RESUMEN
@#Abstract: Objective To evaluate the completion and final effect of key parasitic disease prevention and control planning tasks in Hubei Province from 2016 to 2019, summarize the experience, find out the problems, and provide the basis for the next stage of prevention and control. Methods According to the requirements of the Final Evaluation Plan of the National Plan for the Prevention and Control of Hydatid Disease and Other Major Parasitic Diseases (2016-2020), a retrospective survey method was adopted to collect relevant data on the implementation and safeguard measures of the prevention and control of major parasitic diseases, and population infection status in Hubei Province in 2016-2019. Results From 2016 to 2019, We carried out 2 920 992 person times of publicity and education, 209 times of prevention and control technology training, 7 680 person times of business training, with an average of 52 sessions and 1 920 person times per year. We have allocated 3.445 2 million yuan for the prevention and control of parasitic diseases, including 1.722 2 million Yuan froom provincial government, to achieved full coverage of safe drinking water in rural areas under the current national standards, and 7.687 9 million harmless toilets have been built in rural areas. From 2016 to 2019, we carried out 39 658 person times of monitoring and disease investigation, the infection rate of human liver fluke was 0, and the infection rate of soil transmitted nematode was 0.42%. While the annual infection rates varied, there was no statistically significant difference in infection rate between years (χ2＝2.276, P>0.05), but there were statistically significant differences in the infection rates between various soil nematodes (χ2=112.807, P<0.01). From 2016 to 2019, a total of 5 393 people were detected at 17 monitoring points, with the serum positive rate of 3.93% for paragonimiasis, there was a statistically significant difference in serological positive rate between years (χ2=146.011, P<0.01); a total of 738 stream crabs were collected, and the infection rate of intermediate host was 16.26%, wtih a statistically significant difference in the infection rate of stream crabs between years (χ2=49.731, P<0.01). Conclusions From 2016 to 2019, we adhered to the prevention and control strategy of "prevention first, prevention and control combined", implemented comprehensively various prevention and control measures, and achieved remarkable results in Hubei Province. The key parasitic diseases have been in a low epidemic situation, meeting the requirements of the prevention and control objectives. But the transmission risk still exists, the next step is to continue to strengthen security and monitoring and consolidate the achievements of prevention and control.
RESUMEN
Objective To assess the construction quality of sanitary latrines in schistosomiasis endemic areas of China. Methods Two counties per province were sampled randomly from total 7 provinces with schistosomiasis endemic including Hunan, Hu-bei, Jiangxi, Anhui, Jiangsu, Yunnan and Sichuan, then 2 villages with schistosomiasis endemic were selected from each target county as research sites, and 30 households per village were randomly selected as respondents. Results Among the sanitary latrines being constructed and on-going used in schistosomiasis endemic areas, 64.8% of them were built indoor or inside of yards, and 52.6% of the above household latrines were constructed keeping away from water sources beyond 10 meters. In addition, the latrines with curb height of feces outlet over 100 mm accounted for 75.0% , and 96.1% of the total sanitary latrines were equipped with urinals made of pottery, plastic and cement. There were 98.2% of the latrines with an area more than 1.2 m~2, and 95.8% with structure of the whole room. Among those sanitary latrines with three-case-cesspools, merely 23.1% reached or closed to the design and implementation requirements of Technical criterion of sanitary construction in schistosomiasis endemic areas (protocol) on the part of underground. Conclusions The sanitary latrine with three-case-cesspools and three-unit methane pool is the main type of the household latrine recommended in countryside in schistosomiasis endemic areas. The construction of sanitary latrines meet the requirements of relevant standards in general, however, the design and implementation of underground parts of the latrines with three-case-cesspools need to be improved.
RESUMEN
Objectives To understand the demand,payment capability and influencing factors of sanitary latrine construction in schistosomiasis epidemic areas in China. Methods In Hu’nan,Hubei,Anhui,Jiangxi,Yunnan,Sichuan and Jiangsu,2 counties in each province were selected and 3 villages with schistosomiasis prevalence in each county were randomly sampled. Thirty households were randomly sampled from each village for questionnaire survey. Results The major reasons for constructing sanitary latrine were cleanliness,sanitation and convenience in the rural areas;more than 98% of the households were willing to pay part of the construction,among them,the majority of the families hoped the payment kept within 100-500 yuan (RMB);the problem for the non-sanitary latrine users to construct sanitary ones by themselves was lack of money,technique and skilled labors etc;the residents with the knowledge of rural water supply and latrine improvement,eliminating,keeping livestock enclosure were willing to pay for the construction of sanitary latrine. Conclusion The families using non-sanitary latrine have strong will for constructing the sanitary ones,and they also have payment will and capability to some extents. Most families can afford to the latrine construction within 500 yuan (RMB);to strengthen health education and communication can promote the demand and payment will for construction of sanitary latrine among the people using non-sanitary latrine in schistosomiasis epidemic areas.
