What is dengue denv1?
Introduction. Dengue virus (DENV) is a single-stranded, positive-sense RNA virus belonging to the genus Flavivirus, family Flaviviridae [1].
What is the causes of dengue?
Dengue fever is caused by any one of four types of dengue viruses. You can’t get dengue fever from being around an infected person. Instead, dengue fever is spread through mosquito bites. The two types of mosquitoes that most often spread the dengue viruses are common both in and around human lodgings.
What are the 4 types of dengue fever?
Dengue is caused by a virus of the Flaviviridae family and there are four distinct, but closely related, serotypes of the virus that cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4).
What type of virus is dengue virus?
Dengue virus (DENV) belongs to the family Flaviviridae, genus Flavivirus. It is a single-stranded positive-sense ribonucleic acid virus with 10,700 bases. The genus Flavivirus includes other arthropod borne viruses such as yellow fever virus, West Nile virus, Zika virus, tick-borne encephalitis virus.
What is denv3?
Over the past two decades, dengue virus serotype 3 (DENV-3) has caused unexpected epidemics of dengue hemorrhagic fever (DHF) in Sri Lanka, East Africa, and Latin America. We used a phylogenetic approach to evaluate the roles of virus evolution and transport in the emergence of these outbreaks.
How much platelet count is normal in dengue?
Dengue fever can result in a drop in your white blood cell and platelet counts. The normal platelet count in the body ranges from 1.5 to 4 lacs, this can go down to as low as 20,000 to 40,000 in the case of dengue patients.
How can dengue be cured?
Dengue is a virus, so there is no specific treatment or cure. However, intervention can help, depending on how severe the disease is. For milder forms, treatment includes: Preventing dehydration: A high fever and vomiting can dehydrate the body.
Is dengue person to person?
Dengue cannot be spread directly from person to person. However, a person infected and suffering from dengue fever can infect other mosquitoes. Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.
How can dengue be transmitted?
Through Mosquito Bites Aedes aegypti mosquito. Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus).
Is dengue RNA or DNA?
Dengue virus (DENV) is the cause of dengue fever. It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus.
What does a positive denv-1-4 test result indicate?
Positive results on the CDC DENV-1-4 rRT-PCR multiplex assay indicate current dengue infection. Blood samples from patients suspected of having dengue taken 1-7 days after onset of fever should be tested with this test.
How many E and M proteins are in a DENV virus?
The glycoprotein shell of the mature DENV virion consists of 180 copies each of the E and M proteins. The immature virion starts out with the E and prM proteins forming 90 heterodimers that give a spiky exterior to the viral particle.
What is dengue virus?
Dengue is the fastest spreading vector-borne disease in the world endemic in 100 countries· Dengue virus has four serotypes (DENV1, DENV2, DENV3 and DENV4) First infection with one of the four serotypes usually is non-severe or asymptomatic, while second infection with one of other serotypes may cause severe dengue.
Can the CDC denv-1-4 rRT-PCR multiplex assay be used to screen for dengue?
The CDC DENV-1-4 rRT-PCR multiplex assay is not approved for the screening of blood or plasma donors. Positive results on the CDC DENV-1-4 rRT-PCR multiplex assay indicate current dengue infection. Blood samples from patients suspected of having dengue taken 1-7 days after onset of fever should be tested with this test.
