I've been saying this since Mar 2020, when COVID caused lymphocytopenia in the first month of my infection. Once I was finally able to get a lymphocytes subsets panel in Dec 2020, I shared my knowledge but couldn't find an audience who'd listen. No one wanted to believe

This is a direct result of immune suppression due to Covid infection. HIV does the same thing.

“As the Kansas and Missouri medical communities prepare for respiratory illness season, health officials grapple with an early COVID-19 infection spike and higher-than-normal tuberculosis infections in Wyandotte County.”

Study from California State University analyzed immune responses to 35 viruses using data from 219 datasets.

Findings show SARS-CoV-2 triggers a unique cytokine-chemokine profile, distinct from other viruses.

I’m sure everyone has seen it by now, but I suspect there is a lot of confusion about the paper and the information presented. This thread hopefully clears things up a bit.

Excellent explanation of mechanism discussed in recent SarsCov2 causing AIDS paper.

“So, to recap: Researchers identified two genotypes of the SARS-CoV-2 nucleocapsid protein that are able to use CD147 on host lymphocytes to infect those cells, and explain how that could contribute to immune deficiency and viral persistence (by citing independent research).”

I've had lymphocytopenia from COVID since March 2020. My T and B cells are low. I catch infections easily; latent infections reactivate. Spike protein & continued + RAT tests point to viral persistence. This is acquired immune deficiency.

Covid causes long-term reduction of immune system cells." Significantly, researchers found those infected (who had mild symptoms) had similar immune function to the non-infected group 10 weeks post-covid, but much reduced immune function at 10 months

"Tuberculosis after recovering from COVID-19 is becoming more common, potentially leading to a TB outbreak in the post-COVID-19 era."

‘“Tuberculosis after recovering from COVID-19 is becoming more common, potentially leading to a TB outbreak in the post-COVID-19 era.’

In only 3 years we discovered this.

HIV, discovered in 1981? Took until the early 90s.

And yet, the @CDC_TB never tells people to avoid C0Vid.”

T-Cell-Derived 3-Gene Signature Distinguishes SARS-CoV-2 from Common Respiratory Viruses

This is YET ANOTHER study showing SARS-CoV-2 adversely impacts the immune system.

Monocyte abnormalities (decreases) were found in BOTH symptomatic and asymptomatic SARS-CoV-2 infections. Because monocytes INCREASE in normal immune response, this suggests monocyte infection.

Evasion of NKG2D-mediated cytotoxic immunity by sarbecoviruses
A NEW study shows that cells infected with SARS-CoV-2 downregulate important immune signals known as NKG2D ligands. These ligands play a crucial role in activating the immune system, particularly natural killer (NK) cells, which are central to fighting viral infections.

Case Study update: Update. 8 weeks since this patient's mild COVID infection. CD4 down 21 to 276. CD4/CD8 ratio down to 0.8. No idea the frequency and duration of this in the general population. All I can say is this is not the only patient I've seen this in.

Anecdote: "My absolute lymphocytes count is below 1 again. My lymphocytes subsets are as bad or worse as they were in 2020. Numbers had normalized in 2022 with Evusheld. So far as I know, I haven't been reinfected. It's not #HIV, but it's acquired immune deficiency. #LongCOVID #AIDS"

Case Study: I’ve got another, mid 60s. In hospital 3 times for FUO. Finally gets Dx coccidioidomycosis septicemia. COVID in February. Persistent lymphocytopenia since then. CD4/CD8 pending but pretty sure what it’s going to show. Worried how often this is going to happen.
