Clonorchiasis is caused by ingestion of raw freshwater fish containing infective larvae of Clonorchis sinensis. China harbours the largest number of people with C. sinensis infection.

Engagement of the National Institute of Parasitic Diseases in control of soil-transmitted helminthiasis in China.

Soil-transmitted helminthiases (STHs) have been widely transmitted in China and the control of STHs was initiated by NIPD-CTDR since its foundation. Three national surveys on STHs have been carried out in China, and the infection rate has dropped from 53.58% in the first national survey (1988-92) to 4.

National surveillance on soil-transmitted helminthiasis in the People's Republic of China.

Soil-transmitted helminths (STHs) are widely distributed and remain a public health problem in the People's Republic of China. Altogether, 301 counties across 30 regions were investigated during the national surveillance on STHs carried out in 2016 based on the modified Kato-Katz thick smear method to examine faecal samples. A total of 305 081 people were investigated with 7 366 (2.

Surveillance of clonorchiasis in China in 2016.

Clonorchiasis is an important food-borne parasitic disease in China, and infection with C. sinensis can cause hepatobiliary diseases. Comprehensive and systematic prevention and control of clonorchiasis requires the establishment of an effective surveillance.

Extensive disseminated cysticercosis: a case report in Yunnan province, China.

Background: Cysticercosis is spreading all over the world and it is a major health problem in most countries of Latin America, Africa, and Asia. Extensive disseminated cysticercosis is relatively rare and fewer than 120 case have been reported in the worldwide. We reported a rare case of extensive disseminated cysticercosis in Yunan province, China.

[Interpretation of (WS/565-2017)].

Ascariasis once was a common disease in rural areas of China. It is showed that the average infection rate of in China was 1.36% according to the results of the national survey of important human parasitic diseases in 2015.

[Status and working principals of soil-transmitted nematodiasis during new period in China].

The current status of soil-transmitted nematodiasis in China is analyzed. The achievements in prevention and control of soil-transmitted nematodiasis are illustrated. Moreover, the challenges in condition of the decline of soil-transmitted nematodiasis in China are demonstrated.

Effect of integrated control intervention on soil-transmitted helminth infections in Jiangxi province in southeast China.

Soil transmitted helminths (STHs) burden was enormous in China several decades ago, however, rigorous control efforts have been successful with appreciable reduction in diseases burden. Here, we assessed provincial-level data derived from cross sectional surveys, executed in 1989, 2002 and 2014, on the prevalence of STHs among populations in Jiangxi province, China. This study, also, reported STHs integrated control intervention aimed at reducing STHs transmission and worm burden among population at county-level.

Assessment of health education products aimed at controlling and preventing helminthiases in China.

Background: Helminthiases have placed a huge burden of disease on the population in China. However, widespread control activities have led to significant achievements. As health education has been widely disseminated and plays an important role in the control and elimination of these diseases, we collected health education products aimed at controlling and preventing helminthiases in China.

[Interpretation of Detection of Intestinal Helminthes-The Kato-Katz Method (WS/T 570-2017)].

The criteria for the Kato-Katz thick smear are compiled following the The criteria are composed of five chapters, including the range of application, terms and definitions, equipments, reagent materials, and testing procedures. Three informative appendices (identification of helminth eggs in human faeces, counting method of eggs in Kato-Katz thick smear, and other considerations) are appended. The criteria have been issued by the National Health and Family Planning Commission of the People's Republic of China, it provides a technical reference for the detection of helminth eggs in human faeces in medical institutions and disease prevention and control institutions.

[Design and implementation of field questionnaire survey system of taeniasis/cysticercosis].

A taeniasis/cysticercosis information management system was designed to achieve the dynamic monitoring of the epidemic situation of taeniasis/cysticercosis and improve the intelligence level of disease information management. The system includes three layer structures (application layer, technical core layer, and data storage layer) and designs a datum transmission and remote communication system of traffic information tube in Browser/Server architecture. The system is believed to promote disease datum collection.

[Interpretation of Diagnostic Criteria for Clonorchiasis].

infection is carcinogenic to human, which results in cholangiocarcinoma, confirmed by the World Health Organization. An investigation in 2005 indicated that the standardized infection rate was 0.58%, with 12 490 000 infected people estimated in the clonorchiasis endemic areas in China.

Performance evaluation of existing immunoassays for Clonorchis sinensis infection in China.

Background: Clonorchiasis ranks among the most important food-borne parasitic diseases in China. However, due to low compliance to traditional fecal examination techniques in the general population and medical personnel, immunodiagnosis is expected. This study evaluated, in parallel, the performance of four immunodiagnostic kits detecting clonorchiasis in China.

New insights on serodiagnosis of trichinellosis during window period: early diagnostic antigens from Trichinella spiralis intestinal worms.

The clinical diagnosis of trichinellosis is difficult because its clinical manifestations are nonspecific. Detection of anti-Trichinella IgG by ELISA using T. spiralis muscle larval excretory-secretory (ES) antigens is the most commonly used serological method for diagnosis of trichinellosis, but the main disadvantage is false negativity during the early stage of infection.
