Is hepatitis A genus?
Hepatovirus
Hepatitis A virus/Genus
What disease does Hepatovirus cause?
Hepatitis A is an infectious disease of the liver caused by Hepatovirus A (HAV); it is a type of viral hepatitis. Many cases have few or no symptoms, especially in the young. The time between infection and symptoms, in those who develop them, is 2–6 weeks.
Where is Hepatovirus found?
Hepatitis A (HAV) (genus Hepatovirus), a picornavirus transmitted via fecal-oral routes is found worldwide. Humans are the probable natural host, but hepatitis A can be spread from human to primate, primate to primate, and primate to human, and there are nonhuman primate host-specific strains of HAV (Robertson, 2001).
What is the scientific name for hepatitis?
Hepatitis A virus (HAV), classified as hepatovirus, is a small, unenveloped symmetrical RNA virus which shares many of the characteristics of the picornavirus family, and is the cause of infectious or epidemic hepatitis transmitted by the fecal-oral route.
What is the genus species name for hepatitis A?
Hepatitis A virus/Genus
Hepatitis A HAV is a single-stranded RNA virus that is a member of the genus Hepatovirus of the family Picornaviridae (“small RNA virus”).
Is Hepatitis Ca a DNA virus?
The hepatitis C virus (HCV) is a RNA virus. In a DNA virus there are two complementary and intertwined strands of nucleic acid (the double helix). The structure of DNA resembles two interlocking spirals, and when reproduction takes places the genetic code of the parent is correctly imposed on the child.
What is the death rate of hepatitis A?
Overall case-fatality estimates range from 0.3% to 0.6% for all ages and up to 1.8% among adults age 50 years or older. During outbreaks concentrated in older individuals or higher proportions of individuals with comorbidities, case-fatality rates can be significantly higher.
Is Hep A killed by cooking?
The hepatitis A virus can survive outside the body for months. Heating food and liquids to temperatures of 185°F (85°C) for at least 1 minute can kill the virus. Exposure to freezing temperatures does not kill the virus.
What is the genus and species of Hepatitis A?
How big is the genome of a Hepatovirus?
HAV is classified as a Hepatovirus of the Picornaviridae family. HAV is a 27- to 32-nm, nonenveloped, icosahedral positive single-stranded linear RNA virus with an approximately 7.5-kb genome.
What is the G + C content of Hepatovirus?
The G+C content of HAV genomes is unusually low at about 38%. Hepatitis A virus (HAV) is classified into Hepatovirus genus within the Picornaviridae family. Mature virions are approximately 27–32 nm in diameter and can only be visualized under an electron microscope ( Figure 1 ).
How long is the incubation period for Hepatovirus?
The hepatitis A virus (HAV), a nonenveloped picornavirus, genus Hepatovirus, is transmitted predominantly by the fecal-oral route, with an average incubation period of 28 days (range, 15 to 50 days) with signs or symptoms persisting for less than 2 months.
What are the 12 genera of picornavirus virus?
Picornaviruses (family Picornaviridae) are small, non-enveloped viruses with single-stranded, positive-sense genomic RNA; they are divided into 12 genera: Aphthovirus, Avihepatovirus, Cardiovirus, Enterovirus, Erbovirus, Hepatovirus, Parechovirus, Sapelovirus, Senecavirus, Teschovirus, Tremovirus, and Kobuvirus (1).
