Dengue fever also known as “breakbone fever”, and dengue fever have different names such as Hemorrhagic dengue, Dengue shock Syndrome, Philippine hemorrhagic fever, Thai hemorrhagic fever, Singapore hemorrhagic fever is an infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. Due to the nature of the mosquito-borne infection, dengue has become a significant public health threat in many developing tropical countries. Dengue had been present throughout tropical regions of the world for more than 50 years.At present, due to the efficient mosquito-borne method by which the virus is transported, dengue is not within the tropical region, it also spread in to many nontropical countries. It is accepted that it is now a global issue. In South Asia, there have been many reports of dengue infection in different countries like India, China and also in Pakistan.Dengue infections also extended in Australia rapidly.From 1980 through 1987, 879 632 cases of dengue were reported to the Pan American Health Organization from countries in the American region.From 1981 through 1986, 9774 deaths caused by dengue were reported to the World Health Organization (WHO) from countries in Southeast Asia.

Dengue virus (DENV) belongs to the family Flaviviridae, genus Flavivirus, and is transmitted to humans by Aedes mosquitoes, mainly Aedes aegypti. Based on neutralization assay data, four serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) can be distinguished. Subsequent infection with a different type increases the risk of severe complications. Since 1960s, the incidence of dengue fever has increased with around 50–100 million people infected yearly. Early descriptions of the condition date from 1779, and its viral cause and the transmission were clarified in the early 20th century. Dengue has become a global problem since the Second World War and is spread in more than 110 countries. There is no commercially available vaccine and work is ongoing on a vaccine for Prevention or control of Dengue Fever.
