At his daily update Thursday, Legault explained the concept of "natural immunity," arguing that gradual deconfinement is necessary in Quebec for people less at risk to develop antibodies.\nThe government is releasing its plan for the slow reopening of schools and businesses next week.\nVisit MTLBlog for more headlines.\nAt his COVID-19 press update on Thursday, François Legault explained introduced the concept of natural immunity to the novel coronavirus. Gradual deconfinement in Quebec, he explained, would allow "people who are less at risk" to "develop antibodies and be able to become immune." If "everyone stays at home, there's no one else among the immunized people."\n"We currently have a virus which is very powerful and the multiplication factor is between two and four," he said.\n"If one person infects two people, both people infect four, eight, 16, 32, 64. This is called exponential growth, it goes very quickly."\nShould half the population become immune, however, the multiplication factor is diminished.\n"Instead of having one, two, four, eight, 16, we're going to have one, one, one, one, one. So you see, the situation is much more under control if we manage to have a part of the population that is immune," said Legault.\nBy contrast, "if everyone stays home, [...] we find ourselves in a situation where we have to wait for the vaccine, which will arrive in maybe a year, maybe two years. We cannot ask people to stay home for two years."\nAn extended period of confinement could also lead to a second outbreak.\n"The worst thing to do would be to say to people: You all go out at the same time, in September or fall," he explained. "We could imagine, at that time, a wave that would be larger than the wave we have known for a month."\nHe said gradual deconfinement is "desirable for the health of our society."\nView this post on Instagram Notre priorité reste de trouver du personnel pour l’ensemble du réseau de la santé. Mon message aux gens qui peuvent aider est simple : on a besoin de vous. C’est pour ça qu’on a annoncé la prolongation du programme de primes aux travailleurs de la santé jusqu’au 31 mai. On a aussi l’équipement médical qu’il faut pour bien protéger le personnel. J’en profite pour remercier les entreprises d’ici qui travaillent fort pour fabriquer des blouses médicales. Concernant notre plan de réouverture, je précise qu’on va annoncer le calendrier la semaine prochaine, mais qu’on ne rouvrira rien la semaine prochaine. La réouverture va être graduelle et va seulement se faire avec l’accord de la Santé publique. 👉🏻 Glisse la photo à gauche A post shared by François Legault (@francoislegault.pm) on Apr 23, 2020 at 1:17pm PDT\nThe government is already preparing its plan for the reopening of schools and some businesses.\nWhile there won't be anything opening any time soon, the government will present a gradual deconfinement calendar next week.\nREAD ALSO: Dr. Arruda Said We Could 'Still Be Talking About Coronavirus' In 2021 'Or Even Until 2022'\n"We will not open anything until we have the OK of Dr. Arruda and his team. So I just want to be very clear there," stressed Legault.\nAccording to Dr. Arruda, the virus could continue to reappear until a vaccine is widely available. While he's famously wary of projections, he estimated Wednesday the virus could be around until 2022.\nView this post on Instagram Si la situation reste stable dans les prochains jours, la semaine prochaine on devrait pouvoir annoncer notre plan de réouverture graduelle des écoles. Je peux tout de suite vous dire que les semaines restantes du calendrier scolaire ne seront pas obligatoires. Les parents qui ne vont pas vouloir envoyer leurs enfants à l’école, pour toutes sortes de raisons, ne seront pas forcés de le faire. On avance. On va s’en sortir ensemble. 👉🏻 Glisse la photo à gauche A post shared by François Legault (@francoislegault.pm) on Apr 22, 2020 at 1:45pm PDT\n"People who are less at risk, people under 60 years old, [...] there may be natural immunity that will prevent a wave. Then, the reason, once again, why we want to avoid the wave, is to avoid losing control in the health network," explained Legault.\n#COVID19 - Au Québec, en date du 23 avril 2020 à 13 h, la situation est la suivante :21 838 cas confirmés158 995 analyses négatives (cas infirmés)1 411 personnes hospitalisées1 243 décèsPour en savoir plus sur la situation au Québec : https://t.co/fiqW5E4y8R— Santé Québec (@sante_qc) April 23, 2020\n"We must continue all of our efforts, we must stay united, that's how we will get through this together."\nStay tuned for more news.
