Dengue fever in adults and older children appears more frequently than before. Many patients are subjective or do not have information to recognize the signs of dengue fever in adults, making the disease worse and increasing the mortality rate.

Up to now, dengue fever no longer occurs in a certain cycle but appears all year round, greatly affecting the health of the entire community. This is a disease that has no vaccine to prevent, so proactively learning about measures to prevent dengue fever is very necessary.
