Interesting, I'm noticing this pattern too more and more. The classic case was of course stomach ulcers. Now cardiovascular. Wouldn't be surprised if at least some neuro-degnerative diseases are also possibly caused by infections
Now we're seeing more colon cancer in young people. All of the discussion is around factors that change slowly (diet, alcohol, exercise), no one I've heard has pointed out that a pathogen would explain a quick change.
