The researchers emphasize that lifting lockdowns should occur progressively, reasonably than suddenly.
“We have to be very cautious right here,” mentioned Dr. Peter Juni, a professor of epidemiology and drugs on the College of Toronto, and the research’s lead creator. “In any other case we can have mass gatherings on faculty yards and in gyms et cetera, which might backfire huge time.”
The research, which seems on this week’s concern fo the Canadian Medical Association Journal, discovered that placing two restrictions in place directly — akin to closing faculties and asking folks to bodily distance themselves — diminished the expansion of recent COVID-19 instances by at the very least 30 per cent.

“Sadly for all of us, the climate will not come to our assist an excessive amount of right here,” Juni mentioned.
It is potential, nevertheless, that humidity performed a minor function in hindering the expansion of recent instances. But it surely paled compared to the results of distancing and stopping mass gatherings, the researchers mentioned.

“We should not be afraid of our fellow residents,” he mentioned. “The caseload is now low sufficient that we will begin to enterprise into the territory of opening up economies on the similar time not be so assured to be flagrant with our hygiene self-discipline.”
For the research researchers on the College of Toronto, Western College in London, Ont., and colleagues in Switzerland in contrast how nicely 144 international locations carried out in flattening their epidemic curves.
