Dengue Fever: is an infectious disease, which it is caused by tiny pathogenic (harmful) organisms that can be contagious by spreading among people upon contact with an infected person. (Tirtha Chakraborty, 2008) “Dengue is the most common and widespread arthropod-borne viral infection in the world.” (World Health Organization, 2008) The mosquito Aedes aegypti, who feed during the day are the transmitters of the virus. They are found in the tropic areas and Africa. The disease is caused by four closeley related but distinct types of serotype viruses named dengue virus 1(DEN-1), dengue virus2 ( DEN-2), dengue virus 3 (DEN-3), and dengue virus 4 (DEN-4) named by Albert Sabin in 1944. (World Health Organization, 2008) Dengue virsus are small, spherical single-stranded RNA viruses with an evelope from the family Flavividae.

The term “dengue” origins are not clear but some say it is from the Swahili phrase “ka-dinga pepo”, which is described as evil spirit. The first recorded potential case of dengue is in a Chinese medical encyclopedia from Jin Dynasty (265-420 AD). The Chinese stated it was a water poison due to flying insects. (Wikipedia, 2007) The first bona fide cases of dengue were recorded in 1779 in Batavia, Indonesia and in Cairo, Egypt. In 1780, the first definitive case was reported by Dr. Benjamin Rush, he termed the disease as “break bone fever” because of his patient symptoms of Myalgia and Arthralgia.

Is classified with the most feared of all viral diseases. (Tirtha Chakraborty, 2008) Dengue hemorrhagic fever (DHF) can cause trauma or worse, fatalilty. DHF happens when a host is reinfected with the viruse. DHF effects most parts of the body as a multisystem syndrome. The vascular system is damaged and can not recopurate itself. There are still Dengue epidemics occurring today. Last year on December 1, 2008 an outbreak occurred in Carins on Queensland, Australia. As of March 2009 there were...
