Abstract :

The dengue virus is an Arbovirus, belonging to the family Flaviviridae and genus Flavivirus. It is a mosquito borne infection and mostly transmitted by Aedesaegypti and sometimes by A.albopictus. Dengue is caused by four serotypes; DEN-1, DEN-2, 3 and 4. Dengue virus causes a range of illness from a self-limiting classical dengue fever to life threatening dengue hemorrhagic fever and dengue shock syndrome. Dengue is characterized by increased vascular permeability, hypovolemia and abnormal clotting mechanisms^[1].Case fatality rates in endemic countries like India are 2.5%. During dengue epidemics, illness rates among susceptible people are 40-90%. Early recognition and prompt treatment are vital if disease related morbidity and mortality are to be limited^[2]
