Abstract: Malaria had a wide distribution and high prevalence throughout the Three Gorges region of the Yangtze River. After antimalarial program, its incidence rate was reduced to 2.2‰。 in 1985, but sporadic cases still occurred in 34.7% of the townships and local outbreaks were not uncommon. Therefore, potential factors of malaria outbreak are still present.It is predicted that maximum risk of malaria outbreak will take place, during con-struction and after the completion of the reservior, the breeding sites of Anopheles would be extended to irrigation network, low-lying of flooded land, and malaria preva-lence might be increased.
