What kind of virus is arenavirus?
What kind of virus is arenavirus?
An arenavirus is a bisegmented ambisense RNA virus that is a member of the family Arenaviridae. These viruses infect rodents and occasionally humans. A class of novel, highly divergent arenaviruses, properly known as reptarenaviruses, have also been discovered which infect snakes to produce inclusion body disease.
What causes arenavirus?
Arenaviruses cause diseases with two types of clinical presentations: neurological and hemorrhagic fever. However, asymptomatic arenavirus infection may occur. Neurological: aseptic meningitis, encephalitis or meningoencephalitis, caused by the LCM virus. Overall case fatality is <1%.
How do you treat arenavirus?
What is the treatment? There is no specific treatment for most of these illnesses. Some of the illnesses, such as Lassa fever, respond to anti-viral therapies if they are treated during the first week of illness. Supportive therapy, including managing secondary bacterial infections, may also help reduce mortality.
What was the first arenavirus found to cause hemorrhagic fever?
The Machupo virus is an Arenavirus endemic to Bolivia that causes the disease commonly called Bolivian hemorrhagic fever. It was first discovered in 1959 in an outbreak in San Joaquin, Bolivia.
What is Arenavirus snake?
A few years ago a novel group of arenaviruses were identified in and isolated from snakes with BIBD [4, 5, 7]. Arenaviruses are negative-sense RNA viruses with two genome segments, L and S, which encode Z protein and RNA-dependent RNA polymerase, and glycoprotein precursor and nucleoprotein (NP), respectively [8].
Is Ebola an arenavirus?
They found the culprit – a previously undescribed arenavirus – and uncovered something surprising: the Arenavirus’s glycoprotein, a viral “access badge” to the secure insides of a cell, actually belonged to the Ebola virus.
What causes IBD in snakes?
The cause of IBD is not yet confirmed; however, a viral infection (a type of retrovirus) has historically been considered the most likely cause. Recently, mounting evidence has pointed to a new and unusual arenavirus in the genus Reptarenavirus as the cause of IBD.
What is inclusion body disease?
Inclusion body disease (IBD) is an infectious and invariably fatal viral disease affecting captive specimens of the boid family of snakes, particularly Boa constrictor. It has been recognized since the mid-1970s.
What is the treatment of adenovirus?
There is no specific treatment for people with adenovirus infection. Most adenovirus infections are mild and may require only care to help relieve symptoms, such as over-the-counter pain medicines or fever reducers. Always read the label and use medications as directed.
