Dengue is a self limiting acute mosquito transmitted disease characterized by
fever, headache, muscle, joint pains, rash, nausea and vomiting. Dengue Fever
(DF) is caused by an arbovirus and spread by Aedes mosquitoes. Some infections
result in Dengue Haemorrhagic Fever (DHF) and in its severe form Dengue Shock
Syndrome (DSS) can threaten the patientís life primarily through increased vascular
permeability and shock.
Over the past two decades, there has been global increase in the frequency of DF,
DHF and its epidemics, with a concomitant increase in disease incidence. Various
factors responsible for the resurgence of dengue epidemic are: (i) un-precedented
human population growth; (ii) un-planned and un-controlled urbanization; (iii)
inadequate waste management; (iv) water supply mismanagement; (v) increased
distribution and densities of vector mosquitoes; (vi) lack of effective mosquito control
has increased movement & spread of dengue viruses and development of hyper
endemicity and (vii) deterioration in public health infrastructure.
