MONTREAL — Two weeks after Quebec imposed a partial lockdown on its two biggest cities, the number of new, daily COVID-19 infections reported by health authorities has stabilized.
The fact the daily case numbers haven't continued to rise is "justification for a little bit of restrained optimism," said Dr. Christopher Labos, a Montreal-based cardiologist with a degree in epidemiology.
He said the partial lockdown, which forced gyms, bars and other venues to close and banned indoor and outdoor gatherings, was the right move. Quebec imposed those restrictions on Montreal and Quebec City on Oct. 1, and recently announced the same for many other parts of the province.
"I really don't see that there's any other option," Labos, who has worked with McGill University's Office for Science and Society, said in an interview Wednesday.
Health officials reported 1,203 new cases Wednesday -- 844 of which were recorded during the previous 24 hours. The other 359 cases were confirmed between Oct. 10 and 12 but were previously unreported because of what the Health Department said was a "technical problem" during an update to a computer system.
Labos said it will take at least two weeks -- maybe more because of testing backlogs -- to evaluate the effect of the government's latest approach to slowing the spread of COVID-19.
But it's almost impossible, he explained, to determine what effect specific measures have had on the rate of COVID-19 infection. All of the restrictions imposed by the government worked in tandem, leaving scientists without the ability to conduct randomized trials, he said.
Anti-lockdown advocates have been rejoicing following a recent interview by British magazine The Spectator with the World Health Organization's special envoy on COVID-19, Dr. David Nabarro.
During the interview, which made headlines around the world, Nabarro said the WHO doesn't advocate for lockdowns as a primary means of controlling the virus.
Labos said he's worried those comments are being taken out of context.
At no point during that interview did Nabarro say lockdowns don't work, Labos said. Lockdowns wouldn't be necessary, Labos explained, if Quebec had an adequate contact tracing program and every positive case could be identified and isolated.
"A lockdown becomes necessary when you have uncontrolled explosive growth, which is unfortunately what we had," he said.
Roxane Borges Da Silva, a professor at Universite de Montreal's school of public health, said Quebec followed WHO recommendations by imposing targeted lockdowns. She said that approach was a good decision.
By keeping some services open -- such as retail businesses and manufacturing -- she said the government is trying to find a balance between protecting the health-care system and keeping people working. That equilibrium, she said, "is very hard to find."
The fact a computer issue reportedly delayed the reporting of some positive tests is "one more reason" it's too early to say whether the restrictions in Montreal and Quebec City have been effective, Borges Da Silva said.
Other data is also important, she said. "Hospitalizations are the most reliable indicator."
Health authorities Wednesday reported one death linked to the novel coronavirus in the past 24 hours and five COVID-19 deaths from earlier dates, for a total of 5,976. Hospitalizations increased by 20 to 488, with 80 patients in intensive care, a decrease of five.
Quebec has now reported a total of 88,994 COVID-19 cases.
On Wednesday afternoon, Parti Quebecois leader Paul St-Pierre Plamondon said his party wants the government to start sharing what advice it’s getting from public health officials.
"If we want to maintain trust between the public and the government, public health has to provide information," Plamondon told reporters. "We have to be able to know what the recommendations are and, ultimately, separate the politics from the science."
COVID-19 Resources Canada, a national group of researchers, has also called for the Quebec government to share more information about what advice it’s receiving from public health officials. The group says other provincial governments are more forthcoming with that kind of information.
