This sounds like it should be easy to treat, but that it is not being detected.
How does the tapeworm inhabit the brain in the first place? Eating meat that it not thouroughly cooked?
Yes. The answers are in the text as to how they reach the brain.
Yes. Eating undercooked pork. I don't know if that is the only way, but it's certainly, by far, the main way, the principle way, one becomes infected.
It seems like undercooked pork can give you the larvae and the tapeworm, which seem to stay in your intestines. But it is swallowing an EGG that causes the brain infection (and elsewhere I imagine). And it seems that the only way to swallow an egg is from a human’s unclean hands or fece’s contaminated food (ANY kind of food).
An edited portion from the article:
The EGGS are shed in the infected PERSONS’s feces....When the parasite EGGSs reach a pig’s stomach, larvae hatch and burrow their way into the animal’s bloodstream....There they form CYSTS and wait until their host is eaten by a human. (Pork has to be undercooked for the tapeworms to complete their journey.)
But sometimes tapeworms take a wrong turn. [Previous sentence is stupid - the PERSON DID NOT WASH THEIR HANDS, and they are talking about the EGGS, not the tapeworms]. Instead of going into a pig, the EGGS end up in a human. This can occur if someone shedding tapeworm eggs contaminates FOOD that other people then eat. When the egg hatches,.........the larva burrows into the person’s bloodstream and gets swept through the body. Often those parasites end up in the brain, where they form cysts....
