Dengue Virus (DENV), a flavivirus spread by mosquito vectors, can cause vascular leakage and hemorrhaging. However, the processes that underlie increased vascular permeability and pathological plasma leakage during viral hemorrhagic fevers are largely unknown. Mast cells (MCs) are activated in vivo during DENV infection, and we show that this elevates systemic levels of their vasoactive product...

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...

Dengue infection, one of the most devastating mosquito-borne viral diseases in humans, is now a significant problem in several tropical countries. The disease, caused by the four dengue virus serotypes, ranges from asymptomatic infection to undifferentiated fever, dengue fever (DF), and severe dengue hemorrhagic fever (DHF) with or without shock. DHF is characterized by fever, bleeding diathesi...

The number of cases and severity of disease associated with dengue infection in Sri Lanka has been increasing since 1989, when the first epidemic of dengue hemorrhagic fever was recorded. We identified a new dengue virus 1 strain circulating in Sri Lanka that coincided with the 2009 dengue epidemic.

An urban epidemic of dengue in Senegal during 2009 affected 196 persons and included 5 cases of dengue hemorrhagic fever and 1 fatal case of dengue shock syndrome. Dengue virus serotype 3 was identified from all patients, and Aedes aegypti mosquitoes were identified as the primary vector of the virus.

Dengue (pronounced as 'Dhen Gey') is a mosquito borne febrile viral illness. Since its first recognition during the last quarter of eighteenth century, periodic outbreak has been reported from both developed and developing countries with Asia always remaining the area of highest endemicity Until the middle of 20th century dengue was regarded as self-limited, non-fatal febrile illness with occas...

From 2005 to 2013, there were 15 dengue patients aged over 60 years old who were admitted to Photharam Hospital, Ratchaburi, Thailand. Ten were females and five were males. Nine had dengue fever (DF), and 6 had dengue hemorrhagic fever (DHF). A trending shift in age group towards adults has been seen during the past decades. No deaths were seen in these elderly patients with dengue disease, ind...

OBJECTIVE Describing the relationship between viral serotypes, infection pattern and dengue hemorrhagic fever. METHODS 1,545 febrile patients were studied from 1998-2004 in the Santander department of Colombia. Dengue infection was confirmed by IgM ELISA and the virus was isolated in C6/36 cells. Infection pattern was established by detecting IgG antibodies in acute serum. Neutralising antibo...

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...
