4) **Severity of Illness**: The virus can cause a wide range of symptoms, from mild to severe respiratory illness, and it has led to severe health complications in many cases.
5) **Mortality Rate**: While the mortality rate varies by demographic, it has resulted in millions of deaths worldwide, highlighting its dangerous nature.
6) **Vaccine Availability**: Although vaccines have been developed, the emergence of variants has raised concerns about their effectiveness and the need for booster doses.
7) **Treatment Options**: Treatment options are limited compared to other viral infections, and not all patients respond effectively to available therapies.
8) **Mutation Rate**: SARS-CoV-2 has shown a capacity for mutation, leading to new variants that can evade immune responses and potentially increase transmissibility or severity.
9) **Impact on Healthcare Systems**: The pandemic has overwhelmed healthcare systems globally, leading to increased morbidity and mortality due to resource strain.
10) **Societal Impact**: The virus has caused widespread economic disruptions, social isolation, and mental health issues, affecting communities on multiple levels.
11) **Long-term Effects**: Many survivors experience long-term health complications, known as "long COVID," which can significantly impact their quality of life.
13) ... which has been quite a challenge. On a personal note, it was also a wonderful opportunity to embrace life. If you have Instagram, you can catch a glimpse of our exciting adventure through some photos on @emmanuel.0862

"70% to 90% of our CELLS are completely RENEWED in less than 5 YEARS!
So If we’re mostly "New", why are so many still struggling with SARS-CoV-2?
We will tackle this question, which is more complex than it seems, in several posts.
2) First, let's say a few words about cell renewal.
70% to 90% of our cells are renewed over time. This turnover occurs in various cell types, including skin, blood, and immune cells, allowing the body to replace damaged or aged cells. sciencefocus.com/the-human-body…
3) For instance, red blood cells have a lifespan of about 120 days, while skin cells regenerate every few weeks.
Even with significant cell renewal, aging persists due to changes in our DNA. sciencefocus.com/the-human-body…
2) Co-infection occurs when a person is infected by more than one virus at the same time. This can lead to interesting and sometimes complex interactions between the viruses
3) In one study about SARS-CoV-2, researchers found that when different versions of this virus infect the same person, they can mix their genetic material through a process called recombination. This means that the new version of the virus can have traits from both parent viruses
For more than three years, we have been emphasizing that the envelope protein is an essential component and that we cannot limit our focus to just the spike protein. We are now uncovering its role in long COVID.
3) The Envelope (E) protein of SARS-CoV-2 plays a crucial role for several reasons:
▶️ Virus Assembly and Release: The E protein is essential for the virus's assembly and budding from infected cells, contributing to its stability and infectivity.
In 2022, COVID-19 was the second leading cause of death globally, with the repercussions of the virus far from over. The lasting impact of the pandemic continues to affect lives around the world.
Recent research may have identified a key factor contributing to long COVID: microscopic clots intertwined with immune system debris in the blood. These unusual structures were found to be nearly 20 times more prevalent ...
2) ...in long COVID patients compared to healthy individuals. The clots, associated with neutrophil extracellular traps (NETs), suggest a potential biological marker for persistent symptoms.
3) These microclots could impede blood flow in small vessels, leading to issues like brain fog, fatigue, and shortness of breath.
Unlocking the Secrets: A Comprehensive Megathread on Key Virus Subtypes of Human and Avian Influenza !"🧵
First, a quick overview of the different subtypes:
HUMAN INFLUENZA
H1N1 : The 2009 pandemic strain, which continues to circulate
...
2) H3N2: Strain spreading fast actually and causing significant morbidity
H6N1: Notable for potential human impact.
AVIAN INFLUENZA :
H5N1: High pathogenicity, zoonotic concerns.
H3N8: Emerging strain of interest.
H7N9: Associated with human infections, sporadic outbreaks.
3) H5N8: Emerging strain with health implications.
H5N6: Recent cases in birds and humans.
H7N7: Impact on poultry and occasional human cases.
H9N2: Common in birds, history of human infections.
