SARS-CoV-2 (Covid-19) Infection Process Video of scientific popularization. Animation. In this animation, a process in which a multitude of actors intervene (Enzymes, polysaccharides, cell organelles ...) is exposed, in a very simplified way. It is not a scientific video, but an outreach video that tries to explain, in the simplest possible way, a very complex process. I hope you like it. Guillermo Corrales Morales Music: Carlos Estella
What happens if a SARS-CoV-2 coronavirus enters your lung? This molecular animation visualises how the virus particle can take over the host cell and turns it into a virus factory. Eventually, the host cell produces so many viral particles that it dies, and releases numerous new virus particles. 🤍 Chapters: 00:00 Healthy respiratory cells 00:25 Components of the virus 01:06 Variants 01:31 Entering the host cell 02:15 Making viral proteins 03:00 Viral RNA knot 03:55 Double membrane vesicles 04:14 Replicating viral genome 04:48 Making more viral proteins 05:09 Creating new viral particles 05:49 Release from the cell Correction: 01:24 This should be D614G

How long can a virus keep attacking me - especially when I've been previously infected? How long do my antibodies survive in my blood? How long does a vaccine defend my immune system against an intruder? Scientists are grappling with these questions. And they have yet to find out for certain, how long vaccine protection lasts.

The COVID-19 omicron variant has been reported in nearly half of the U.S. states since it was first detected in California on Dec. 1. The second known case of omicron in the country was identified in Minnesota. "People that detect omicron — states, counties, countries — that doesn't necessarily mean that they were the first to have it," says Dr. Bobbi Pritt, director of Mayo Clinic's Division of Clinical Microbiology. "It is just that they were one of the first to detect it. In Minnesota, we were one of the first states to detect the presence of the omicron variant. And that's because we sequence a large number of our COVID-19 positive specimens. We have a very good sequencing system in place." Mayo Clinic Laboratories has been working with Minnesota state health officials and other academic medical centers looking for new variants by analyzing the virus's genetic code. For more, watch Dr. Bobbi Pritt talk about genome sequencing COVID-19 variants. For the safety of its patients, staff and visitors, Mayo Clinic has strict masking policies in place. Anyone shown without a mask was recorded prior to COVID-19 or recorded in an area not designated for patient care, where social distancing and other safety protocols were followed.

Lapses in strategies to tackle COVID-19 could create "the perfect conditions" for a deadly new variant to emerge, the World Health Organization's Director-General Tedros Adhanom Ghebreyesus warned on Friday. About 90 per cent of the world's population now has some level of immunity to SARS-COV-2 either due to prior infection or vaccination, according to the global health agency's estimates. "We are much closer to being able to say that the emergency phase of the pandemic is over, but we're not there yet," Tedros told reporters during a press conference. His comments come as China experiences a rebound in infections. The further easing of COVID-19 testing requirements and quarantine rules in some Chinese cities was met with a mix of relief and worry on Friday, as hundreds of millions await an expected shift in national virus policies after widespread social unrest. WHO's emergencies director Mike Ryan said he hopes that a coherent and clear strategy emerges in China "that balances the control of the virus with...the livelihoods, wellbeing and human rights of the people."

The Technical Advisory Group on SARS-CoV-2 Virus Evolution met today to review what is known about the #COVID19 variant B.1.1.529. They advised WHO that it should be designated a Variant of Concern. WHO has named it Omicron, in line with naming protocols Learn more: 🤍
Tutoriel vidéo Autotest Covid-19 L‘autotest, une nouvelle manière de dépister le coronavirus Attention: un autre test est un test nasale à réaliser soi même et ces tests sont destinés à des personnes de plus de 15 ans qui n'ont pas de symptômes et qui ne sont pas personnes contacts. L'idée étant de le répéter de manière régulière une à deux fois par semaine, pour avoir le plus de chance possible de détecter le virus . si le test est négatif, bien évidemment, il ne faut pas abandonner les gestes barrière. En cas de test positif, il faut absolument s'isoler et faire faire un test PCR en laboratoire pour confirmer le diagnostic.
Une étude sino-australienne a permis de découvrir de nouveaux virus chez des chauves-souris chinoises, dont cinq sont potentiellement dangereux pour l'Homme à cause d'une possible transmission. Cette découverte pourrait en outre permettre d'en apprendre plus sur l'origine du Covid-19, puisqu'un virus découvert est très proche au SARS-CoV-2.

While parts of the medical community are on the hunt for a vaccine against the coronavirus, others are on the hunt for its origin. While the first confirmed case was in China, the exact steps of the virus's early progression are still unknown. The current working theory is that virus originated in Wuhan, but there's still more to learn. Sequencing the virus' genome is key for the ongoing medical forensic investigation and scientists hope by pinpointing where the virus came from and how it jumped to humans they'll be able to develop the tools to fight the future evolution of COVID-19. It's a bit like a medical detective story. Following the clues should eventually lead us to the origin of the coronavirus that has brought us a year the world will never forget. To get to the beginning, we'll have to work backwards.Medical forensics is a big part of the equation now. Dozens of people connected to a wet market reported flu like symptoms in the early part of last December. The leading theory is that a man originally contracted the virus from a bat. The WHO is currently working to trace the virus' path to better understand how the pandemic could continue to spread.

“SARS-CoV-2 could always pick up a mutation that could just change the game,” Pardis Sabeti, a Harvard computational geneticist explains in this video exploring the basics of how viruses evolve as they infect more people. Sabeti and others use math and genetics to monitor new variants and provide insight into viral origins and spread. “One of the things that a lot of people feel complacent about is that [Covid-19] seems to affect people that are mostly elderly … or, you know, mostly not them,” she says. “But at any point this virus could change and affect them. It can become more lethal. It could become more lethal to our children. It can evade our vaccines. And so it’s one of those things where you just don’t want to give it a minute to change in a way that’s particularly bad.” It’s clear, she says, that “the best thing we can do is to get the infection rates to zero so that the virus has no opportunities to mutate and change.” READ MORE: Know thine enemy: Why genetic sequencing is key to tracking Covid-19 🤍 Reset: The Science of Crisis & Recovery 🤍 Annual Review of Virology Genomic Analysis of Viral Outbreaks 🤍 WATCH MORE FROM KNOWABLE MAGAZINE AND SUBSCRIBE: 🤍
