Dengue is an acute infectious disease of viral etiology. It is probably one of the most important arthropod borne viral disease in terms of human morbidity and mortality. The spectrum of disease ranges from self-limited dengue fever to more severe forms of dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Laboratory diagnosis of dengue virus infection mainly depends on detection of...

BACKGROUND There is an urgent need to field test dengue vaccines to determine their role in the control of the disease. Our aims were to study dengue epidemiology and prepare the site for a dengue vaccine efficacy trial. METHODS AND FINDINGS We performed a prospective cohort study of children in primary schools in central Thailand from 2006 through 2009. We assessed the epidemiology of dengue...

Animal models of dengue virus disease have been very difficult to develop because of the virus' specificity for infection and replication in certain human cells. We developed a model of dengue fever in immunodeficient mice transplanted with human stem cells from umbilical cord blood. These mice show measurable signs of dengue disease as in humans (fever, viremia, erythema and thrombocytopenia),...

OBJECTIVE The Flavivirus genera share epitopes inducing cross-reactive antibodies leading to great difficulty in differentially diagnosing flaviviral infections. This work was aimed at evaluating the complexity of dengue and yellow fever serological differential diagnosis. MATERIAL AND METHODS Dengue antibody capture ELISA and a yellow fever neutralisation test were carried out on 13 serum sa...

BACKGROUND Each year dengue related infections are rising in tropical countries. There is not enough data available on dermatological manifestations of dengue fever. This study was conducted to investigate prevalence and type of dermatological manifestations of dengue fever (DF). Dengue Haemorrhagic Fever (DHF), and Dengue Shock Syndrome (DSS). METHODS A Prospective study was contacted in Dep...

ing disease caused by dengue virus of Flaviviridae family. It may present as a wide spectrum of manifestations ranging from mild dengue fever to severe forms like dengue haemorrhagic fever (DHF) and dengue shock syndrome. Development of severe form of dengue may be predicted early on the basis of high risk factors like older age, presence of other associated infections, history of dengue fever ...

INTRODUCTION Dengue viral infections are among the most important mosquito-borne diseases of the Indian subcontinent and have become a major global public health concern. Spread of disease has led to increased recognition of atypical manifestations apart from the classical clinical features of dengue infection. METHODOLOGY A cross-sectional study of admitted patients suspected to have dengue ...

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 ...

Both the number of cases of dengue fever and the areas of outbreaks within Nepal have increased significantly in recent years. Further expansion and range shift is expected in the future due to global climate change and other associated factors. However, due to limited spatially-explicit research in Nepal, there is poor understanding about the present spatial distribution patterns of dengue ris...
