COVID-19 (SARS-CoV-2) can directly infect heart tissue.

"Researchers from the Centenary Institute and the University of Technology Sydney (UTS) have developed a human heart cell model demonstrating that the virus that causes COVID-19 (SARS-CoV-2) can directly infect heart tissue, providing new insight into why some people experience serious heart complications during and after infection."

Screenshot of an article dated March 3, 2026 titled “‘Mini hearts’ show COVID-19 virus directly infects heart tissue” by the Centenary Institute. Below the headline are four labeled microscope images (A–D) showing laboratory-grown heart tissue (“mini hearts”). The images use fluorescent colors—green, yellow, red, and white—to highlight cells and viral infection patterns, illustrating how SARS-CoV-2 can infect and spread through heart muscle cells in the tissue samples.

RE: aus.social/@DenisCOVIDinfoguy/

Can't believe this is actually news in 2026 when I distinctly remember a scientist talking about seeing covid shred heart muscle fiber cells literally in March 2020 on twitter. Which was the point where I decided I would try my best to never get this disease

Are we just going to keep "rediscovering" how bad covid is every few years while doing jack shit about it?
