So much of the post-covid health issues that people are having really seems to hinge on the fact that bodies are fascinating and complicated interconnected systems - start knocking stuff over and you're likely to cause damage down the line *somewhere*. I'm honestly not sure if appendicitis will really ever be properly proven to be linked to covid, but if they get really great coverage for vaccines in the near future and the appendicitis rates go down in the next year, maybe that would do it.
