Background: Dengue fever (DF) and dengue hemorrhagic fever (DHF) are important arthropod borne viral diseases. Dengue in India has dramatically expanded over the last few decades, with rapidly changing epidemiology. Dengue is emerging as major public health concern in northeast India and spreading with increased morbidity. Objective: This study was carried out to determine the seroprevalence of...

Dengue is one of the most problematic vector-borne diseases in the Philippines, with an estimated 842,867 cases resulting in medical costs of $345 million U.S. dollars annually. In December 2015, the first dengue vaccine, known as chimeric yellow fever virus-dengue virus tetravalent dengue vaccine, was approved for use in the Philippines and is given to children 9 years of age. To estimate the ...

The aim of this study was to retrospectively determine the prevalence of dengue virus from April 2010 to November 2010 in Brunei Darussalam. A total of 250 serum samples from dengue diagnosed patients were examined. All serum samples were tested for dengue IgM and IgG antibodies and dengue NS1 antigen using the PanBio dengue ELISA commercial kit. To determine the prevalence of dengue virus sero...

Myocarditis is a common complication of severe dengue infection. However, data about prevalence and characterization of myocarditis in dengue are still lacking. In 2014, the worst outbreak of dengue in the last two decades in China occurred. In this study, we described the clinical and laboratory diagnostic features of dengue with myocarditis. Totally, 1782 diagnosed dengue patients were admitt...

BACKGROUND Few studies of dengue have shown group-level associations between demographic, socioeconomic, or geographic characteristics and the spatial distribution of dengue within small urban areas. This study aimed to examine whether specific characteristics of an urban slum community were associated with the risk of dengue disease. METHODOLOGY/PRINCIPAL FINDINGS From 01/2009 to 12/2010, we...

Dengue virus, the causative agent of dengue fever (DF) and more severe forms of the disease – dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS) – can infect a number of different types of cells. While monocytes and macrophages are considered to be primary target cells driving the pathology of the disease, numerous studies have implicated the liver as a site of dengue virus replica...

Dengue is endemic in the U.S. Virgin Islands, but no outbreaks have been reported since 2005. In November 2012, a school nurse in St. Croix reported suspected dengue in 27 (7%) of 369 students and staff members to the Virgin Islands Department of Health (VIDOH) and the CDC Dengue Branch in Puerto Rico. Four of 12 patient specimens sent to the CDC Dengue Branch for diagnostic testing were confir...

BACKGROUND & OBJECTIVE Dengue infection is an arthropod borne disease caused by Dengue virus in humans. Dengue virus infection has more potential to produce severe form of the disease with more severe symptoms. Proper diagnosis of dengue fever is very important for its safe management. The objective of this study was to evaluate the non structural protein-1 (NS1) positive parameter for identifi...

It is known that anti-dengue virus antibodies at subneutralizing concentrations augment dengue virus infection of IgG FcR (Fc gamma R)-positive cells, and this phenomenon is called antibody-dependent enhancement. This is caused by the uptake of dengue virus-antibody complexes by Fc gamma R. We previously reported that Fc gamma RI can mediate antibody-dependent enhancement. In this study we use ...

Dengue outbreak has affected rural areas of Delhi-NCR, Haryana widely but it lacks in surveillance. High cases of dengue symptoms were reported in these regions whereas dengue symptoms have been a neglected issue in the anti-dengue drug development. Therefore, this study aims to analyze the status of the dengue infection, a rural issue of Delhi-NCR, Haryana and to identify the significance of d...
