Objective To explore the pathogenesis of cholera and provide the basis for its control. Methods The population of cholera-prone areas were selected and sampled by routine methods for submission to the hospital and based on the reported epidemic situation. Results 83.69% of the patients were located in the wet season. 99.6% of patients are located in the coastal areas, 80.8% of the northwest. Dominant infection and latent infection ratio of 1:17 serious environmental pollution, resulting in pigs, duck with EVC, is the formation of cholera “scattered occurs, the source unknown” reason. Food is the main way to spread cholera. Conclusions The epidemic factors of cholera are complex, and comprehensive measures should be taken to control them. Health education should be provided regularly to the population, especially primary and secondary school students.
