Lovers of steaks with blood have the most chances to bring a close acquaintance with the chain since the parasite enters the body with uncooked meat. The tapeworm itself behaves more or less decently, does not devour its victim from the inside, and does not suck the blood out of it. Maybe he would like to, but he cannot. Because he has no digestive tract. So a person has to eat and digest, and the worm simply absorbs nutrients through the surface of the body. And it grows. It can reach up to eight meters. It is quite easy to etch a tapeworm today, the main thing is not to self-medicate and, as soon as symptoms of helminth infection appear (weight loss, weakness, dizziness), go to the doctor.
