We report a 49-year-old diabetic with dengue hemorrhagic fever who developed fulminant hepatitis, severe coagulopathy, shock, and refractory metabolic acidosis and died on the eighth day of illness. This is the only second report of an adult with fatal fulminant hepatic failure due to dengue, and the first case arising from a primary dengue infection.

The ongoing resurgence of Aedes aegypti in the Americas--abetted by poor mosquito control, urbanization, and increased air travel--has led to dengue hyperendemicity, more frequent dengue epidemics, and the emergence of dengue hemorrhagic fever (DHF). This article describes a program developed to cope with this situation that emphasizes disease prevention rather than general mosquito control mea...

The pre-membrane (prM) and envelope (E) genes of 41 viruses isolated from dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) patients from 1995 to 2002 were sequenced to determine the genetic variability of dengue 2 (DENV 2) viruses in the Philippines. The envelope sequence data were compared with a global sample of DENV 2 obtained from GenBank. Phylogenetic anal...

Dengue virus (DENV) circulates in human and sylvatic cycles. Sylvatic strains are both ecologically and evolutionarily distinct from endemic viruses. Although sylvatic dengue cycles occur in West African countries and Malaysia, only a few cases of mild human disease caused by sylvatic strains and one single case of dengue hemorrhagic fever in Malaysia have been reported. Here we report a case o...

A case of vertical transmission of dengue infection in the perinatal period is reported. The mother, a term pregnancy, had acute dengue the day before admission. The infant was born at term and developed fever on the fifth day of life which lasted for 5 days. No bleeding or plasma leakage was detected during the course of fever in infant or mother. A liver function test showed elevated SGOT and...

The major arboviral diseases in mainland China include Japanese encephalitis, dengue fever, Crimean-Congo hemorrhagic fever (also known as Xinjiang hemorrhagic fever), and tick-borne encephalitis. These and other newly found arbovirus infections due to Banna virus and Tahyna virus contribute to a large and relatively neglected disease burden in China. Here we briefly review the literature regar...

The World Health Organization (WHO) has coined the term expanded dengue to describe cases which do not fall into either dengue shock syndrome or dengue hemorrhagic fever. This has incorporated several atypical findings of dengue. Dengue virus has not been enlisted as a common etiological agent in several conditions like encephalitis, Guillain Barre syndrome. Moreover it is a great mimic of co-e...

Dengue hemorrhagic fever or DHF is an infectious disease caused by the dengue virus and characterized thrombocytopenia. Thrombocytopenia that persists in can cause life-threatening complications. Monitoring platelet count, addition to hematocrit level, important determine severity of DHF. Therapy for currently focuses on supportive symptomatic therapy. Alternative therapy using guava (Psidium g...

The Dengue virus is an arbovirus, from genus Flavivirus family Flaviviridae. It is a single stranded RNA genome surrounded by an icosahedral nucleocapsid and covered by lipid envelope. Four serotypes: DEN-1, 2, 3, 4 have been identified for the virus. Each serotype provides specific lifetime immunity, but only a shortterm cross-immunity. All serotypes can cause severe and fatal disease. In the ...

Prolonged thrombocytopenia in a usual case of dengue virus infection is uncommon. Dengue-related thrombocytopenia is self-limiting and responds within 3-5 days. An underlying immunological disorder may be responsible for delayed return of platelet count to a normal level. We present a case of prolonged thrombocytopenia in a case of dengue hemorrhagic fever. The response to steroids suggests a p...
