Once people eat uncooked or raw "sick fish", the sparganosis that parasitizes in the fish will develop into adults in the human body and cause fish ichthyosis. It will not be transmitted from human hands. If the fish is fully cooked, the sparganosis can be killed and will not cause infection. When people are infected with this type of red worm disease, the gastrointestinal symptoms are usually not obvious, and usually only include fatigue, weakness, diarrhea or constipation, numbness of the limbs, hunger, salt addiction and other discomforts. In severe cases, anemia or severe anemia may occur, and even the patient may lose the ability to work.
