[Evaluation on intervention measures of comprehensive control for parasitic diseases in demonstration plot of Xiangyun County].

OBJECTIVE

To evaluate the effect of comprehensive intervention measures to control and prevent parasitic diseases in the demonstration plot of Xiangyun County, so as to provide the evidence for establishing appropriate measures of parasitic diseases control and prevention.

METHODS

The baseline data of soil-transmitted nematode infections were obtained in 2006. A series of intervention measures, including health education, deworming, drinking water improvement,latrine improvement, and environment reconstruction, were performed for three years and the effect of the comprehensive intervention measures was evaluated by the national expert group in 2009.

RESULTS

The awareness rate of parasitic disease knowledge of residents in 2009 (86.96%) was significantly higher than that in 2006 (35.20%) (Chi2 = 122.95, P < 0.01). The passing rate of resident health behavior in 2009 (97.10%) was significantly higher than that in 2006 (48.00%) (Chi2 = 122.95, P < 0.01). The general infection rate of parasites in 2009 (2.47%) was significantly lower than that in 2006 (19.14%) (Chi2 = 162.88, P < 0.01). Of soil-transmitted nematode infections, the infection rates of Ascaris lumbricoides in both 2006 and 2009 were the highest and the rates were 18.74% and 2.08%, respectively.

CONCLUSIONS

In the demonstration plots for parasitic diseases control and prevention of Xiangyun County, the effect of the comprehensive intervention measures which take health education as the forerunner and give priority to control source of parasite infection is remarkable. The measures implemented can achieve the purpose to reduce the infection rates of parasites and improve human health.
