"Here we show that Omicron subvariants were effectively inactivated by green tea, Matcha, and black tea and strongly suppressed infectivity of BA.1 and XE subvariants, while effect on BA.2.75 was weaker" nature.com/articles/s4159…
2) Decrease in infectivity of omicron subvariants by treatment with tea

3) Inhibition of the interaction of BA.1 RBD with ACE2

4) Fig. Structural comparison of TFDG binding with the Omicron RBD.
5) Inactivation of BA.1 Virus in vitro by Saliva from Volunteers Who Consumed a Candy Containing Tea. Healthy volunteers consumed a placebo candy (without tea) or a candy containing either green tea or black tea for 5 min
6) DISCUSSION
Each subvariant showed different sensitivity to catechins and theaflavins. This may be due to various amino acid substitutions in the RBD of the S protein of each subvariant.
The study may suggest molecular basis for potential usefulness of tea catechins and ...

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."
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 ...
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 ...
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.
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…
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.
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).
Patients care most about how COVID-19 affects their health and daily life, including for those with long COVID. Scientists focus on understanding the virus to find better treatments. Both views are important for dealing with the pandemic.
2) I'm bringing up this topic because, after talking so much about the disease, its long-term effects, treatments, and vaccines, many people have forgotten that we are dealing with the most dangerous virus humanity has ever faced.
Organelles provide the possibility for the virus to organize its RNA in PROTECTED structures, concentrate REPLICATION machinery ... nature.com/articles/s4146…
