The World Health Organization (WHO) scheme for classification of dengue severity was evaluated in a three-year study of 1,671 confirmed dengue cases in three Nicaraguan hospitals. The WHO classification of dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) was compared with the presence of hemorrhagic manifestations, signs of vascular permeability, marked thrombocytopenia, and shock...

Dengue fever is caused by any of the four serotypes of the dengue virus. Patients with previous dengue infection of one serotype are at risk to secondary dengue infection due to another serotype. In endemic areas, there is a cocirculation of several different dengue serotypes and a high prevalence of dengue antibodies in the population 3. This favours the occurrence of secondary dengue infectio...

We present a rare case of a patient diagnosed with probable dengue fever sustaining an intracranial haemorrhage after a trivial motor vehicle accident. From the literature reviewed, it was noted that there have been no reports of dengue fever presenting with an intracranial haemorrhage, and the association is more common in patients diagnosed with dengue hemorrhagic fever and/or dengue shock sy...

Dengue hemorrhagic fever (DHF) is a severe febrile disease, characterized by abnormalities in hemostasis and increased vascular permeability, which in some cases results in hypovolemic shock syndrome and in dengue shock syndrome. The clinical features of DHF include plasma leakage, bleeding tendency and liver involvement. We studied the histopathological features of a fatal case of dengue-3 vir...

India An outbreak of dengue hemorrhagic fever/dengue shock syndrome (DHS/DSS) occurred in 1996 in India in and near Delhi. The cause was confirmed as dengue virus type 2, by virus cultivation and indirect immunofluorescence with type-specific monoclonal antibodies. This is the largest such outbreak reported from India, indicating a serious resurgence of dengue virus infection.

An urban epidemic of dengue in Senegal during 2009 affected 196 persons and included 5 cases of dengue hemorrhagic fever and 1 fatal case of dengue shock syndrome. Dengue virus serotype 3 was identified from all patients, and Aedes aegypti mosquitoes were identified as the primary vector of the virus.

Dengue fever, dengue hemorrhagic fever and dengue shock syndrome are the prevalent mosquito borne viral infections worldwide. The dengue virus belongs to the genus flavivirus with conserved RNA domains peptidase_S7 and dexHc among its members. The secondary structures for RNA domains peptidase_S7 and DexHc are hence predicted and discussed with other known viral RNA structures to glean structur...

Dengue fever is a potentially life-threatening vector-borne tropical disease caused by a single-stranded positive-sense ribonucleic acid virus belonging to the Flaviviridae family. Outbreaks have increased in severity over the past few years, especially in developing countries in South Asia[1]. While dengue fever is a self-limiting illness in the majority of patients, about 0.5% of patients dev...

Dengue is an infectious disease caused by the dengue virus (DV), which can progress to dengue hemorrhagic fever and dengue shock syndrome. DV causes the production of auto-antibodies against human cells. A variety of factors have been associated with macrophage activation syndrome, including infections, drugs and autoimmune pathologies (systemic lupus erythematosus, systemic onset juvenile idio...

Dengue fever is a mosquito-borne arthropod-borne viral (arboviral) tropical disease in humans affecting 50-528 million people worldwide. The acute abdominal complications of dengue fever are acute appendicitis, acute pancreatitis, acute acalculous cholecystitis and non-specific peritonitis. Acute pancreatitis with new onset diabetes in dengue shock syndrome (DSS) is very rarely reported. We des...
