COVID-19 worsens Autoimmune Diseases! Study reveals 30 percent spike in antinuclear antibody positivity
“new study has revealed shocking details about the long-term health impacts of COVID-19, particularly concerning autoimmune diseases. The study conducted by Metropolis analyzed data from over 1.2 lakh cases, comparing two critical periods—2019 (pre-COVID) and 2022 (post-COVID). The findings revealed a striking 30% increase in the prevalence of Antinuclear Antibody (ANA) positivity in the Indian population, indicating how the immune system may, in some cases, turn against the body’s own tissues following a COVID-19 infection.”
Multi-ancestry GWAS of Long COVID identifies immune-related loci and etiological links to chronic fatigue syndrome, fibromyalgia and depression
“Using consented and genotyped data from 23andMe adult research participants, we conducted the largest multi-ancestry meta-analysis of genome-wide association studies of Long COVID across European (42,899 cases, 94,721 controls), Latinx (8,631 cases, 20,351 controls), and African-American (2,234 cases, 5,596 controls) genetic ancestry groups. GWAS of Long COVID identified three genome-wide significant loci (HLA-DQA1 and HLA-DQB, ABO, BPTF:KPAN2:C17orf58). Functional analysis of these genes points to underlying immune and thrombo-inflammatory mechanisms.”

Father prepares to lay his daughter to rest after COVID-19 complications a month after testing positive
“Amid a rise in COVID-19 cases in Alabama, one father in Arely is preparing to lay his daughter to rest.
Byron Farmer said his daughter Amber tested positive for covid about a month ago, but she just died unexpectedly from complications on Wednesday. After she came down with COVID-19, Byron told WVTM 13 his daughter never fully recovered”

Mild Primary or Breakthrough SARS-CoV-2 Infection Promotes Autoantibody Production in Individuals with and without Neuro-PASC | ImmunoHorizons | American Association of Immunologists
“In this study, we demonstrate that mild SARS-CoV-2 infection increases autoantibodies associated with rheumatic autoimmune diseases and diabetes in most individuals, regardless of vaccination status prior to infection…
…These data highlight the need for additional strategies to decrease the spread of SARS-CoV-2 such as the development of vaccines that can prevent infection rather than decrease severity of acute disease alone.”
Yes, it’s not mild. I can tell this with my own ordeal.
