[Effect of health education on prevention from schistosome infection in engineering construction workers in Poyang Lake area].

Objective: To evaluate the effect of health education on prevention from schistosome infection in engineering construction workers in Poyang Lake area.

Methods: The workers for constructing "De Chang" highway in Poyang Lake area were divided randomly into an experiment group and a control group, "health education + protective skill training" was carried out in the experiment group, whereas, no intervention was implemented in the control group.

Results: In the experiment group, the awareness rates of schistosomiasis control knowledge were 7.

Impact and cost-effectiveness of a comprehensive Schistosomiasis japonica control program in the Poyang Lake region of China.

Schistosomiasis japonica remains a significant public-health problem in China. This study evaluated cost-effectiveness of a comprehensive schistosomiasis control program (2003-2006). The comprehensive control program was implemented in Zhangjia and Jianwu (cases); while standard interventions continued in Koutou and Xiajia (controls).

[Evaluation on effect of schistosomiasis control after attainment of criteria for infection control in Jinxian County].

Objective: To understand the schistosomiasis epidemic situation after the attainment of criteria for infection control, and evaluate the effect of control measures in Jinxian County, Jiangxi Province.

Methods: The data of schistosomiasis epidemic situation including the infection rates of residents and Oncomelania snails were collected and analyzed statistically in the infection-controlled, transmission-controlled, and transmission-interrupted areas in Jingxian County from 2008 to 2011.

Results: The antibody positive rates of population were decreasing year by year from 2008 to 2011 with the rate in the infection-controlled area being higher than the rates in the transmission-controlled and the transmission-interrupted areas.

[Investigation on transmission factors of schistosomiasis after replacement of bovine with machine in Jinxian County].

Objective: To understand the changes of transmission factors of schistosomiasis after the control strategy of replacing bovine with machine was implemented in the lake region, so as to provide the evidence for long-effective management in marshlands.

Methods: Two villages, which had carried out the control measure of replacing bovine with machine, were selected as observed villages. The data of endemic situation before and after the replacement were collected and analyzed.

[Comparison of fecal examinations and worm collection results in an investigation of Ascaris lumbricoides infection].

Objective: To explore the relationship between fecal examinations and worm collection results in a community investigation of Ascaris lumbricoides infection.

Methods: A total of 1 019 residents in Zhangxi Village, Nanchang County, Jiangxi Province were investigated with the Kato-Katz technique and worm collection after deworming.

Results: Among 1 019 residents investigated, the actual prevalence of A.

[Evaluation on medium-term effect of schistosomiasis comprehensive control strategy based on infectious source control in Poyang Lake area].

Objective: To evaluate the medium-term effect and stability of the schistosomiasis comprehensive control strategy based on infectious source control after its popularization and application in marshland endemic areas.

Methods: The schistosomiasis comprehensive control strategy based on infectious source control including "replacing buffalo with machine", "marshlands isolation and grazing forbidden", etc. was implemented in all villages of Sanli Township, a heavy endemic area with schistosomiasis in Jianxian County.

[Effects of reclaiming and cultivation in marshland on Oncomelania snail control].

The changes of snail situation in the marshlands and the economic benefit of planting were investigated after planning sesame on marshlands above 16 meters' elevation in Poyang Lake at drought period in autumn and by comparing three groups, i.e. planting sesame alone, planting sesame plus fertilizing "Rong Bao" (a brand of one fertilizer), and no planting.

[The effect and influencing factors of schistosomiasis control by forbidding livestock denaturing on marshland with Oncomelania snails].

Objective: To evaluate the effect of schistosomiasis control by forbidding livestock denaturing on marshland with Oncomelania snails and to analyse its influencing factors.

Methods: The village of Aiguo, Xinhe, Huangjia, Fanrong, Fengfu and Caomen and its respective nearby marshland, i.e.

[Cost-effectiveness and cost-benefit analysis on the integrated schistosomiasis control strategies with emphasis on infection source in Poyang Lake region].

Objective: To evaluate the cost-effectiveness and cost-benefit on the integrated schistosomiasis control strategies with emphasis on infection source, and provide scientific basis for the improvement of schistosomiasis control strategy.

Methods: Aiguo and Xinhe villages in Jinxian County were selected as intervention group where the new comprehensive strategy was implemented, while Ximiao and Zuxi villages in Xinzi County served as control where routine control program was implemented. New strategy of interventions included removing cattle from snail-infested grasslands and providing farmers with farm machinery, improving sanitation by supplying tap water and building lavatories and methane gas tanks, and implementing an intensive health education program.

A strategy to control transmission of Schistosoma japonicum in China.

Background: Schistosoma japonicum causes an infection involving humans, livestock, and snails and is a significant cause of morbidity in China.

Methods: We evaluated a comprehensive control strategy in two intervention villages and two control villages along Poyang Lake in the southeastern province of Jiangxi, where annual synchronous chemotherapy is routinely used. New interventions, implemented from 2005 through 2007, included removing cattle from snail-infested grasslands, providing farmers with mechanized farm equipment, improving sanitation by supplying tap water and building lavatories and latrines, providing boats with fecal-matter containers, and implementing an intensive health-education program.

[Impact of a reservoir project on schistosomiasis transmission in lake region].

Objective: To determine the impact of a project of building dike for storing water on schistosomiasis transmission in Junshan Lake.

Methods: Junshan Lake in Jinxian County of Jiangxi Province was selected as survey pilot. Data on snail distribution and historical prevalence of schistosomiasis before building dike were collected.
