Es gibt vier unterschiedliche Dengue-Virus-Typen 1 2 4 5 und nach einer durchgemachten Dengue besteht nur wenige Wochen bis Monate eine Kreuzimmunität. A retrospective serological study 2008-2015 was conducted on hantavirus and dengue patient sera confirmed by IgM and IgG ELISA NS1 and RT-PCR using Limulus.

Hantavirus and dengue virus. Dengue viruses DENVs and hantaviruses are global health threats accounting for 584 million annual dengue cases and as many as 02 million annual hantavirus infections respectively 12. With both dengue and hantavirus infection the role of the vector is important namely the mosquito primarily Aedes aegypti and rodents Muridinae family eg rats and mice respectively. In 58 of the total 118 patients recent dengue virus infection was serologically confirmed.
In 20 of the remaining 60 patients we found serological evidence of another recent infection. Hantavirus 5 chikungunya virus 2 R. Tsutsugamuchi 2 rubella virus 3 influenza A virus 1 and leptospira 2.
No evidence for recent infection with any of the mentioned. Hantavirus and dengue virus DENV infections are caused by RNA viruses which infect immune systems cells including monocytes macrophages and dendritic cells and occur year-round in Barbados. A retrospective serological study 2008-2015 was conducted on hantavirus and dengue patient sera confirmed by IgM and IgG ELISA NS1 and RT-PCR using Limulus.

Perhaps as a result of some common pathophysiological pathways symptoms of dengue haemorrhagic fever and hantavirus can be very similar.
Together with varying degrees of acute renal failure Asian hantavirus infections and dengue haemorrhagic fever are both characterised by haemorrhagic symptoms thrombocytopenia and a general vascular-leak syndrome leading in 50 of Hantaan cases to haemoconcentration. Dengue and hantaviruses are RNA viruses belonging to the Flaviviridae and Bunyaviridae families respectively. Other than being RNA viruses they do not share any other molecular common features.
Table1summarizes different aspects of dengue and hantavirus infections. Many new viruses have emerged with new paradigms of kidney injury either directly through their cytopathic effect or indirectly through immune-mediated glomerulopathy tubulointerstitial disease and acute kidney injury as part of multiorgan failure. Herein we will discuss Parvovirus which causes glomerulopathy and Hanta Ebola and Dengue viruses which cause viral hemorrhagic fever and.
Recent studies indicate that receptors directing dengue virus and hantavirus infection of the endothelium contribute to the dysregulation of normal endothelial cell signaling responses that control capillary permeability and immune responses that contribute to pathogenesis. The geographic origin of hantavirus infection was reported for 955 of all cases dengue virus 984. Hantavirus infections were acquired in Germany in 976 of cases n 2800.
In 2007 there was a marked increase of hantavirus cases mainly in areas known to be endemic for hantavirus. In 2006 imported cases of chikungunya fever primarily returned from several islands of. Some highly pathogenic viruses such as Chikungunya virus Japanese encephalitis virus Yellow fever virus Dengue virus Hanta virus SARS-CoV and H5N1 avian influenza virus can cause severe infectious diseases.
However the consensus method for detecting these viruses has not been well established. A rapid and sensitive microarray approach for detection of these viruses and a panel of. This article briefly reviews our knowledge of the importance of the disruption of the vascular endothelial barrier in two severe disease syndromes dengue hemorrhagic fever and hantavirus pulmonary syndrome.
Both viruses cause changes in vascular permeability without damaging the endothelium. Here we focus on our understanding of the virus interaction with the endothelium the role of the endothelium in the induced pathogenesis and the possible mechanisms by which each virus. Early symptoms include fatigue fever and muscle aches especially in the large muscle groupsthighs hips back and sometimes shoulders.
These symptoms are universal. There may also be headaches dizziness chills and abdominal problems such as nausea vomiting diarrhea and abdominal pain. There is no specific treatment cure or vaccine for hantavirus infection.
However we do know that if infected individuals are recognized early and receive medical care in an intensive care unit they may do better. In intensive care patients are intubated and given oxygen therapy to help them through the period of severe respiratory distress. Hantaviruses belong to the bunyavirus family of viruses.
There are 5 genera within the family. Bunyavirus phlebovirus nairovirus tospovirus and hantavirus. Each is made up of negative-sensed single-stranded RNA viruses.
All these genera include arthropod-borne viruses with the exception of hantavirus which is rodent-borne. Es gibt vier unterschiedliche Dengue-Virus-Typen 1 2 4 5 und nach einer durchgemachten Dengue besteht nur wenige Wochen bis Monate eine Kreuzimmunität. Danach kann man sich wieder ein.
Marburg virus has been linked to the recent death of a man in Uganda the Washington Post reported. Like Ebola Marburg belongs to the Filovirus family of viruses and is spread among humans when a.
