Anisakiasis

Anisakiasis is a disease caused by the third stage larvae of the genus Anisakiasis in the gastrointestinal tract. People are infected by eating raw fish that contains live larvae. The clinical manifestations of the acute phase include severe abdominal pain, nausea, vomiting, diarrhea and other gastrointestinal symptoms, accompanied by an increase in eosinophils; the chronic phase is characterized by eosinophilic granuloma of the stomach or intestine, which can be complicated by intestinal obstruction, intestinal perforation and peritonitis. The disease is more common in countries that eat sashimi, such as Japan, Europe and the United States. No cases have been reported in China, but the third-stage larval infection rate of anisakis in offshore fishes on the southeast coast is high. Anisakiasis is a second-class parasitic disease that is prohibited in China.
