Characteristics of Dengue Fever

What are the characteristics of Dengue fever?

The Dengue virus travels to various glands in the body where it multiples. It then travels to the bloodstream, affecting some changes to these blood vessels. The virus may cause the blood vessels to swell and leak. The spleen and lymph nodes may also become swollen. Patches of liver tissue may die. Furthermore, a process known as disseminated intravascular coagulation (DIC) occurs. During this process, chemicals used to clot blood are used up, and thus severe bleeding (hemorrhage) occurs internally as well as the skin.
