RESUMO
Objective To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. Methods From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. Results The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. Conclusions Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.
RESUMO
OBJECTIVE: To evaluate the effect of the integrated strategy in prevention and control of intestinal nematodiasis in Hongze County, so as to provide the evidence for formulating the control strategies and measures in the future. METHODS: Since 1995, the integrated strategy has been carried out for intestinal nematodiasis, and the measures included deworming, health education, safe water, sanitation and environmental remediation. The effects of the integrated strategy were evaluated by the investigations of the prevalence of soil-transmitted nematodiasis, awareness of health knowledge and behaviors of residents. RESULTS: From 1995 to 2014, 601 900 person-times were administrated with deworming medication and the coverage rate of villages and towns was 100%. The benefit rate of safe water was 100%. The popularity rate of harmless toilets was 92.77%. The prevalence of intestinal nematodiasis decreased from 26.04% in 1995 to 0.56% in 2014, and the difference had statistical significance (χ2 = 693.54, P < 0.01). The awareness rate of health knowledge and correct rate of health behaviors increased from 43.13% and 40.94% in 1995 to 98.00% and 96.80% in 2012, respectively (χ2 ï¼ 181.97 and 182.14 respectively, Pï¼0.01). CONCLUSIONS: The prevalence of intestinal nematodiasis has been controlled effectively through the integrated strategy in Hongze County, Jiangsu Province.
