Objective: To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022, so as to provide insights into formulation of echinococcosis control measures in the prefecture., Methods: Villagers were randomly sampled using a multistage sampling method from class I and II echinococcosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococcosis, while all patients undergoing ultrasound examinations in medical institutions in class III endemic counties received active echinococcosis screening. In addition, livestock in centralized slaughterhouses or slaughtering sites were screened for echinococcosis using the palpation and necropsy method, and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs. The trends in detection of human and livestock echinococcosis, detection of newly diagnosed human echinococcosis cases and detection of Echinococcus coproantigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022., Results: The mean detection rate of human echinococcosis was 0.13% (540/407 803) in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022, which appeared a tendency towards a decline over years (χ 2 trend = 1 217.21, P < 0.001), and the highest detection of newly diagnosed echinococcosis cases was seen in Hejing County (0.28%, 191/67 865). The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022 (χ 2 trend = 147.02, P < 0.001), with the highest detection rate seen in Hejing County (3.44%, 86/2 500), and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022 (χ 2 trend = 302.46, P < 0.001), with the highest detection rate in Qiemo County (2.74%, 118/4 313)., Conclusions: The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022; however, there is still a high echinococcosis transmission risk in local areas. Sustainable integrated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.

Objective: To evaluate the effectiveness of comprehensive echinococcosis control measures with emphasis on management of infectious source in Sichuan Province from 2010 to 2022, so as to provide insights into formulation of future control interventions., Methods: Data pertaining to comprehensive echinococcosis control measures with emphasis on management of infectious source and echinococcosis surveillance in Sichuan Province from 2010 to 2022 were collected. The effectiveness of comprehensive echinococcosis control measures with emphasis on management of infectious source was evaluated with prevalence of human echinococcosis, detection of newly diagnosed echinococcosis patients, prevalence of Echinococcus infection in domestic dogs, prevalence of cystic echinococcosis in livestock, prevalence of alveolar echinococcosis in small mammals and awareness of echinococcosis control knowledge, and Spearman's rank correlation analysis., Results: The prevalence of human echinococcosis reduced from 1.08% in 2010 to 0.40% in 2022 in Sichuan Province (χ 2 = 1 482.97, P < 0.05), with a reduction from 0.30% to 0.02% in the detection of newly diagnosed echinococcosis cases (χ 2 = 2 776.41, P < 0.05), a reduction from 15.87% to 0.46% in the prevalence of Echinococcus infection in domestic dogs (χ 2 = 20 823.96, P < 0.05), a reduction from 8.05% to 1.07% in the prevalence of cystic echinococcosis in livestock (χ 2 = 1 296.02, P < 0.05), and the awareness of echinococcosis control knowledge increased from 50.65% to 95.24% (χ 2 = 34 938.63, P < 0.05); in addition, there was a year-specific prevalence rate of alveolar echinococcosis in small mammals (χ 2 = 164.07, P < 0.05). Spearman's rank correlation analysis revealed that the detection of newly diagnosed echinococcosis cases correlated positively with the prevalence of Echinococcus infections in domestic dogs ( r s = 0.823, P < 0.05) and the prevalence of cystic echinococcosis in livestock ( r s = 0.795, P < 0.05), and correlated negatively with the awareness of echinococcosis control knowledge ( r s = - 0.918, P < 0.05), and the prevalence of Echinococcus infection in domestic dogs correlated positively with the prevalence of cystic echinococcosis in livestock ( r s = 0.753, P < 0.05) and negatively with the awareness of echinococcosis control knowledge ( r s = -0.747, P < 0.05); however, there was no correlation between the prevalence of Echinococcus infections in domestic dogs and the prevalence of alveolar echinococcosis in small mammals ( r s = -0.750, P > 0.05)., Conclusions: The comprehensive echinococcosis control measures with emphasis on management of infectious source had achieved remarkable effectiveness in Sichuan Province; however, the transmission chain of echinococcosis has not been interrupted. Reinforced comprehensive echinococcosis control measures with emphasis on management of infectious source and sustained tracking evaluation of the effectiveness are recommended in Sichuan Province.

Objective: To evaluate the effectiveness of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, so as to provide insights into echinococcosis control., Methods: Administrative villages were sampled using a multi-stage cluster random sampling method from Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, and all residents at ages of 12 years and older in the sampled villages were screened for echinococcosis, and schools were sampled using a cluster sampling method, and all children at ages of 12 years and older in the sampled schools were screened for echinococcosis. Domestic dogs were sampled using a systematic random sampling method, and one domestic dog stool sample was collected from each household. Stray dog stool samples were collected outside the villages, and Echinococcus coproantigens were detected using enzyme-linked immunosorbent assay in domestic and stray dogs. In addition, echinococcosis was screened in sheep and cattle in designated slaughterhouses in Tianzhu Tibetan Autonomous County. The trends in the prevalence of echinococcosis in humans and livestock and the positive rate of Echinococcus coproantigens in dogs were examined with the Cochran-Armitage trend test. In addition, individuals screened for echinococcosis were randomly sampled from 2007 to 2022 for survey on the awareness of echinococcosis control knowledge., Results: A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ 2 = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ 2 = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ 2 = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ 2 = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ 2 = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ 2 = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ 2 = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ 2 = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively., Conclusions: There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.

China is one of the countries with the highest disease burden of echinococcosis in the world. China's progress in echinococcosis control started with limited scientific research projects, followed by nationwide epidemiological surveys, and then launched a national echinococcosis control programme on the basis of a pilot intervention project. During this process, science-based control and technological innovations have been integrated into echinococcosis control in China. The concept and mechanism innovations-based echinococcosis control models and successful experiences in highly endemic foci promote the sustainable echinococcosis control achievements in China. In addition, the joint echinococcosis prevention and control and sharing of successful experiences with other echinococcosis-endemic countries will provide China's wisdom, China's strategy and China's contributions to global echinococcosis control and the health of human beings.

Objective: To investigate the effectiveness of a new health education pathway for echinococcosis control among primary school students in regions highly prevalent for echinococcosis in China., Methods: Six primary schools were randomly selected from echinococcosis hyper-endemic regions, with 13 classes assigned to the intervention group and 9 to the control group, and all students in these 21 classes were recruited as the study subjects. Echinococcosis health education was performed through the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices in the intervention group, while routine health education was given in the control group. A questionnaire survey was performed to assess the score of echinococcosis control knowledge (including theoretical knowledge score and mean daily practical capability score) before and after the health education interventions to evaluate the effectiveness of this new health education pathway for echinococcosis control., Results: The mean score of echinococcosis control knowledge was 68.86 ± 18.70 points at baseline, with the mean theoretical knowledge score of 40.97 ± 10.75 points, and the mean daily practical capability score of 27.89 ± 12.50 points. Clustering analysis showed three types of populations, including "unsatisfactory", "learn and apply creatively", and "rote learning", which accounted for 24.62% (240/975), 45.74% (446/975) and 29.64% (289/975), respectively. The mean score of echinococcosis control knowledge was 81.08 ± 18.15 points in the intervention group during the final assessment, with the mean theoretical knowledge score of 43.65 ± 9.40 points, and the mean daily practical capability score of 37.43 ± 12.22 points, and both were significantly higher relative to baseline ( t = -4.201 and -15.202, both P values < 0.01). The mean score of echinococcosis control knowledge was comparable between at baseline (70.55 ± 19.46 points) and final assessment (71.74 ± 19.37 points) in the control group ( t = -0.87, P > 0.05)., Conclusions: The awareness of echinococcosis control knowledge is fair among primary school students in echinococcosis hyper-endemic regions; however, the capability of combining theoretical learning and practices requires to be improved. The health education mode based on the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices seems to remarkably improve the understanding of echinococcosis control knowledge among primary school students in echinococcosis hyper-endemic regions.

Objective: To evaluate the effect of the integrated echinococcosis control program in Ningxia Hui Autonomous Region from 2011 to 2018., Methods: A package of integrated interventions were employed for echinococcosis control in 22 counties (districts) of Ningxia Hui Autonomous Region from 2011 to 2018, including screening of human echinococcosis, treatment of echinococcosis patients, deworming of domestic dogs and monitoring of infections, surveillance of echinococcosis in bovines and sheep, health education. The detection of human echinococcosis, seroprevalence of anti- Echinococcus antibody in children at ages of 6 to 12 years, the Echinococcus coproantigen-positive rate in domestic dogs, prevalence of echinococcosis in bovines and sheep, and the awareness of echinococcosis control knowledge were investigated and compared during the period between 2011 and 2018., Results: The detection of human echinococcosis appeared a decline tendency in Ningxia Hui Autonomous Region over years during the period from 2011 to 2018 ( χ 2 trend = 82.22, P < 0.05), and the prevalence of human echinococcosis decreased from 0.31% in 2011 to 0.15% in 2018. The seroprevalence of anti- Echinococcus antibody appeared a decline tendency in children at ages of 6 to 12 years over years ( χ 2 trend = 439.64, P < 0.01), and the prevalence of anti- Echinococcus antibody decreased from 6.12% in 2011 to 0.67% in 2018. The Echinococcus coproantigen-positive rate appeared a decline tendency in domestic dogs over years ( χ 2 trend = 260.33, P < 0.05), and the prevalence of anti- Echinococcus antibody decreased from 7.11% in 2011 to 0.75% in 2018. The prevalence of bovine and sheep echinococcosis reduced from 3.26% and 5.08% in 2011 to 1.35% and 0.76% in 2018, and Echinococcus predominantly parasitized in bovine (92.00%) and sheep (93.94%) livers. A total of 63 stool samples were collected from red fox, wolf and badger in Xiji and Haiyuan counties of Ningxia Hui Autonomous Region in 2013 and 2014, with no Echinococcus coproantigen-positives detected, and 107 domestic cats and 3 domestic dogs were dissected in these two counties, with no Echinococcus found. A total of 6 046 wild mice were dissected in Xiji County, Yuanzhou District and Haiyuan County of Ningxia Hui Autonomous Region from 2016 to 2019, and the prevalence of E. multilocularis was 0.31%. The awareness of echinococcosis control knowledge appeared an increasing tendency in Ningxia Hui Autonomous Region over years from 2011 to 2018 ( χ 2 trend = 3 367.97, P < 0.01), and the awareness increased from 21.83% in 2011 to 72.24% in 2018., Conclusions: The integrated echinococcosis control program achieves a remarkable effect in Ningxia Hui Autonomous Region, and the transmission of echinococcosis has been preliminarily controlled. However, the echinococcosis transmission risk remains in few regions, and the integrated echinococcosis control program remains to be reinforced.

Objective: To understand the status of knowledge, attitude and practice on echinococcosis prevention and control and investigate their influencing factors among residents living in Seda County of Sichuan Province, so as to provide a scientific basis for the further implementation of health education interventions in the county., Methods: A multi-stage stratified random sampling method was employed on September 2018. Ten townships were randomly sampled, and 2 to 3 administrative villages were randomly sampled from each township. Then, 20 to 40 households were randomly sampled from each village, and 1 to 2 villagers were investigated in each household. The knowledge, attitude and practice on echinococcosis prevention and control were investigated using a household questionnaire survey, and the factors affecting the qualification of echinococcosis prevention and control knowledge were identified using chi-square test and logistic regression analysis., Results: A total of 760 questionnaires were assigned, and 748 effective questionnaires were recovered, with a recovery rate of 98.42%. The overall qualification rate of echinococcosis prevention and control knowledge was 56.42% (422/748) in residents living in Seda County, and the awareness of the question "How to get echinococcosis?" was only 48.40%. The proportion of subjects with a positive attitude towards echinococcosis prevention and control was 64.71% to 94.79%, and the rate of corrected echinococcosis prevention and control behaviors was 10.40% to 82.45%. Univariate analysis showed that factors affecting the qualification rate of echinococcosis prevention and control knowledge included gender, occupation, education level, frequency of echinococcosis screening and frequency of health education (all P < 0.05), and binary logistic regression analysis showed that women, herdsmen as the primary occupation, an education level of primary school and below, absence of echinococcosis screening and absence of health education were factors responsible for the unqualified awareness of echinococcosis prevention and control knowledge (all P < 0.05)., Conclusions: There is a low awareness rate of echinococcosis prevention and control knowledge and a low proportion of corrected echinococcosis prevention and control behaviors in residents living in Seda County, Sichuan Province. Multiple forms of health education activities pertaining to echinococcosis prevention and control are needed with adaptation to local circumstance, and implementation of appropriate behavioral interventions is recommended.

Objective: To explore the spatial and temporal distribution characteristics of cases with newly diagnosed echinococcosis in Sichuan Province from 2007 to 2017, so as to provide reference for the formulation of echinococcosis prevention and control strategies and for the identification of key areas., Methods: The spatial distribution maps of detection of cases with newly diagnosed echinococcosis were plotted in Sichuan Province from 2007 to 2017, and the spatial distribution characteristics and epidemic trends were analyzed., Results: From 2007 to 2017, the detection rate of cases with newly diagnosed echinococcosis appeared a decline in Sichuan Province year by year, and the areas with a high detection rate of cases with newly diagnosed echinococcosis were mainly located in western, northwestern and northern parts of Sichuan Province, while the areas with a low detection rate were predominantly found in the southern and eastern parts of the province. The global Moran's I values were 0.19, 0.22, 0.17, 0.44, 0.48, 0.31 and 0.16 for the detection rate of cases with newly diagnosed echinococcosis in Sichuan Province from 2010 to 2016 (all Z scores > 1.96, all P values < 0.05), suggesting spatial aggregation distribution during this period. Local spatial autocorrelation analysis revealed that the"high-high"areas and"low-low"areas for the detection rate of cases with newly diagnosed echinococcosis all showed an aggregation tendency., Conclusions: The detection rate of cases with newly diagnosed echinococcosis decreases in Sichuan Province from 2007 to 2017 year by year, and shows a spatial aggregation. The echinococcosis control activities should be intensified in Shiqu, Seda, Dege, Ganzi and Baiyu counties.

This article analyzes recent progresses on health education and health promotion targeting echinococcosis control in the major endemic foci of China, and describes the problems, including lack of human echinococcosis control knowledge, low human health literacy levels, incomplete establishment of health promotion mode, and urgent efforts to achieve the goal of Health for All. In addition, the feasible measures and strategies on health literacy promotion for echinococcosis control are discussed in combination with the national health literacy promotion strategy according to Healthy China 2030.

Objective: To understand the epidemiological characteristics of death cases of echinococcosis in China from 2008 to 2016, so as to provide an important reference for the prevention and control of echinococcosis., Methods: The death information registration and management system data were selected to analyze the epidemiological characteristics of the death cases of echinococcosis. The data were analyzed by SPSS 21.0 and the map was drawn by ArcGIS 10.1 software., Results: From 2008 to 2016, a total of 367 death cases of echinococcosis were reported in China, and the number of deaths in turn was 33, 30, 21, 32, 35, 54, 55, and 81 in each year, with an annual average crude mortality of 129.29 /10 5 . The average age of death was (56 ± 18) years; the sex ratio of male to female was 100∶94. There was no statistical difference between the male and female death cases ( χ 2 = 0.33, P > 0.05).The death cases of echinococcosis were mainly distributed in endemic areas of Qinghai, Sichuan, Ningxia, Xinjiang, Gansu, Inner Mongolia, Yunnan and non-endemic areas of Heilongjiang, Jiangsu, Henan and Shandong. The death cases in the first eleven provinces accounted for 87.5% (321/367) of the total death cases, among which the highest proportions of the nationality, occupation, educational level, highest diagnostic units, and the place of death were Han (52.0%, 191/367), farmer (46.6%, 171/367), junior high school or below (57.2%, 210/367), provincial or three-level hospitals (46.6%, 171/367), and at home (59.9%, 220/367)., Conclusions: Since 2014, the death cases of echinococcosis in China have been increasing year by year, indicating that the prevention and treatment of echinococcosis is still very serious. The causes for the rise of the fatality rate remain to be further studied.

Objective: To master the prevention knowledge and behavior of echinococcosis and the influencing factors in residents in agricultural and pastoral areas of Maerkang City, so as to provide the reference for formulating the policy and strategy of echinococcosis prevention and control., Methods: In April, 2017, 796 residents in agricultural and pastoral areas of Maerkang City were selected by the multi-stage stratified random sampling method, and surveyed with questionnaires. The main questions included the prevention knowledge and related behaviors of echinococcosis., Results: The awareness rate of prevention knowledge of echinococcosis was 70.1% (558/796). The awareness rate was the lowest in the group aged 15 to 25 years. The difference of knowledge awareness rate was statistically significant among the different age groups (χ 2 = 16.408, P < 0.01). The knowledge awareness rate of the people with middle school or above educational level was higher than that of the people with primary school or below educational level (χ 2 = 4.869, P = 0.027). The knowledge awareness rate of the dog owners was lower than that of the people without a dog (χ 2 = 11.384, P = 0.001). The knowledge awareness rate in the people who received the knowledge training of three times or more was higher than that in the people who received the knowledge training of two times or less (χ 2 = 11.439, P = 0.003). The logistic regression showed that the age, educational level, training times and dog raising were the main influencing factors. The related behavior survey showed that 32.7% (260/796) of residents did not drink unboiled water, 37.0% (61/165) of dog owners tied the dog, 43.6% (72/165) of dog owners fed the dogs with anthelmintic regularly, and only 10.3% (17/165) of dog owners buried the dog's dung., Conclusions: The awareness rate of echinococcosis prevention knowledge in Maerkang City should be improved. The health education should be focused on the young people, people with low educational level, and people who have dogs. The behaviors of drinking unboiled water, tying dogs, feeding dogs with anthelmintic regularly, and burying dog' s dung should be advocated.

Objective: To report the integrated progress of the hydatid disease information management system, and to provide the reference for further system improvements by analysis of results on simulation test feedback., Methods: The work of institutional code matching by collecting fundamental and integrated information of the system in epidemic areas of hydatid disease was carried out, and professional control agencies were selected to carry out the simulation test., Results: The results of agencies code matching at stage indicated the average completion rate was 94.30% on administrative agencies, 69.94% on registered professional agencies and 56.40% on professional institutions matching related to hydatid disease prevention and control implements in seven provinces (autonomous regions) and Xinjiang Production and Construction Corps. Meanwhile, the response rate of open-ended proposals was 93.33% on fifteen feedbacks, and the statistics showed 21.43% believed the system was low fluency, 64.29% considered the system was inconvenience for data inputs and 42.86% considered it would be improved on system statistics functions, of which 27.78% were provincial users, 22.22% were the city users and 50.00% were the county users., Conclusions: The hydatid disease prevention information management system meets the fundamental needs of the majority agencies in hyperendemic areas of echinococcosis, it needs to develop the further test with more agencies joining after the work of the institutional code matching completion and the system service improvement in the next stage.

Objective: To understand the situation of prevention and control knowledge of echinococcosis in students in Qinghai Province, so as to provide an evidence for effective prevention and control of echinococcosis., Methods: The students of Grade Four or above were randomly selected with the multi-stage stratified cluster sampling method and investigated with the questionnaire about echinococcosis in Qinghai Province., Results: Totally 23 600 students were selected and surveyed, with the pass rate of 66.0% (15 566 cases). The pass rates of the male and female students were 65.1% (7 947 cases) and 66.9% (7 619 cases) respectively, and the difference was significant ( χ 2 = 8.454, P < 0.01). The difference of pass rates among different districts of Qinghai Province was statistically significant ( χ 2 = 3 848.619, P < 0.01)., Conclusions: The general aware rate of echinococcosis knowledge in students is not high in Qinghai Province, and therefore, it is necessary to enhance the health education, especially for students in pasturing areas.

Objective: To evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease, in which questions existed are summarized in order to promote the system update., Methods: A questionnaire was designed and distributed to Inner Mongolia, Sichuan, Tibet, Gansu, Qinghai, Ningxia, Xinjiang and Xinjiang Production and Construction Corps to evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease assistant with telephone., Results: The recovery rate of questionnaires was 87.5%. The statistics of closed questions showed that national application rate of the China Disease Prevention and Control Information System of Hydatid Disease was 100%, of which 15.3% were low frequency users, 57.1% believed the system was necessary, 28.6% considered it was dispensable, and 14.3% believed that it was totally unnecessary. The statistics of open-ended questions indicated that 6 endemic regions suggested to increase the guidance and training, while 4 endemic regions had opinions on sharing the information of the national infectious disease reporting systems and hydatid disease prevention and control information system, and the opinions on turning monthly report to quarterly report, and increasing statistics and analysis module, and 3 endemic regions deemed that the system had logic errors and defects., Conclusions: The problems of the system are mainly focused on the existence of systemic deficiencies and logic errors, lacking of statistical parameters and corresponding analysis function module, and lacking of the guidance and training, which limits the use of the system. Therefore, these problems should be resolved.

Objective: To investigate the Echinococcus infection of people and domestic animals in Liyang City, so as to provide the evidence for the establishment of control measures of echinococcosis., Methods: The formerly confirmed cases and clue cases were investigated. The Echinococcus antibody in serum of children aged from 7 to 12 years old and adults in key towns and control towns was detected with ELISA, and the antigen in fecal samples of dogs in key towns was also detected. B ultrasound was applied to examine the ELISA positive cases, family member and the neighbored people around them. The sheep in the market were dissected and examined for Echinococcus., Results: The Echinococcus antibody positive rates were 0.93% and 0.52% in children and adults, respectively. The Echinococcus antigen positive rate was 0.95% in dogs. There were no significant difference between the positive rates of the children and adults (CHI2 = 2.124, P > 0.05). No cases were found by ultrasonic examination and no Echinococcus infection was found in the sheep., Conclusion: The people with Echinococcus antibody in serum and dogs with antigen in their feces are found in the surveillance of echinococcosis, therefore, there exists the complete chain of transmission in local. Thus, in the prevention and control work for the disease, the monitoring of dog feces, quarantine of sheep from other regions, as well as the population health education in key areas should be strengthened.
