Dealing with the Fallout: Office of Chief Science Advisor of Canada

"The ongoing risk of infection and subsequent acute and chronic illness is not negligible. The SARS-CoV-2 virus continues to circulate with evolving variants of concern .... with each SARS-CoV-2 reinfection, the risk of developing [Long Covid] is cumulative. That means two infections carry a greater risk than one infection and the risk after three infections is larger than after two infections. As of June 20234, two out of three Canadians had at least on COVID-19 infection and one in five Canadians had been infected multiple times."

Yes, We Continue Wearing Masks—Here’s Why: Common Questions Answered - WHN
Picture a typical family gathering today. Most people have moved on from masking: kids run around freely, aunts and uncles chat over snacks, and only a couple of family members still choose to wear well-fitted masks. Soon, the questions start rolling in: “Isn’t the pandemic over?” “Aren’t you done with masks yet?” “But you’re not … Continued

Acute and postacute sequelae associated with SARS-CoV-2 reinfection - Nature Medicine
Acute and postacute sequelae associated with SARS-CoV-2 reinfection - Nature Medicine
People who had a reinfection with COVID-19 faced a higher risk of dying from any cause compared to those who didn't get reinfected. The risk was more than twice as high. They also had a higher chance of being hospitalized and experiencing long-term health issues related to the virus. Specifically, they were 3 times more likely to be hospitalized and over twice as likely to experience lasting symptoms, like those from long COVID.

Natural course of post-COVID symptoms in adults and children - Scientific Reports
Natural course of post-COVID symptoms in adults and children - Scientific Reports
Post-COVID symptoms were reported in 59.7% of individuals at initial recovery—78.4% in adults and 34.6% in children. Common symptoms in adults included fatigue (52.1%), cough (39.3%), and shortness of breath (37.5%), while children had lower prevalence. Symptoms resolved within three months for 40% of adults and 70% of children, but 60% of long-term cases persisted beyond a year. Overall, 20.7% had symptoms lasting over a year.

Immune damage in Long Covid | Science
Immune damage in Long Covid | Science
Acute infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cause a respiratory illness that can be associated with systemic immune cell activation and inflammation, widespread multiorgan dysfunction, and thrombosis. Not everyone fully recovers from COVID-19, leading to Long Covid, the treatment of which is a major unmet clinical need (1). Long Covid can affect people of all ages, follows severe as well as mild disease, and involves multiple organs.

What is Long COVID?
What is Long COVID?

Long COVID is an everyone problem because everyone has blood vessels, a gut microbiome, ACE-2 receptors, T cells and a blood-brain barrier. I wanted to demystify the words so finally they become real, and a part of you.

Long COVID is simply what happens when someone does not recover from COVID. It’s not imaginary, and it’s not even particularly mysterious. It is complicated, because bodies are complicated, and the virus is doing strange, fascinating things, going through forbidden doorways, entering sacred chambers.

Long COVID is blood vessel damage, brain damage, organ damage, immune system damage, and mitochondrial damage. It is real, it is devastating, and it is happening to people every day. And it can happen to you, after any infection.

New Medical AI Tool Identifies More Cases of Long COVID From Patient Health Records | Mass General Brigham
Researchers from Mass General Brigham are leveraging artificial intelligence to help identify the signs of long COVID, track how different symptoms manifest over time, and eliminate alternative explanations for patients’ symptoms. The new approach suggests that 22.8% of the population experience the symptoms of long COVID, a figure that may paint a more realistic picture of the pandemic’s long-term toll.

Long-term Risk of Heart Attack, Stroke and Death Doubles with History of COVID-19 Infection
The study found that people with any type of COVID-19 infection were twice as likely to have a major cardiac event, such as heart attack, stroke or even death, for up to three years after diagnosis. Stanley Hazen, MD, PhD summarizes the findings of this Cleveland Clinic led trial and implications for practice and future research.

Strokes, heart attacks, sudden deaths: Does America understand the long-term risks of catching COVID?
Strokes, heart attacks, sudden deaths: Does America understand the long-term risks of catching COVID?

"A 35-year-old acquaintance drops dead from a hemorrhagic stroke. A friend in her 40s, and another in his 70s, experience recurrent spells of extreme dizziness, their hearts pounding in their chests when they stand. A 21-year-old student with no prior medical history is admitted to the ICU with heart failure, while a 48-year-old avid tennis player, previously healthy, suddenly suffers a heart attack. A relative is diagnosed with pericarditis, an inflammation of the protective sac surrounding the heart.

I can’t confirm the exact etiology of all these cases. But every one of the people I mentioned had a history of COVID either days or months beforehand–and all of them experienced only mild cases of infection at the time.

Is it possible, despite everything we know, that we still underestimate COVID’s reach and danger? It is not normal for me to know so many people with severe conditions. Not normal at all."

When people with COVID-19 started getting strokes and heart attacks, scientists began researching the connection. They soon realized that the virus was attacking not just the respiratory system, but the vascular system as well.

There’s a good reason why: this novel coronavirus attaches itself to the human body via receptors called ACE-2. “Those ACE-2 receptors are quite prevalent in a lot of places in the body, especially the endothelium layer of the arteries and veins,” says Dr. Swartz. “The virus can get in there and inflame the blood vessels.”

Researchers Aim to Pull Back the Curtain on Long COVID in Kids
“We have convincing evidence that COVID-19 is not just a mild, benign illness for children,” said Lawrence C. Kleinman, a professor of pediatrics and population health expert at Rutgers Robert Wood Johnson Medical School (RWJMS) and the study’s third co-author. “There are children who are clearly disabled by long COVID for long periods of time.”

"We need to tell people why it’s bad to get COVID repeatedly. Tell people why COVID can shorten one’s lifespan. I think most people who are alive today will face the reality that COVID is a contributing factor to their death. Do people know this?"

We’ve Hit Peak Denial. Here’s Why We Can’t Turn Away From Reality — Scientific American
COVID is a good case study for illustrating the “Collective Denial Playbook” that underpins our new normal reality. If the COVID situation is tracked and the public warned, things don’t feel normal. But if we don’t monitor or mention it, then things can feel “back to normal”—fine, even.

How the press manufactured consent for never-ending COVID reinfections
How the press manufactured consent for never-ending COVID reinfections
A little over two years ago, on November 16, 2021, CNBC reported on Dr. Fauci’s assessment of what successfully ‘living with the virus’ would look like: “Covid cases must fall below 10,000 a day for U.S. to get to 'degree of normality'”. He went on to say that truly getting the virus under control would probably mean no more than 3,300 cases a day- this would be a reasonable rate that wouldn’t create major disruptions to overall social functioning. He made this projection, notably, nearly a year after the initial vaccine rollout. As of December 18, 2023, the infectious disease modeler’s projection of new daily cases in the US? 964,184 new cases per day. This is, quite factually, not the ‘new normal’ anyone was promised.

Engineers Canada: Ventilation systems and building management in reducing airborne contaminants

The role of ventilation in removing exhaled airborne bio-aerosols and preventing cross infections has been extensively studied by multiple disciplines for decades and was looked at closely after the SARS outbreak in 2003. It has been shown that the SARS-CoV-2 virus (leading to the COVID-19 disease), and other similar pathogens, can spread through aerosolized particles and therefore airborne transmission of the virus must be addressed to curb its spread. The World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) have made explicit references to this concern.
