SARS-CoV-2 can INFECT HUMAN EMBRYOS
(mega-thread)

In this first study published end of 2022, they detected cases of infection that compromised embryo health. nature.com/articles/s4159…
Image
2) They identified "embryo cells express genes required for SARS-CoV-2 infection" Image
3) They evaluated the presence and localization of entry factors in trophectoderm cells
Image
Image
4) Some embryos readily displayed evidence of infection when exposed to the virus Image
5) In another study, under paywall 😡, they confirmed that "SARS-CoV-2 infection negatively impacts on the quality of embryos by delaying early embryonic development"

SARS-CoV-2 infection reduced the number of oocytes and high-quality embryos on day 3.onlinelibrary.wiley.com/doi/10.1111/aj…
6) We recall that the that VACCINATION PROTECTS PREGNANT women and NEONATES

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 ... Image
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. Image

SPERM, STRESS, and the NEXT GENERATION:
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 Image
2) We had already warned several times about the risks of COVID-19 on sperm.

IS SARS-CoV-2 BECOMING "INVISIBLE"? The Hidden Truth Behind the Pandemic

As the world strives to move past the COVID-19 pandemic, a troubling narrative has emerged: the perception that SARS-CoV-2 is becoming "invisible." Image
2) Governments and communities are eager to return to normalcy, leading to a tendency to downplay the virus's severity. Reports of new infections and long COVID cases have been totally minimized, creating a false sense of security ...
3) ...that the virus is no longer a significant threat. However, this perception is not only a matter of public sentiment. The virus itself has evolved, most notably with the emergence of the Omicron variant. Recent research reveals that Omicron exhibits a remarkable ability ... Image

VIRUS TEAM-UP:
How SARS-CoV-2 Keeps Cells alive to Spread, Increase Disease Severity and Aid Influenza! 😰
advanced.onlinelibrary.wiley.com/doi/10.1002/ad…Image
2) This research shows that SARS-CoV-2, the virus that causes COVID-19, stops infected cells from dying. Normally, when cells die, it helps stop viruses from spreading. By keeping these cells alive longer, SARS-CoV-2 allows itself to multiply and also helps other viruses ... Image
3) ... like influenza A, grow more easily.
When someone has both SARS-CoV-2 and influenza A, the two viruses can make a person much sicker. The immune system gets overwhelmed, leading to more inflammation and damage to the lungs. Image

ENTROPY UNLEASHED:
How Viral Protein Interactions Drive Coronavirus Adaptation in Bats and Humans

Entropy, in a general sense, refers to the level of disorder or randomness in a system.
biorxiv.org/content/10.110…Image
2) When we talk about protein interactions and viral behavior, entropy can be viewed as a measure of how complex and varied these interactions are.

In the context of the study about coronavirus interactions in bat and human cells, here's a simplified breakdown. Image
3) **Complex Interactions**: The study identifies how proteins from the coronavirus interact with host cells (both bats and humans). These interactions can be highly ordered (low entropy) or more chaotic (high entropy). Image
