Dengue fever is a viral disease that is transmitted by mosquitoes and affects humans. In rare cases, dengue fever can cause visual impairment, which usually occurs within 1 month after contracting dengue fever and ranges from mild blurring of vision to severe blindness. Visual impairment due to dengue fever can be detected through angiography, retinography, optical coherence tomography (OCT) im...

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...

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...

Dengue, a disease caused by group B flavivirus (I), has caused serious epidemics in the Caribbean area and in the tropical countries of Asia and Africa. The virus, of which there are four serotypes (dengue 1, dengue 2, dengue 3, and dengue 4), is transmitted by the Aedes aeg@ti mosquito, which also transmits yellow fever; the mosquito Aedes albopictus also acts as a dengue vector in Southeast A...

Dear Editor, Dengue is an important arbovirus infection. This infection can result in an acute febrile illness. The important hematological abnormalities included hemoconcentration and thrombocytopenia (1). Due to the decreased platelet count, the patient might develop petechiae and hemorrhagic complication. In endemic area, the presumptive diagnosis of dengue is usually derived by the cl...

A virus belonging to the Flaviviridae group causes dengue haemorrhagic fever. Dengue presenting as acute liver failure is rare. Dengue is endemic in India. The last epidemic of dengue occurred in Delhi in 2003. During this epidemic, 2185 confirmed cases of dengue were reported. Dengue virus serotypes 2 and 3 were responsible for this epidemic. A 19-yr-old male presented to our hospital with the...

Background Dengue is a systemic infection with a wide clinical spectrum including asymptomatic, mild undifferentiated dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue with shock syndrome (DSS). Detection of dengue NS1 antigen (Ag) in acute infection is a valuable tool for early diagnosis. The purpose of this study was to evaluate the sensitivity of the Platelia NS1 Ag kit (BioRad®) ...

OBJECTIVE To describe the epidemiology, clinical and laboratory findings, and outcomes of patients presenting locally with dengue. DESIGN Retrospective review of case records. SETTING Public hospitals, Hong Kong. PATIENTS Medical records of all laboratory-confirmed dengue patients admitted to public hospitals during 1998 to 2005 were reviewed retrospectively. RESULTS A total of 126 case...

A previously well 13-year-old boy presented with a short history of fever and altered mental status. His mother was admitted for dengue fever and there had been a recent dengue outbreak in their neighbourhood. He was diagnosed with dengue encephalitis as both his dengue non-structural protein 1 (NS-1) antigen and cerebrospinal fluid (CSF) dengue polymerase chain reaction (PCR) were positive. He...

This study was designated to describe clinical and biological features of patients with a suspected diagnosis of dengue fever/dengue hemorrhagic fever during an outbreak in Central Vietnam. One hundred and twenty-five consecutive patients hospitalized at Khanh Hoa and Binh Thuan Provincial hospitals between November 2001 and January 2002 with a diagnosis of suspected dengue infection were inclu...
