The cause of the current increase in dengue fever is due to favorable weather conditions for disease-transmitting mosquitoes to develop, especially in the Northern region where hot and humid summer weather conditions, alternating sun and rain create favorable conditions. Favorable for mosquito larvae and disease-carrying mosquitoes to develop, rapid urbanization and travel between regions increase the risk of spread and make it difficult to manage and control disease transmission sources and the environment at construction sites. Construction, factories, factories, motels, and camps are not treated properly, leading to the emergence of larvae (larvae) of disease-transmitting mosquitoes; The initiative and coordination of people and departments and unions in dengue prevention work in some localities is not high.
