🧵What’s the difference between XBB.1.5 and XBB.1.16 that gives XBB.1.16 an estimated 200% growth advantage over XBB.1.5?
A concerning trend that has been gaining momentum is mutations in the body of the virus instead of the spike.
Even though XBB.1.5 is already avoiding antibodies, the immune system is still alerted to the infection. The mutations in XBB.1.16 could make things worse by messing up the signal that tells the immune system there's an infection. 2/
It may be shutting off the alarm system so the body doesn’t know there is an intruder. This could result in fewer symptoms while it infects immune cells and weakens the immune system, leaving people more vulnerable to infection from other viruses and bacteria. 3/
This may be contributing to the adenovirus & H3N2 surge in India.
”More than 3,000 children have been admitted to hospitals with severe flu-like symptoms”
“The Association of Health Service Doctors warns that the numbers of deaths and cases are likely to be much higher" 3/
The XBB variants are more likely to cause persistent infections raising the risk of diabetes, heart attacks, strokes, GI issues, brain damage, early onset dementia, autoimmune disorders, and a variety of other long-term health issues. 4/
Local media reports put the death toll at more than 100 children. The state’s healthcare system is struggling to cope. Some hospitals' pediatric wards are full.
The “officials” are reporting that this is caused by “two mutated adenovirus strains.” 5/ ⬆️ ⬆️
They say that this adenovirus is also found in Maharashtra and Karnataka. Coincidentally, the same states have rapidly increasing cases of XBB.1.16.
Adenovirus & influenza are likely taking advantage of & mutating in suppressed immune systems during & following infections.

We already have studies showing how COVID can infect CD-4 T-cells, dendritic cells, and neutrophils. We know that COVID has been listed as one of the leading causes of Lymphocytopenia. 7/
COVID impacts everyone’s immune system to varying degrees. Some people recover faster than others, but it can take weeks to more than eight months to recover. 8/

Why are mutations in ORF9b particularly concerning?
This study concludes that their findings “unveil the innate immunosuppression by ORF9b.” 10/
XBB.1.9.1 is showing up with mutations, Orf3a:A23V and N:L331F. Mutations in Orf3a may be even more dangerous.
There are a lot of ways this virus can get much more dangerous. People will get caught in the line of fire. This is NOT the time to let your guard down. #N95Maskswork

NHS worker, 24, dies suddenly at home
Her death has rocked the local community, who described her as the "life and soul of the party" who "never had a smile off her face". - no cause of death listed

Fungal infections with Candida auris increased from 756 in 2020 to 1,471 in 2021. Preliminary figures count at least another 2,377 cases for 2022. 30 states & the District of Columbia have now reported Candida auris patients.
COVID is listed as one of the leading causes of Lymphocytopenia.
"People with lymphocytopenia experience recurrent infections or develop infections with unusual organisms & it is a risk factor for the development of cancers & for autoimmune disorders."
In India, Union Health Secretary Rajesh Bhushan has said in a letter sent to six states, Maharashtra, Gujarat, Telangana, Tamil Nadu, Kerala and Karnataka, to follow a risk assessment-based approach to prevent & contain the spread of COVID-19 infections.
XBB.1.16 has been sequenced in the U.S. and the U.K.
NY, WA, CA, FL, IL, TX, England, Northern Ireland, Wales should all be paying close attention to new outbreaks and increasing hospitalizations.
This variant has a significant growth advantage over XBB.1.5
XBB.1.16 growth advantage went up since the pic below to 227% but this will fluctuate as more data is acquired. This is far above any of the XBB.1.5 subvariants. At the low end of the spread, it would have a 100% advantage, 5 x greater than XBB.1.5.10 What changed?
