[Final evaluation of medium- and long-term program of schistosomiasis control in Baise City].

OBJECTIVE: To evaluate the monitoring results of medium- and long-term program of schistosomiasis control in Baise City, so as to provide the reference for the elimination of schistosomiasis. METHODS: The data of schistosomiasis control in Baise City from 2004 to 2015 were collected and analyzed. RESULTS: By the end of 2015, the total number of regular screening serum tests for schistosomiasis in the planning period was 10 244 person-times, with 649 positive cases. The number of feces tests was 2 158 person-times in the permanent resident population, and the number was 2 683 person-times in the floating population. The Oncomelania hupensis snail survey area was 150.04 hm2, and the accumulated snail control area was 2.03 hm2. No schistosomiasis patients or schistosome-infected snails were found. CONCLUSIONS: The effect of medium- and long-term program of schistosomiasis control is effective in Baise City, and the criterion of schistosomiasis elimination has been achieved.

[Retrospective analysis of schistosomiasis elimination history in Jingxi City, Guangxi Zhuang Autonomous Region].

OBJECTIVE: To understand the schistosomiasis epidemic and control history in Jingxi City, so as to provide the evidence for improving the future work. METHODS: The data of schistosomiasis prevention and control work were collected and analyzed comprehensively in Jingxi City from 1956-2015. RESULTS: From 1956, the schistosomiasis prevention and control work carried out, and in 1985, Jingxi City reached the standard of schistosomiasis transmission interrupted and no local schistosome infected residents and livestock were found for 36 years. In May 2016, the city reached the national standard of Schistosomiasis Elimination Assessment Review. The cumulative number of schistosomiasis detection of residents was 348 801 person-times, and 10 434 schistosomiasis patients were found. The cumulative number of schistosomiasis detection of cattle was 20 674 head-times, and 590 schistosome infected cattle were found. The cumulative schistosomiasis treatment number of residents was 18739 person-times, and 512 cattle were treated. The cumulative detection area with Oncomelania hupensis was 65 213.25 hm2, and 353.80 hm2 area with O. hupensis snails was found. CONCLUSIONS: Jingxi City has reached the standard of schistosomiasis elimination, but there is still recurrence of O. hupensis snails, and the imported infection source exists. Therefore, we should strengthen the monitoring of floating population.

[Investigation of a case of foreign imported falciparum malaria in Xilin County, Baise City].

OBJECTIVE: To investigate the epidemiology, diagnosis and treatment of an imported falciparum malaria patient in Xilin County, Baise City, so as to provide the reference for improving the diagnosis and treatment of falciparum malaria patients in the future. METHODS: The epidemiological and clinical data were collected and analyzed. RESULTS: The patient had lived in Africa where the malaria was epidemic. The disease attacked him after his coming back home from abroad. The blood test for Plasmodium falciparum was positive. In Xilin County, no local Plasmodium infection was found from 2004 to 2016, and therefore, we concluded that this case was overseas imported. CONCLUSIONS: The monitoring of overseas returnees in Xilin County should be strengthened to timely diagnose and treat the imported cases of malaria.

[Examination and evaluation on malaria elimination in Baise City].

OBJECTIVE: To analyze the assessment results and summary the work experience of malaria elimination in Baise City. METHODS: According to The malaria elimination evaluation schemes of Guangxi (2014 edition), the examination and evaluation of malaria elimination were carried out and all the results were analyzed in 12 counties (county-level city or district) of Baise City from 2014 to 2015. RESULTS: Since 2009, there were no local malaria cases and imported secondary cases in Baise City for the 6 consecutive years, and the detailed data were collected and the self-assessment reports of malaria elimination were written in all the counties. There was no omission or delay of malaria case reports in the 12 counties. The highest score of the examination and evaluation was 96.58 points, the lowest was 90.76 points, and the average was 93.77 points. The biggest impact on the evaluation scores was "on-site examination". CONCLUSIONS: All the 12 counties (county-level city or district) of Baise City have passed the municipal examination and evaluation of malaria elimination, and the key of next work is malaria monitoring, timely finding and treating the imported malaria patients, and to guarantee no imported secondary cases.

[Analysis of malaria epidemic situation in Pingguo County, Guangxi Zhuang Autonomous Region from 1951 to 2014].

OBJECTIVE: To explore the law and distribution characteristics of malaria prevalence in Pingguo County, Guangxi Zhuang Autonomous Region, so as to provide the evidence for formulating the targeted control strategy and measures after malaria elimination. METHODS: The data of malaria epidemic situation in Pingguo County from 1951 to 2014 were collected and analyzed with the retrospective epidemiological method. RESULTS: From 1951 to 2014, there were 71 365 malaria cases reported in the county. The malaria incidence dropped from 429.43/10 000 in 1960 to 0 in 1993. Since 2002, there was no local endogenous infection case reported. In 1993, this county achieved the standard of malaria elimination basically, and in 2014, passed the examination and evaluation of malaria elimination. CONCLUSIONS: In Pingguo County, the comprehensive malarial control strategy is effective in different stages. In the future, the monitoring of mobile population and dealing with imported malaria cases timely is the key of consolidation of malaria control achievements.

Surveillance of key parasitic diseases in Baise City from 2006 to 2015 / 中国血吸虫病防治杂志

Objective To understand and master the infection status of key parasitic diseases in Baise City from 2006 to 2015, so as to provide evidence for the development and adjustment of the control strategy for parasitic diseases. Methods The relevant information of the final evaluation of the key parasitic diseases in 12 counties (cities and districts) of Baise City from 2006 to 2015 was collected, and analyzed. Results During the period of 2006-2015, a total of 20 654 person-times were investigated for parasitic diseases in Baise City and 1 147 persons were infected, with an average infection rate of 5.55%. In 2006, the infection rate was the highest (28.67%, 362/1 254), while the lowest was in 2013 (2.08%, 44/2 113). The infection rate of Clonorchis sinensis was the highest, and the infection rate of Ascaris lumbricoides was the second. The infection rates of the males and females were 5.35% (631/11 795) and 5.82% (516/8 859) respectively, with no significant difference between them (χ2 = 2.175, P > 0.05). The highest infection rate existed in the 40-49 years group, the rural residents, the farmers and the crowd with the educational level of senior high middle school or above. Conclusions The infection rate of parasitic diseases presents a decline trend overall in Baise City from 2006 to 2013, however it rebounded in 2014 and 2015. The next step is to strengthen the prevention and control of parasitic diseases by promoting health education, regular insect repellent, and fecundity management.
