"NEW FLU VIRUS MUTATION could see WORST SEASON in a DECADE"
Insights for understanding SARS-COV-2 (1st part) 🤔
Thanks to @mryoung151
for the article bbc.com/news/articles/…
2) Let's start with an overview of this article.
A newly mutated H3N2 influenza virus strain has emerged unexpectedly during summer, raising concerns about a potentially severe flu season, possibly the worst in a decade.
3) This strain's mutations, linked to an antigenic shift, enable it to evade existing immunity and increase its spread, with an estimated R of 1.4. Though the current flu vaccine may offer limited protection, health officials emphasize the importance of antiviral treatments and..
3)... to protect ourselves.
Why is it essential to understand the difference between antigenic shift and drift? What can this knowledge reveal about SARS-CoV-2, a single-stranded RNA virus rather than a segmented virus like influenza?
4) Additionally, how does this understanding shed light on the evolution of the pandemic?
We will address these questions in a second part. Stay tuned!

But WHO ARE ALL THESE DEAD PEOPLE that NO ONE is TALK ABOUT?
Imagine if every day in Europe, three or four planes carrying 180 passengers each were to crash, leaving no survivors, and yet no one talked about it. This troubling silence isn't just a European phenomenon;
2) it extends to many countries around the globe.
Looking back at the period from 2015 to 2019, the European community recorded about 5 million deaths each year—a figure that, while varying slightly depending on the sources, remained relatively stable.
3) However, during the three major pandemic waves from 2020 to 2023, the death toll surged, indicating a significant excess mortality (the difference between reported deaths and expected deaths).
The FUNNEL of ESCAPE : Unlocking the Secrets of SARS-CoV-2 Survival !
An explanation for Kids 👩❤️👨based on this recent study :
"Constrained Evolutionary Funnels Shape Viral Immune Escape" biorxiv.org/content/10.110…
2) In this study, scientists are trying to understand how tricky viruses, like the one that causes COVID-19, try to escape from our body's defenses.
**The Virus and Our Immune System:**
- Viruses are sneaky and always want to find new ways to avoid being caught ...
3) ... by our immune system (the body's defense system). Think of it like a character in a game that needs to avoid traps and heroes trying to catch them.
In the world of infectious diseases, panzoonotic diseases stand out for their ability to spread between multiple animal species and from animals to humans, revealing our interconnectedness.
What MAKES COVID-19 a UNIQUE PANZOONOTIC?
2)To grasp this, we must acknowledge the major panzoonotics that have influenced public health: Rabies (spanning 190 species) , COVID-19 (58 species), and avian influenza (48 species).
While COVID-19 is prominent, other diseases ...
3)... like Ebola or Zika illustrate this complex transmission. Bacterial panzoonotics, such as brucellosis or leptospirosis further emphasize the diverse threats we face.
What Are the KEY DIFFERENCES That Make SARS-CoV-2 UNIQUE Among RESPIRATORY VIRUSES Like INFLUENZA and RHINOVIRUSES?
▶️ TRANSMISSION MECHANISM :
- **SARS-CoV-2** primarily spreads through aerosols and contact with contaminated surfaces. It has a longer viral shedding period ...
2) ...which can lead to asymptomatic spread.
- **Influenza**: Also spreads via respiratory droplets, but typically has a shorter contagious period and less asymptomatic transmission compared to SARS-CoV-2.
3) - **Rhinoviruses**: Mainly spread through direct contact and respiratory droplets but are often more localized to the upper respiratory tract.
▶️ INFECTIOUS DOSE:
- **SARS-CoV-2**: Can be infectious with a lower viral load, which may contribute to its rapid spread.

The Long-Term Anxious Legacy of COVID-19 and potential impact on Millions of Kids
A recent study in Nature reveals that mice infected with SARS-CoV-2 exhibited changes in their sperm that led to increased anxiety levels in their offspring
