Objective To assess the risk of vector hazards and vector-borne diseases during the 11th National Traditional Games of Ethnic Minorities in China in 2019, and to take effective measures to reduce such hazards and avoid the occurrence and prevalence of vector-borne diseases. Methods A risk list was formed by analyzing the probability of risk events and the consequence of games events, and the severity of the risk was determined using the risk evaluation index matrix method. Results In the central and surrounding core zones of Zhengzhou Olympic Sports Center, the mosquito density based on mosquito lamp trap was 13.75 mosquitoes/lamp·night, the fly density based on fly trap cage was 21.20 flies/per cage, and the positive rate of indoor rodent tracks was 7.08%, while no cockroaches were found. There was a risk of vector-borne diseases and vector-borne harassment during the Games in September 2019. Vector-borne diseases had a low risk of affecting appearance and environmental health, a moderate risk of destroying electric power facilities and inducing food poisoning, and a high risk of causing sting and harassment and affecting the opening and closing ceremonies of the Games. Conclusion The measures including scientific identification and evaluation of the risk of hazards brought by vectors, systematic monitoring, scientific prevention and control, and emergency preparedness were adopted to ensure that no major hazardous events caused by vectors occurred during the Games.
