What is Dengue Fever? Breakbone fever, another name for dengue, says it all with its built-in description of a major symptom: joint and muscle pain so severe it causes contortions in many victims. A mosquito-borne viral illness, [1]dengue fever often begins with a severe headache and fever, then blossoms into that severe pain accompanied by vomiting, swollen glands and a rash. About 40 percent of the world's population lives in areas where dengue infection is a risk. Starting in the 1960s with the growing popularity of far-flung leisure travel, dengue has become a global health concern because many popular destinations such as the Caribbean and Puerto Rico, Central and South America, Southeast Asia, and the Pacific Islands are within its realm. In the United States, it has spread infrequently with local outbreaks in Florida, Texas and Hawaii. References 1. https://www.cdc.gov/dengue/index.html .
