BACKGROUND Dengue, although endemic in Puerto Rico, is often not mentioned in the death certificates of decedents with laboratory results positive for dengue. Because confirmatory results are usually not available during hospitalization, we examined the utility of 2 instruments for diagnosis on the basis of clinical findings: the definition of dengue hemorrhagic fever (DHF) and the publicized (...
BACKGROUND Dengue is a global human public health threat, causing severe morbidity and mortality. The occurrence of sequential infection by more than one serotype of dengue virus (DENV) is a major contributing factor for the induction of Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), two major medical conditions caused by DENV infection. However, there is no specific drug or va...
While dengue virus is thought to replicate in mononuclear phagocytic cells in vivo, attempts to detect it in peripheral blood mononuclear cells (PBMC) by virus isolation or antigen detection have had variable and generally low rates. In this study, we developed a reverse transcription (RT)-real-time PCR assay to quantify positive- and negative-sense RNA of dengue virus type 2 within the cells. ...
Dengue, a mosquito-borne viral illness caused by dengue virus types (DENV)-1 to DENV-4, is endemic in Puerto Rico. Severe dengue usually occurs in individuals previously infected with DENV or among infants born to previously infected mothers. To describe clinical features of dengue in infants, we retrospectively characterized dengue patients aged < 18 months reported to the Passive Dengue Surve...
BACKGROUND Dengue is the most widespread mosquito-borne viral disease of public health concern. In some patients, endothelial cell and platelet dysfunction lead to life-threatening hemorrhagic dengue fever or dengue shock syndrome. Prognostication of disease severity is urgently required to improve patient management. The pathogenesis of severe dengue has not been fully elucidated, and the role...
INTRODUCTION Dengue is a major public health problem in Singapore. Age-specific dengue morbidity rates are highest in the young adult population, unlike in many other Southeast Asian countries where dengue is mainly a paediatric disease. Hence, the World Health Organization (WHO) guidelines on dengue diagnosis and management which were developed using the paediatric experiences, may not be suit...
With 2.5 billion people at risk, dengue is a major emerging disease threat and an escalating public health problem worldwide. Dengue virus causes disease ranging from a self-limiting febrile illness (dengue fever) to the potentially fatal dengue hemorrhagic fever/dengue shock syndrome. Severe dengue disease is associated with sub-protective levels of antibody, which exacerbate disease upon re-i...
Dengue virus remains the most important arbovirus worldwide, and dengue disease poses a significant public health threat. Infection by one dengue serotype does not produce life-long protection against the other three serotypes, and severe disease may be due to non/poorly-neutralizing antibodies to heterologous or homologous dengue serotypes. As such, development, validation, and implementation ...
Objectives: The increasing incidence of dengue fever has become a priority health issue for Sri Lanka. Recent dengue outbreaks in Sri Lanka show two trends: yearly increase of total number of dengue incidence and increasing dengue outbreaks outside the endemic urbanised areas in the south and the west. Identification of factors responsible for dengue outbreaks and the mapping of potential risk ...
Dengue is currently listed as a "neglected tropical disease" (NTD). But is dengue still an NTD or not? Classifying dengue as an NTD may carry advantages, but is it justified? This review considers the criteria for the definition of an NTD, the current diverse lists of NTDs by different stakeholders, and the commonalities and differences of dengue with other NTDs. We also review the current rese...
