>Flu doesn't usually have this sort of impact, people fully recover. I legitimately cannot stand this flu meme any more. I'll quote Charles Stross: "Remember, this isn't a simple pneumonia bug. It's a virus that attacks the RAAS/ACE2 system, in particular all the epithelial tissues, and any other cells that express ACE2 receptors on their surfaces. It can mess with your kidneys. It can mess with fat cells, changing their response to insulin. It apparently shows up in brain tissue. Viral RNA can be found in all of these cells many months after recovery from the acute infection: it may have long-term sequelae, like Shingles, which only show up years to decades later. We do know long COVID effects up to 15% of people who are diagnosed with an infection, and can last months to years. We know that immunity is short-lived, and people can get repeat infections (currently mostly by new strains, but reinfection with an old strain is not impossible)." The ace2 system that covid-19 attacks plays a vital role in the regulation of the cardiovascular system, and this has been known since 2020. https://www.nature.com/articles/s41569-020-0360-5 https://www.nature.com/articles/s41569-020-0360-5
