Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitos. It is an acute illness of sudden onset that usually follows a benign course with symptoms such as headache, fever, exhaustion, severe muscle and joint pain, swollen glands (lymphadenopathy), and rash. The presence (the "dengue triad") of fever, rash, and headache (and other pains) is particularly characteristic of dengue. Other signs of dengue fever include bleeding gums, severe pain behind the eyes, and red palms and soles.
Dengue fever is the most common cause of fever in travelers returning from the Caribbean, Central America, and South Central Asia. Dengue infections are commonly reported from most tropical countries of the South Pacific, Asia, the Caribbean, the Americas, and Africa. This disease is spread through the bites of infected mosquitos. Dengue fever cases has been on the rise in the United States since 2005. An outbreak of Dengue fever has been found in Key West, Florida in both 2009 and 2010 with over 70 reported cases of the disease found among the town’s residents.
