At present, there are about 15 million People infected with Chinese mycodchiasis worldwide, mainly in China, South Korea, Vietnam and Russia. Among them, there are nearly 13 million infected people in China, ranking first in the world, accounting for more than 85% of the total, and there is still an increasing trend. Qian Menbao, assistant researcher of the Institute for The Prevention and Control of Parasitic Diseases of the Chinese Center for Disease Control and Prevention, and Zhou Xiaonong, director of the Institute, and York Josinger, director of the Swiss Institute of Tropical Diseases and Public Health, and Dr Jennifer Kaiser, co-authored a review article on trematodiasis in China over the past 140 years, mentioning the above data. The article was recently published in the online edition of The Lancet.
Chinese mycarditrium, also known as hepatic flukes, is a freshwater fish parasite, more than 100 species of fish can be infected, cats, dogs are important carnivod hosts. If a person eats raw freshwater fish infected with the larvae of Copidis cerevis, the cysticercosis, they will be infected with Mycodystis.
The review article pointed out that the chinese mycodystis infection is mainly distributed in Guangdong, Guangxi, Heilongjiang and Jilin, and the infection rate and infection rate of men are higher than those of women, and the trend of increase with age is increasing. Zhou Xiaonong said that eating raw fish has gradually become a food culture in many regions, but the public knows little about the risks and dangers of Chinese mycosomiasis. "In the high-prevalence counties of Guangdong and Guangxi, the infection rate of the population exceeds 50%, and almost all local adult men are infected."
According to Zhou Xiaonong, people with low-grade Infection of Chinese mycanthida usually have no obvious symptoms or only mild symptoms in the early stage. If not treated in time, with the increase in the number of raw fish eaten, the number of bugs in the body accumulates, and severely infected people can have a series of non-specific digestive and nervous system symptoms, such as poor appetite, fatigue, diarrhea, abdominal pain, dizziness, headache, etc. Long-term chronic infection can cause a variety of hepatobiliary system complications, such as liver enlargement, gallbladder enlargement, gallstones, cholecystitis, cholangitis and cholangiocarcinoma. Severe infection in children can cause dwarfism. In 2009, the International Agency for Research on Cancer identified Trebudchiatia sinensis as a Class 1 carcinogen for cholangiocarcinoma. Studies have shown that the risk of cholangiocarcinoma in people infected with Cholangiodiasis is 4.5 to 6.1 times that of non-infected people.
Zhou Xiaonong pointed out that China's Chinese mycosomiasis prevention and control capacity is weak, we must increase health education, environmental remediation, strengthen cooperation between disease control departments and medical and health institutions, and jointly formulate Chinese mycodychiasis prevention and control strategies. The most urgent task is to increase health education and science popularization so that the public does not eat freshwater fish raw. "Traditional human and animal manure fish farming patterns will also promote the epidemic of Floral testicles, so environmental remediation will help reduce the epidemic of Trebustomyces."

Condiments cannot kill insects
"Eating freshwater fish raw has become a determinant of the epidemic of Warfarinomal fluke disease. Ordinary people lack understanding of the risks and harms of this disease, and many people think that condiments such as alcohol and pepper can kill insects, which is wrong. Transmission can only be interrupted by high temperature heating, and heating at temperatures above 90 degrees Celsius for a few seconds can kill cysticercosis. Qianmenbao reminded that "raw food families" should be extra vigilant against various parasites, such as eating uncooked pork can cause trichinellosis, tapeworm disease, raw beef can cause taeniasis, raw snails can cause Guangzhou roundworm disease, raw eating freshwater shrimp, crabs can cause lung trematode disease, etc.
Medications are available for treatment
Zhou Xiaonong introduced that the pathology of Trebudchiasis infection involves many aspects, such as the obstruction of bile ducts by insects, the damage to the mucosa of bile ducts caused by insect suction, the immunopathology caused by infection-related inflammation and the toxic effect of excretion-secretion products, but the exact carcinogenic mechanism has yet to be further elucidated. The Trematodes sinensis genome has been cracked, and the associated transcriptomics and proteomics studies will help to find new diagnostic methods.
According to Qianmenbao, confirmed liver fluke infection patients need immediate drug treatment, generally using praziquantel. The drug was introduced in the treatment of Trestanchicosis in the late 1970s and is currently the only recommended drug. In addition, albendazole also has a good effect on floral testosteriasis, and the side effects are small, but the course of treatment is longer and needs to be used for 5 or 7 days. Recent studies have found that triphenylbizine is effective against Chondromydiasis and has advantages such as convenient administration and few side effects, but further verification is needed.
