ChatGPT scores up to 97% on medical facts — yet fails to read symptoms. Experts like Ahmed Abdeen Hamed and Dr Andrew Thornton warn: AI can inform, not diagnose. The real challenge now? Using it responsibly in healthcare. #healthcare
AI performs well on facts, but fails when it comes to symptoms | ICT&health Global
An important explanation lies in the nature of the language ChatGPT uses. Even more worrying is that it does not indicate when it does not know something.

SARS-CoV-2 causes systemic vascular damage via viral proteins and immune dysregulation, driving acute organ failure and Long COVID.

Vaccination reduces these risks significantly.
davidlingenfelter.substack.com/p/the-vascul...
🧬 FOR IMMEDIATE RELEASE SARS-CoV-2 Confirmed as a Vascular Pathogen: New Report Details Mechanisms Behind Acute and Long-Term Damage August 18, 2025 — El Cerrito, CA - A newly revised scientific report by David Lingenfelter, PhD, synthesizes global consensus and cutting-edge research to confirm that SARS-CoV-2 is not merely a respiratory virus—it is a systemic vascular pathogen. The report, originally generated via Google’s Gemini AI and refined through critique and reanalysis, offers a comprehensive account of the virus’s multifaceted assault on the vascular system. 🔍 Key Findings: • Endothelial Dysfunction as Central Pathology: SARS-CoV-2 disrupts vascular homeostasis via Spike protein–ACE2 interactions, Nucleocapsid protein–TLR2 signaling, and immune-mediated inflammation. • Microvascular Injury Drives Organ Failure: COVID-19-associated coagulopathy (CAC), microthrombosis, and vasculitis contribute to acute morbidity and mortality. • Long COVID Linked to Persistent Vascular Damage: Chronic endotheliopathy, fibrinaloid microclots, and senescent “zombie cells” underlie post-acute sequelae. • Vaccination Reduces Vascular Risk: Comparative data show significantly lower rates of cardiac complications post-vaccination versus post-infection. 🧠 Implications for Clinical Practice and Public Health: • COVID-19 should be classified as a systemic vascular disease. • Diagnostic protocols must incorporate endothelial biomarkers and advanced imaging. • Therapeutic strategies should target inflammation, thrombosis, and senescence. • Long-term surveillance is needed to assess cardiovascular risk in survivors. 📚 Future Directions: The report calls for randomized trials of senolytics, microclot-targeting therapies, and personalized vascular risk profiling. It also urges public health systems to prioritize vascular health as a pandemic preparedness measure. 🔗 Full report available on https://davidlingenfelter.substack.com/p/the-vascular-pathophysiology-of-sars-b2d
