Guinea worms aren't that bad. It is only isolated to a certain portion of the undeveloped world. You drink impure water, bad sanitary habits, this is what you get.
Naegleria fowleri, aka the brain flesh eating amoeba (but doesn't really eat it) is way worse, it's hard to treat and people die (in the states) every year due to it. It's just uncommon since we are a developed country in the US.
I believe most if not all internal worms reproduce dropping their proglottids or eggs into the feces. Some even pop their heads out of a rectum at night (see pinworms).
Animals in the US, especially pets are prone to these parasites. Due to the feral pets wandering around, or consuming unsafe foods. Some can be transmitted to humans after that, or they share a common vector. Walking barefooted is another common way to get them.
Imo, worm curing is fairly easy. There are lots of different treatment that are extremely effective, killing the worms in matters of hours or days while the dead matter passes out into the feces.
