The city of Toronto is canceling its tactile search efforts as the city deals with a buildup of coronavirus infections. Cases are expanding so that touch search is no longer possible, experts say.
Although touch studies are effective in combating the spread of the virus, when instances begin to increase, it is difficult to implement them unless adequate resources are available.
“Deep down, (contact research) is sure to work,” said Alon Vaisman, a doctor of infectious diseases and infections at the University Health Network in Toronto. “But you want resources and do it fast. If you can’t do it in 24 to 40 hours, it becomes almost impossible. “
Seeking contact is a way to locate others who would possibly be contagious and keep them away from others. It can break the coronavirus chain of transmission and help you avoid epidemics. The World Health Organization has called it an “essential public aptitude tool for the virus. “
The concept is to look for the inflamed user before he infects others and prevent the “next generation of COVID-19 cases,” said Ashleigh Tuite, an epidemiologist at the University of Toronto.
“But you have to do it temporarily because the virus is spreading temporarily,” he said.
“It’s a virus race. “
And if fitness doesn’t have enough touch markers (people trained to call those who tested positive for COVID-19 and gather information), this can be a lost battle.
“Ultimately, it becomes staying awake,” he says.
That’s what happened in Toronto week.
On October 4, Toronto Public Health announced that it would reduce its tactile tracking efforts as the city fights a “high level” of infections. Instead, he said the city will focus its study efforts on high-risk scenarios, such as schools and long-term care homes.
“As a component of the same old outbreak control, when instances are successful at a higher level, public aptitude wants to make a strategic shift and temporarily redefine the precedence of touch and case control in the most risky scenarios,” said the Medical Officer of Toronto Health. Dra. Eileen de Villa.
He said there are 700 touch trackers in Toronto, the highest in the country, but infection rates are expanding so that they go beyond touch tracking, “no matter how many other people are deployed to do so.
“I think we may only have another 700 people added to the ranks and we still can’t locate contact with the same scope and effects when infections were lower,” he said, adding that he hopes Toronto will return to normal touch studies as soon as COVID-19 instances start streaming again.
Vaisman said Toronto’s resolve to trace the opposite touch “makes sense” given the city’s resources.
“In an ideal world, we would have enough tactile calls every day to answer all cases,” he said. “But the challenge is resources and money, it’s as undeniable as that. If you have the resources, locating contacts is very important. But if that’s not the case, I think it’s the right solution to move resources to other contexts, like vulnerable people. “
He added that by searching for contacts, “you do it right or you don’t do it at all. “
But there are more resources coming into Ontario, which can reduce the delay.
On Tuesday, Ontario Prime Minister Doug Ford said the province is investing $1. 3 billion in COVID-19 testing and tactile studies as a component of its fall readiness plan to reduce the province’s delays and testing capabilities.
During the first wave of the pandemic in March, touch tracking was used and worked well, Vaisman said.
But there’s a key difference between March and now, he said: in the spring, the average user was aging with the virus and the shops, restaurants and gyms were also closed, so other people couldn’t get out as much, he added.
In the wave at the moment, the average user inflamed by the virus is now sometimes younger and more socially mobile, Vaisman said, adding that shops, restaurants and gyms are also open, contributing to the spread.
So, if you touch one or two more people, you might want to touch another thousand people a day, and without the resources to do it in a timely manner, he said, the cases eventually spread.
Tuite said canadian Atlantic provinces, which have low CASES of COVID-19, have been able to effectively use touch tracking techniques.
For example, since 1 October, Nova Scotia has had a proven case of coronavirus, Ontario has reported more than 2,000 cases since the beginning of the month and Quebec has recorded more than 7,500 cases.
COVID-19 cases, as in Ontario and Quebec, are the touch markers you need.
“But we have a limited number of touch markers, and in the end we have to say “we can no longer go on” and we will have to prioritize and concentrate on long-term care centers or schools. Tuite said.
Vaisman said there’s a generation that can help, like Canada’s national tracking app, but there’s that.
The app does not paint in the classic touch search direction, but instead notifies other people about the proximity of a user who has informed the app of a positive coronavirus check result.
The application is also optional, as it is not mandatory for positivers to record this data to alert others to possible exposures. The generation has not yet been deployed in all provinces.
Finding contacts is the only challenge facing provinces like Ontario and Quebec.
There are also challenges with testing because it takes time to get a COVID-19 result: days. Another challenge is testing, as queues continue to grow at sites across the country.
Vaisman said that when these three problems are combined (difficulties in tracking contacts, long queues to test, and accumulating effects), foreclosure is “inevitable. “

“Not being able to look for touch means no one knows what’s going on. We have a rough idea, but no one really knows who was in touch with whom. If you don’t have the resources to track touches, all you can do is prevent everything. Quite a lock-up. “
Tuite agreed.
He said that if the contact search was not imaginable and the province had to reduce COVID-19 numbers, restricting contact is another option.
“That’s where we are now. There are too many cases and testing and tracking don’t work. So, we want to start over with the final bars and restaurants so that the boxes return to a manageable level,” he said.
On Friday, Ontario announced that it would implement restrictions in Toronto and Ottawa to help prevent the spread of the virus.
The new measures, which are expected to take effect on Saturday at 12:01 a. m. , come with the closure of indoor restaurants and bars, as well as the closure of gyms, casinos, cinemas and performing arts centers.
