Abstract

Abstract:

The preliminary goal of echinococcosis control in the national 13th five-year plan is to reduce the human prevalence to < 1% and dog infection rate to < 5% in 70% of all endemic counties by 2020. By 2019, 83% of the counties in Sichuan Province had reached the goal, overfulling the national control plan. The control of echinococcosis in Sichuan Province has gone through four stages: the key investigation and research stage, the pilot stage carried out mainly by the health department, the preliminary stage for coordinated control by related departments, and the stage of achieving preliminary control led by the government. Great achievements have been gained in echinococcosis control, from prevalence to preliminary control, demonstrating the significant effectiveness of the comprehensive control strategy of “controling the source of infection as the main strategy, intermediate host control combining with patient screen and treatment”. The success of echinococcosis control in Sichuan Province can be attributed to the strategy of “cooperation of party and government, and population-based mobilization”, the cooperation among departments, scientific control measures, and the support from professional teams; to the continuous exploration of new strategies and measures, such as seasonal strengthening of dog deworming, rodent control in settlements, as well as the innovation of patient screening and management, health education, and monitoring of transmitting hosts. In the future, we should keep exercising the strategies and measures that proved effective in practice, and optimize strategies and measures in response to new epidemic situations timely to achieve accurate control and further control of echinococcosis transmission.
