Eating raw food, drinking cold water is easy to be infected with dragon worms

Doctors said that dragonworm disease, scientifically known as Dracunculus medinensis, causes disease in humans and animals.

Dragonworm disease is transmitted through the gastrointestinal tract and enters the body through drinking water or food such as rare, live aquatic animals (fish, frogs, frogs, shrimp…) containing dragonworm larvae. Anyone of any age can be infected, and the incidence can be as high as 60%.

This is a roundworm, the longest in the group of worms infecting humans, adult female worms are 1-2 mm wide, about 70-120cm long, each female worm can carry up to 3 million larvae, male worms 4cm short. , died after mating with female worms.
