More than three years after the start of the COVID-19 pandemic, the World Health Organization (WHO) announced the end of the public health emergency of international concern on Friday. A “sigh of relief” which does not surprise the experts consulted by The Press.
“Everyone can breathe a big sigh of relief, it’s still a very good announcement,” reacted virologist Benoit Barbeau, professor in the department of biological sciences at the University of Quebec in Montreal (UQAM).
“I am not surprised, it was expected,” said Alain Lamarre, professor and researcher specializing in immunology, virology and cancer at the National Institute for Scientific Research.
“I think it’s a logical development,” also indicated André Veillette, researcher at the Montreal Clinical Research Institute (IRCM) and professor in the Department of Medicine at the University of Montreal.
The end of a chapter
“It is with great hope that I declare the end of the global health emergency,” WHO Director General Tedros Adhanom Ghebreyesus announced at a press conference in Geneva on Friday.
Mr. Ghebreyesus thus closed the chapter he himself had opened by declaring, on January 30, 2020, the highest level of health alert in international law.
“For Mr. and Mrs. Everyone, it will not change much since there are practically no measures limiting their daily lives that are still in place. It’s more in terms of monitoring,” notes Mr. Lamarre.
The end of the WHO alert does not mean that COVID-19 is gone. The coronavirus has continued to kill an average of five Quebecers per day since the start of 2023. And there are still 1,027 patients hospitalized with COVID-19, including 18 in intensive care. Nearly half (47%) of COVID admissions recorded over the past two weeks are mainly due to infection, according to data from the National Institute of Public Health of Quebec.
However, with the return of mild weather, the spread of the coronavirus seems to be slowing down significantly. The signal of COVID-19 in sewage from the province’s four main cities has been dropping sharply since the beginning of April, after remaining high all winter.
Canada’s Minister of Health, Jean-Yves Duclos, stressed in a press briefing that COVID-19 was still causing deaths and hospitalizations in the country, although in fewer numbers than before.
“There are the effects of the long COVID that are both little known yet and very significant,” he added from Ottawa.
One year after sub-variants
“We really see that there is a much more optimistic horizon compared to such a date in 2022, and before,” underlines Mr. Barbeau.

“While we could expect an increase in the winter, perhaps even in the fall [2022], we were relatively spared or, at least, it was maintained, both internationally and in Canada or Quebec. »
Barely a year ago, on May 4, 2022, the DG of WHO expressed concern about Omicron BA.4 and BA.5 subvariants, responsible for an “increase in the number of reported cases in the Americas and Africa”. The mutations kept the health systems on their toes, and did not seem to want to give them any respite. So what happened?
“The virus evolved in a classic direction: greater transmissibility, but much less virulence. And population immunity ensures that the virus no longer finds hosts who have never seen the virus or who have never been vaccinated,” explains Lamarre.
“In 2022, what really helped was that we had a vaccination which was still maintained, but also a number of Quebecers infected with the virus, so that we ended up with a hybrid immunity,” confirms Mr. Barbeau.
“It has been a key element in our ability to reduce the risk of infection with severe symptoms in the general population”, he says, also citing “a little better adapted” vaccines, the development of antivirals and better transmission support.
“COVID-19 has left, and continues to leave, deep scars”, however recalled the DG of WHO, speaking of the millions of people “who continue to experience the debilitating effects of post-COVID-19 conditions”. .
“I will not hesitate to call another meeting of the emergency committee if COVID-19 puts our world at risk again,” he warned on Friday.
“It is prudent to keep an emergency door, but the chances of that happening are low,” said Mr. Lamarre.
It’s more time for balance sheets.
“Loss of life was avoidable”, underlined Tedros Adhanom Ghebreyesus in Geneva, denouncing “a lack of coordination, equity and solidarity” which have harmed the fight against the pandemic.
“The good news is that all the efforts we have made have not been in vain,” notes Mr. Barbeau, recalling the development of vaccines “in record time” and certain effective antivirals.
“And with the shortcomings we have experienced, we know where to act to be better prepared for what could happen to us – in the most distant possible horizon, but which must still be considered as a possibility. »
