harmed in hospital: report

Published

 on

 

Patients who are older, don’t speak English, and don’t have a high school education are more likely to experience harm during a hospital stay in Canada, according to new research.

The Canadian Institute for Health Information measured preventableharmful events from 2023 to 2024, such as bed sores and medication errors,experienced by patients who received acute care in hospital.

The research published Thursday shows patients who don’t speak English or French are 30 per cent more likely to experience harm. Patients without a high school education are 20 per cent more likely to endure harm compared to those with higher education levels.

The report also found that patients 85 and older are five times more likely to experience harm during a hospital stay compared to those under 20.

“The goal of this report is to get folks thinking about equity as being a key dimension of the patient safety effort within a hospital,” says Dana Riley, an author of the report and a program lead on CIHI’s population health team.

When a health-care provider and a patient don’t speak the same language, that can result in the administration of a wrong test or procedure, research shows. Similarly, Riley says a lower level of education is associated with a lower level of health literacy, which can result in increased vulnerability to communication errors.

“It’s fairly costly to the patient and it’s costly to the system,” says Riley, noting the average hospital stay for a patient who experiences harm is four times more expensive than the cost of a hospital stay without a harmful event – $42,558 compared to $9,072.

“I think there are a variety of different reasons why we might start to think about patient safety, think about equity, as key interconnected dimensions of health-care quality,” says Riley.

The analysis doesn’t include data on racialized patients because Riley says pan-Canadian data was not available for their research. Data from Quebec and some mental health patients was also excluded due to differences in data collection.

Efforts to reduce patient injuries at one Ontario hospital network appears to have resulted in less harm. Patient falls at Mackenzie Health causing injury are down 40 per cent, pressure injuries have decreased 51 per cent, and central line-associated bloodstream infections, such as IV therapy, have been reduced 34 per cent.

The hospital created a “zero harm” plan in 2019 to reduce errors after a hospital survey revealed low safety scores. They integrated principles used in aviation and nuclear industries, which prioritize safety in complex high-risk environments.

“The premise is first driven by a cultural shift where people feel comfortable actually calling out these events,” says Mackenzie Health President and Chief Executive Officer Altaf Stationwala.

They introduced harm reduction training and daily meetings to discuss risks in the hospital. Mackenzie partnered with virtual interpreters that speak 240 languages and understand medical jargon. Geriatric care nurses serve the nearly 70 per cent of patients over the age of 75, and staff are encouraged to communicate as frequently as possible, and in plain language, says Stationwala.

“What we do in health care is we take control away from patients and families, and what we know is we need to empower patients and families and that ultimately results in better health care.”
