Want to know what’s worse than a tapeworm? A roundworm! This deadly worm kills even more people per year than the tapeworm and can easily be mistaken for the humble (and ever so useful) earthworm: only the roundworm is nothing like the earthworm in function.
When it infects a human or dog, it is incredibly persistent and hangs on for dear life, hatching up to 100,000 eggs in a single day! It then roams around your body, makes itself at home before settling down in your large intestine where it plans to wreck havoc with your body before eventually killing you if you don’t do something about it.
