In this study, the antidengue virus activity of the ethanol extract from the leaves and twigs of E. cyathophora on four virus serotypes DENV1-DENV4 was examined. The result showed that the ethanol extract displayed antidengue activity on DENV1-4 with PRNT50 values of 15.625-62.5 µg/mL. This extract was fractionated to the n-hexane and ethyl acetate fractions.

The study of human B cell response to dengue virus (DENV) infection is critical to understand serotype-specific protection and the cross-reactive sub-neutralizing response. Whereas the first is beneficial and thus represents the ultimate goal of vaccination, the latter has been implicated in the development of severe disease, which occurs in a small, albeit significant, fraction of secondary DENV infections.

The incidence and geographic range of dengue have increased dramatically in recent decades. Climate change, rapid urbanization and increased global travel have facilitated the spread of both efficient mosquito vectors and the four dengue virus serotypes between population centers.

With more than 300 million potentially infected people every year, and with the expanded habitat of mosquitoes due to climate change, Dengue virus (DENV) cannot be considered anymore only a tropical disease.

Dengue virus serotyping is crucial for clinical management and epidemiology of the disease. As serotype shifts and secondary infection with a heterologous DENV serotype are frequently associated with disease severity, there is a need for sustained monitoring of the circulating serotypes and enhanced surveillance operations to prevent large scale severe dengue outbreaks.

Dengue Fever is a mosquito-borne illness commonly present throughout the tropics. Dengue virus belongs to flaviviridae family and circulates with 4 different serotypes circulating in environment. In India four different serotypes of the virus are seen throughout country. The disease has a wide spectrum from an asymptomatic stage to DHF and DSS. Annually 100 million cases of dengue and a half million cases of DHF occurs worldwide with a case fatality of 0.5% to 3.5%. The combined laboratory interventions with the clinical spectrum can reduce the mortality in disease.

Dengue Fever is a Flaviviral infection transmitted by the Aedes mosquitoes. It is a major public health issue in tropical and subtropical countries. Dengue virus is having four serotypes. It may progress to Dengue Hemorrhagic Fever, which can lead to Dengue Shock Syndrome and death. The study was conducted in the Department of Microbiology. K S. Hegde Medical Academy with the blood samples collected from the patients with clinical diagnoses of Dengue without any age or gender restriction. The samples were collected from the period of October 2015 to April 2017.

Dengue is a viral disease spread to humans by mosquitoes. Notably, there are four serotypes of dengue viruses (DENV) that places ~40 % of the global population at risk of infection. However, lack of a suitable drug or a preventive vaccine exacerbates the matter further.

Four antigenically distinct serotypes (1–4) of dengue viruses (DENVs) cause dengue disease. Antibodies to any one DENV serotype have the potential to predispose an individual to more severe disease upon infection with a different DENV serotype.

Dengue fever is an acute febrile infectious disease, caused by any of four serotypes. Severe dengue infections may give rise to many complications such as liver failure, disseminated intravascular coagulation, encephalopathy, myocarditis, acute renal failure and haemolytic uraemic syndrome. ST segment and T wave changes in the electrocardiogram together with low ejection fraction and global hypokinesia on radionuclide ventriculography have been found. Hence, this study was intended to assess the cardiac manifestations in dengue fever patients.

Dengue is a mosquito borne viral disease (Priyadarshini et al., 2016). It belongs to the family of Flavivirus. It is transmitted mainly by the bite of Aedes aegypti mosquito. Outbreaks are due to the four serotypes DEN1, DEN2, DEN3, DEN4. Increasing incidence and repeated outbreaks turns this disease as a serious public health problem (Barrera et al., 2002). Urbanization, improper water management and the vector population are the main causes for the spread of the disease. Dengue is a leading causes of hospitalization and death among children (Mistry et al., 2013).

Dengue is the most common mosquito-borne viral infection in tropical and sub-tropical countries. Dengue virus, a single stranded positive sense RNA virus belongs to the genus Flavivirus in the family Flaviviridae. Both Aedes aegypti and Aedes albopictus are the main vectors for dengue virus in India. Dengue illnesses are caused by one or more of the serologically related viruses namely DENV-1, DENV-2, DENV-3, DENV-4 and the newly identified DENV-5.India has faced a dramatically expanded dengue virus transmission over the last few decades, with rapidly changing epidemiology.

Dengue is the most important and rapidly spreading mosquito-borne viral disease in the world. It is caused by any of the 4 serologically related virus serotypes designated as: DEN-1, DEN-2, DEN-3 and DEN-4, each causing its characteristic symptoms which range from acute febrile illness to severe manifestations (DHF and DHS). The present study focuses on the circulating serotypes of Dengue in this region. A total of 246 clinically suspected patients of Dengue fulfilling the WHO case definition were undertaken in the study.

Dengue is an important global threat caused by dengue virus (DENV) that records an estimated 390 million infections annually. Despite the availability of CYD-TDV as a commercial vaccine, its long-term efficacy against all four dengue virus serotypes remains unsatisfactory.

Dengue is a re-emerging viral disease, affecting approx. 100 million individ-uals annually. The monoclonal antibody mAb4E11 neutralizes the four serotypes of the dengue virus, but not other flaviviruses. Its epitope is included within the highly immunogenic domain 3 of the envelope glyco-protein E.
