[Effect of comprehensive control in demonstration plots of parasitic diseases in Guizhou Province]

Abstract

Objective: To evaluate the effect of comprehensive control in demonstration plots of parasitic diseases in Guizhou Province.

Methods: The data of parasitic disease control in demonstration plots from 2006 to 2009 were collected and analyzed, including deworming, water and latrines renovation, health education, survey on infections in crowd, etc.

Results: After 3 years comprehensive control, the infection rates of soil-transmitted nematodes among people reduced from 30.25% to 8.37%, with the reduction rate of 72.32%. The infection rates of Ascaris lumbricoides, hookworm and Trichuris trichiura reduced from 26.88%, 2.86% and 4.13% to 7.43%, 0.09% and 1.13%, respectively. The awareness rate of health knowledge among residents increased from 44.18% to 93.64%, with an increasing rate of 111.94%. The coverage rate of non-hazardous sanitary latrines was 81.29%. The beneficial rate of the water renovation reached 96.31%.

Conclusions: The comprehensive control strategies mainly based on health education and infectious source control correspond to the reality of rural parasitic disease control nowadays. The comprehensive control model integrating government leadership, department cooperation and social concern is useful for parasitic disease control and should be popularized.
