[Knowledge, attitude and practice on schistosomiasis control of chronic schistosomiasis patients in Poyang Lake area, Nanchang City].

OBJECTIVE: To understand the present situation of the chronic schistosomiasis patients' knowledge, attitude and practice on schistosomiasis control in Nanchang City. METHODS: The knowledge, attitude and values on schistosomiasis control of 523 chronic schistosomiasis patients in Nanchang County, Jinxian County and Xinjian District in the Poyang Lake District were investigated with questionnaires. And the accuracy rates of the knowledge, attitude and practice among the patient groups of different counties, genders, age groups, occupations and educational levels were analyzed. RESULTS: The accuracy rates of the knowledge, attitude and practice of patients on schistosomiasis control were 95.76%, 82.80%, and 81.73% in Nanchang County; 91.37%, 93.32%, and 76.48% in Jinxian County; 88.25%, 67.56%, and 49.40% in Xinjian District. In the accuracy rates of knowledge, attitude and practice, the differences among the three counties (districts) were statistically significant (χ2 = 57.511-301.378, all P < 0.05) . CONCLUSIONS: The accuracy rates of chronic schistosomiasis patients' attitude and practice on schistosomiasis control in Nanchang City remain low. Therefore, the intensity of attitude and practice intervention should be strengthened in the Poyang Lake District in order to enhance the self-protection awareness of the patients.

[Investigation on human Toxoplasma gondii infections in Nanchang City in 2014].

OBJECTIVE: To investigate the endemic situation of human Toxoplasma gondii infection in Nanchang City in 2014 and analyze the influencing factors, so as to provide the evidence for control measures. METHODS: The high-risk population of T. gondii infection in Nanchang City was collected as an experiment group, and a control group was settled with the ratio of 1∶1. The serum tests and epidemiology surveys were conducted simultaneously, and the influencing factors were analyzed. RESULTS: The total positive rate of human T. gondii was 5.17% (124/2 400) among the whole population in Nanchang City in 2014. The positive rate was 7.50% (90/1 200) in the experiment group and 2.18% (34/1 200) in the control group, and the difference was significant (χ2 =26.668, P＜0.05). The results of univariate analysis indicated that different dietary habits and health habits were closely related to the infection of T. gondii (χ2 =16.522, 64.954, both P＜0.05). The result of Logistic analysis showed that the risk factors of T. gondii infection were occupation, educational levels, raising cats, contacting animals or raw meat, and eating raw or uncooked beef. CONCLUSIONS: The high risk population of T. gondii infection is the key population of the toxoplasmosis control. Unhealthy dietary and living habits are key influencing factors of toxoplasmosis, and the related health education and surveillance work should be strengthened.
