Dengue and Severe Dengue: Dengue is transmitted by the bite of an Aedesmosquito infected with any one of the four dengue viruses (DEN 1, DEN 2, DEN 3 and DEN 4). It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3-14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults. Dengue fever virus (DENV) is an RNA virus of the family Flaviviridae; genus Flavivirus.
Dengue is a mosquito-borne infection found in tropical and sub-tropical regions around the world. In recent years, transmission has increased predominantly in urban and semi-urban areas and has become a major international public health concern.
Severe dengue (previously known as Dengue Haemorrhagic Fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today, severe dengue affects most Asian and Latin American countries and has become a leading cause of hospitalization and death among children in these regions.
