目的预测青奥会期间病媒生物危害及其相关疾病发生的风险,以采取有效应对措施,降低其危害,避免媒介生物性传染病的发生或流行。方法通过综合分析风险发生的概率和后果,形成风险列表;然后通过风险评价指数矩阵法综合判断风险的严重程度。结果青奥会期间存在媒介生物性传染病发生和病媒生物骚扰的风险。媒介生物性传染病发生和影响观瞻、环境卫生的风险较低,咬坏电缆、破坏电力设施的事件,污染食品事件风险中等,叮咬、骚扰以及影响开闭幕式效果风险较高。结论通过科学地识别和评估病媒生物可能带来的危害风险,采用系统监测、科学防治、应急储备等措施,确保青奥会无重大病媒生物危害事件发生。 Objective To predict the risk of vector biohazard and its related diseases during the Youth Olympic Games to take effective countermeasures to reduce its harm and prevent the occurrence or epidemic of vector borne diseases. The method forms a risk list by synthetically analyzing the probability and consequence of the occurrence of the risk, and then judges the severity of the risk synthetically through the risk evaluation index matrix method. Results There was a risk of vector-borne diseases and vector-borne diseases during the Youth Olympic Games. The incidence and impact of biological infectious diseases are low, the risk of environmental sanitation is low, the risk of biting cables, destroying power facilities, medium risk of contamination of foodstuff incidents, bites, harassment and affecting the opening and closing ceremonies is relatively high. Conclusions By systematically identifying and assessing the possible risks of vector organisms, we adopted systematic monitoring, scientific prevention and treatment and contingency reserve measures to ensure that no major vector biohazard events occurred during the Youth Olympic Games.
