How is flavivirus diagnosed?

How is flavivirus diagnosed?

Flavivirus-associated human diseases can be reliably confirmed by the detection of viral nucleic acids using conventional reverse transcription (RT)-PCR or real-time RT-qPCR. The molecular diagnosis of flavivirus infection is dependent on the presence of viral nucleic acids in the sampled biological material.

Is flavivirus positive or negative?

Viruses in the flavivirus family are all single-stranded RNA viruses with linear non-segmented genomes. Viruses in this family are considered positive (+) sense because proteins are made directly from the template strand of RNA which is present in the viral capsid.

Is flavivirus a DNA or RNA virus?

The Flaviviridae are a family of positive, single-stranded, enveloped RNA viruses. They are found in arthropods, (primarily ticks and mosquitoes), and can occasionally infect humans.

Why is flavivirus significant?

Background. Flaviviruses are enveloped single-stranded RNA viruses and major human pathogens. They are responsible for causing outbreaks and therefore they represent a serious health issue worldwide (1).

What are the symptoms of flavivirus?

What are the symptoms of Flaviviridae? General symptoms include fever, body aches, headache, and joint pain. Some of these illness may also cause vomiting and diarrhea. The diseases caused by Flaviviridae viruses can be fatal.

Is HCV a flavivirus?

Intact Virion Hepatitis C virus (HCV) is an enveloped, positive-strand RNA virus classified in the Hepacivirus genus within the Flaviviridae family.

Is HCV a Flavivirus?

What are the symptoms of Flavivirus?

Why is it called the Flavivirus?

Flaviviruses are named for the yellow fever virus; the word flavus means ‘yellow’ in Latin, and yellow fever in turn is named from its propensity to cause yellow jaundice in victims.

What is a Flavivirus disease?

Flaviviruses are vector-borne RNA viruses that can emerge unexpectedly in human populations and cause a spectrum of potentially severe diseases including hepatitis, vascular shock syndrome, encephalitis, acute flaccid paralysis, congenital abnormalities and fetal death.

Which disease is caused by Flavivirus?

Species of Flaviviridae are transmitted by either insects or arachnids and cause severe diseases such as yellow fever, dengue, tick-borne encephalitis, and Japanese B encephalitis.

How do you treat Flavivirus?

At present, no vaccine or effective antiviral treatment exists for the prevention or treatment of infections with DENV. Supportive care and symptomatic treatment through hydration or aggressive fluid management, if hypotention develops during the course of DHV, are the most important aids to improve survival.
