The research results showed that the 5 communicable diseases with the highest average rate of infection per 100,000 people were diarrhea, hand-foot-mouth disease, dengue fever, varicella and hepatitis. Multivariate regression analysis showed that the increase in dengue was related to changes in climatic factors (temperature, humidity, precipitation) during 2014-2018 in Can Tho City (r = 0.78, p <0.05). We should pay attention to the communicable diseases related to the weather factors in order to prepare the best healthcare resources for epidemics prevention.
