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 prevalent among Malaysia's indigenous peoples, known as the Orang Asli, and it poses a serious health threat to them. The study aims to look at the socio-demographic factors, health beliefs, and knowledge about dengue and its association to dengue prevention practices among Orang Asli communities in Peninsular Malaysia. METHODS A cross-sectional survey was conducted in 16...

Two distinct syndromes associated with dengue virus infection are prevalent in tropical Asia; dengue fever, a benign disease characterized by fever, myalgia, leucopenia and a maculo-papular rash and dengue hemorrhagic fever (DHF), accompanied by fever, shock, hemorrhagic diathesis and a significant mortality.1 The dengue viruses, a group of antigenically related members of the Group B arthropod...

Dengue Dengue virus (DENV) belonging to the family Flaviviridae consists of 4 serotypes (DEN-1, 2, 3 & 4) causing severe illnesses like dengue fever (DF), Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Dengue fever has become an emerging disease in Pakistan during the past 5-7 years with an increase in the number of cases every year since 2006. The current study aimed at identi...

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...

Dengue is an infectious mosquito-borne viral disease. Dengue or dengue-like epidemics ranks highly among new and newly emerging infectious diseases in public health significance and may affect persons of all ages in dengue endemic area. Dengue virus infections Montip Tiensuwan and Timothy O’Brien 2 may lead to dengue fever (DF), dengue haemorrhagic fever (DHF) and may lead to hypovolaemic shock...

BACKGROUND Travelers who acquire dengue infection are often routes for virus transmission to other regions. Nevertheless, the interplay between infected travelers, climate, vectors, and indigenous dengue incidence remains unclear. The role of foreign-origin cases on local dengue epidemics thus has been largely neglected by research. This study investigated the effect of both imported dengue and...

There is insufficient evidence of the usefulness of dengue diagnostic tests under routine conditions. We sought to analyse how physicians are using dengue diagnostics to inform research and development. Subjects attending 14 health institutions in an endemic area of Colombia with either a clinical diagnosis of dengue or for whom a dengue test was ordered were included in the study. Patterns of ...

OBJECTIVE Dengue is a worldwide public health problem with approximately 50 million cases reported annually. The World Health Organization proposed a revised classification system in 2008 to more effectively identify the patients who are at increased risk of complications from dengue. Few studies have validated this new classification system in clinical practice. We conducted a cross-sectional ...

Nearly a third of the human population is at risk of infection with the four serotypes of dengue viruses, and it is estimated that more than 100 million infections occur each year. A licensed vaccine for dengue viruses has become a global health priority. A major challenge to developing a dengue vaccine is the necessity to produce fairly uniform protective immune responses to all four dengue vi...
