SARS-CoV-2 causes more damage to your immune system than HIV. Both viruses induced a reduction in B cells and CD4+ T cells, but SARS-CoV-2 infection caused a more severe reduction in total T cells, CD8+ T cells, and NK cells than HIV infection.

SARS-CoV-2 can infect inner ear cells, specifically hair cells and Schwann cells, which are crucial for hearing and balance. Some COVID-19 patients developed hearing loss, tinnitus, and vertigo, suggesting a link between the virus and these symptoms. nih.gov/news-events/ni…

Why are people so sick? Something big changed in 2020. What could it have been? It seems like it's on the tip of my tongue; something that rhymes with Mars.

SAR-CoV-2 damages kids' blood vessels. "Children infected with SARS-CoV-2 show elevated levels of a biomarker tied to blood vessel damage. Many examined children testing positive for SARS-CoV-2 are being diagnosed with thrombotic microangiopathy."
Virtually all children infected with COVID-19 show signs of blood vessel damage, study shows
