Software engineer says problems persist with ABTraceTogether app

  Software engineer says problems persist with ABTraceTogether app Problems persist with the Alberta COVID-19 contact tracing application, says a local software engineer whose assessment shows its failure to record exposures between iPhones. Mathieu Fenniak, a Calgary-based software developer who has experience creating apps for Apple products, tested the ABTraceTogether app recently. He concluded it does not effectively record potential exposures between iPhones and is inconsistent between Android and iPhone users. “Two iPhones with the ABTraceTogether app running in the background next to each other for over a day showed no record of being exposed to each other,” Fenniak explained.

Masks will again be available at A&W, Tim Hortons and McDonald’s Canada locations, among other organizations and services. Alberta ’s chief medical officer of health updates her stance on wearing masks in public to avoid the transmission of COVID - 19 .

Salt that crystallizes with sharp edges is the killer ingredient in the development of a reusable mask because any COVID-19 droplets that land on it would be quickly destroyed, says a researcher who is being recognized for her innovation.

Ilaria Rubino, a recent PhD graduate from the department of chemical and materials engineering at the University of Alberta, said a mostly salt and water solution that coats the first or middle layer of the mask would dissolve droplets before they can penetrate the face covering.

As the liquid from the droplets evaporates, the salt crystals grow back as spiky weapons, damaging the bacteria or virus within five minutes, Rubino said.

It found that mask mandates led to a slowdown in daily COVID - 19 growth rate, which became more apparent over time. The first five days after a mandate In one simulation, researchers predicted that 80 percent of the population wearing masks would do more to reduce COVID - 19 spread than a strict

Instead, COVID - 19 is most likely transmitted via droplets, which are often spread on surfaces and people's hands. The incorrect belief that masks are effective at preventing infection has caused several experts to raise their concerns, including the U.S. Surgeon General Jerome Adams, MD, who

"We know that after the pathogens are collected in the mask, they can survive. Our goal was to develop a technology that is able to inactivate the pathogens upon contact so that we can make the mask as effective as possible."

Rubino, who collaborated with a researcher at Georgia State University in Atlanta to advance the project she started five years ago, was recognized Tuesday with an innovation award from Mitacs. The Canadian not-for-profit organization receives funding from the federal government, most provinces and Yukon to honour researchers from academic institutions.

The reusable, non-washable mask is made of a type of polypropylene, a plastic used in surgical masks, and could be safely worn and handled multiple times without being decontaminated, Rubino said.

Alberta reveals its COVID-19 app has been used to trace only 20 cases over 6 months

  Alberta reveals its COVID-19 app has been used to trace only 20 cases over 6 months Alberta's COVID-19 tracing app — which launched in May and has been downloaded more than 260,000 times — has been used in "approximately 20 cases" to track down contacts of someone who tested positive for the disease, the provincial government has revealed. Ongoing concerns over the app, in a province that has opted out of a similar app offered by the federal government, come as Alberta sets new records for daily cases (more than 1,000 on Saturday), hospitalizations (264 at last count) and deaths (20 more reported Monday).

A new approach to testing for coronavirus ( COVID 19 ) is to be trialled by researchers here at the University of Leicester, which could determine whether a

It's been a bad couple of weeks for COVID - 19 in Alberta . Edmonton Mayor Don Iveson, Alberta Premier Jason Kenney, Education Minister Adriana LaGrange, and Calgary Mayor Naheed Nenshi have differing points of view on how best to respond to the latest surges in COVID - 19 cases in the province.

The idea is to replace surgical masks often worn by health-care workers who must dispose of them in a few hours, she said, adding the technology could potentially be used for N-95 respirators.

The salt-coated mask is expected to be available commercially next year after regulatory approval. It could also be used to stop the spread of other infectious illnesses, such as influenza, Rubino said.

Dr. Catherine Clase, an epidemiologist and associate professor of medicine at McMaster University in Hamilton, said the "exciting" technology would have multiple benefits.

Clase, who is a member of the Centre of Excellence in Protective Equipment and Materials in the engineering department at McMaster, said there wasn't much research in personal protective equipment when Rubino began her work.

"It's going to decrease the footprint for making and distributing and then disposing of every mask," she said, adding that the mask could also address any supply issues.

Governments across the country are starting to make mask wearing mandatory in certain situations to curb the spread of COVID - 19 . Here’s a closer look at why some advocates are calling for that to be more widespread, and why others have reservations.

As COVID - 19 cases increase sharply nationwide, some health experts are now recommending that seemingly healthy members of the public wear cloth masks when they’re out and about. On April 3, President Trump announced a new federal recommendation urging the public to wear cloth masks to

The Public Health Agency of Canada recently recommended homemade masks consist of at least three layers, with a middle, removable layer constructed from a non-woven, washable polypropylene fabric to improve filtration.

Conor Ruzycki, an aerosol scientist in the University of Alberta's mechanical engineering department, said Rubino's innovation adds to more recent research on masks as COVID-19 cases rise and shortages of face coverings in the health-care system could again become a problem.

Ruzycki, who works in a lab to evaluate infiltration efficiencies of different materials for masks and respirators, is also a member of a physician-led Alberta group Masks4Canada, which is calling for stricter pandemic measures, including a provincewide policy on mandatory masks.
