The genus Ebolavirus is a virological taxon included in the family Filoviridae, order Mononegavirales. The members of this genus are called ebolaviruses, and encode their genome in the form of single-stranded negative-sense RNA. The six known virus species are named for the region where each was originally identified: Bundibugyo ebolavirus, Reston ebolavirus, Sudan ebolavirus, Taï Forest ebolavirus, Zaire ebolavirus, and Bombali ebolavirus. The last is the most recent species to be named and was isolated from Angolan free-tailed bats in Sierra Leone.
Bunyavirales is an order of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. It is the only order in the class Ellioviricetes. The name Bunyavirales derives from Bunyamwera, where the original type species Bunyamwera orthobunyavirus was first discovered. Ellioviricetes is named in honor of late virologist Richard M. Elliott for his early work on bunyaviruses.
Bwamba orthobunyavirus (BWAV) belongs to the genus Orthobunyavirus and the order Bunyavirales RNA viruses. BWAV is present in large parts of Africa, endemic in Mozambique, Tanzania and Uganda. It is transmitted to humans through mosquito bites and results in a brief benign generalised infection with headache, skin rash, diarrhea and joint pain and lasts 4–5 days. The animal reservoir of the virus includes birds, monkeys and donkeys.
Phlebotomus is a genus of "sand flies" in the Diptera family Psychodidae. In the past, they have sometimes been considered to belong in a separate family, Phlebotomidae, but this alternative classification has not gained wide acceptance.
Phlebovirus is one of four genera of the family Phenuiviridae in the order Bunyavirales. The genus currently comprises 60 species. It derives its name from Phlebotominae, the vectors of member species Sandfly fever Naples phlebovirus, which is said to be ultimately from the Greek phlebos, meaning "vein". The proper word for "vein" in ancient Greek is however phleps (φλέψ).
Orthonairovirus is a genus in the family Nairoviridae of the order Bunyavirales that include viruses with circular, negative-sense single stranded RNA. It got its name from the Nairobi sheep disease that affects the gastrointestinal tracts of sheep and goats. The vast majority, and perhaps all viruses in this genus are tick-borne viruses that can have human or other vertebrate hosts.
Toscana phlebovirus (TOSV) is an arbovirus belonging to Bunyavirales, an order of negative-stranded, enveloped RNA viruses. The virus can be transmitted to humans by the bite of an infected sandfly of the genus Phlebotomus. Toscana is not normally associated with disease, as indicated by high seroprevalence rates in endemic areas, but in common with other sandfly transmitted viruses such as Naples virus and Sicilian virus, infection may result in Pappataci fever, an illness with mild fever, headache and myalgia. In serious cases that go undiagnosed, acute meningitis, meningoencephalitis and encephalitis may occur. There is no specific treatment for infection, so treatment is supportive, reducing the severity of symptoms until the immune system has cleared the infection.
Dabie bandavirus, also called SFTS virus, is a tick-borne virus in the genus Bandavirus in the family Phenuiviridae, order Bunyavirales. The clinical condition it caused is known as severe fever with thrombocytopenia syndrome (SFTS). SFTS is an emerging infectious disease that was first described in northeast and central China 2009 and now has also been discovered in Japan, South Korea, Vietnam and Taiwan in 2015. SFTS has a fatality rate of 12% and as high as over 30% in some areas. The major clinical symptoms of SFTS are fever, vomiting, diarrhea, multiple organ failure, thrombocytopenia, leukopenia and elevated liver enzyme levels. Another outbreak occurred in East China in the early half of 2020.
The species Bundibugyo ebolavirus is the taxonomic home of one virus, Bundibugyo virus (BDBV), that forms filamentous virions and is closely related to the infamous Ebola virus (EBOV). The virus causes severe disease in humans in the form of viral hemorrhagic fever and is a Select agent, World Health Organization Risk Group 4 Pathogen, National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogen, Centers for Disease Control and Prevention Category A Bioterrorism Agent, and is listed as a Biological Agent for Export Control by the Australia Group.
Heartland bandavirus, sometimes called Heartland virus (HRTV), is a tick-borne phlebovirus of the Bhanja virus serocomplex discovered in 2009. The lone star tick transmits the virus to people when feeding on blood. As of 2017, only five Midwestern United States have reported 20 human infections, namely Arkansas, Indiana, Missouri, Oklahoma, and Tennessee; symptoms resemble those of two other tick-borne infections ehrlichiosis and anaplasmosis. The reservoir host is unknown, but deer, raccoon, coyotes, and moose in 13 different states have antibody titers against the virus.
Sangassou orthohantavirus(SANGV) is single-stranded, negative-sense RNA virus species of the genus Orthohantavirus in the Bunyavirales order. It was first isolated in an African wood mouse in the forest in Guinea, West Africa in 2010. It is named for the village near where the mouse was trapped. It is the first indigenous Murinae-associated African hantavirus to be discovered.
Alenquer phlebovirus (ALEV) is a virus in the genus Phlebovirus. Alenquer phlebovirus was one of eight arthropod-borne viruses first isolated in the early 1980s from sites along roads built into the Amazon rainforest in Brazil for settlers. Sporadic cases of febrile illness have occurred in humans who live in jungle areas in Brazil and Panama.
Candiru phlebovirus (CDUV) is a species virus in the genus Phlebovirus.
Acara orthobunyavirus (ACAV) is a species in the genus Orthobunyavirus, belonging to the Capim serogroup. It is isolated from sentinel mice, Culex species, and the rodent Nectomys squamipes in Pará, Brazil and in Panama. The symptoms of the Acará virus is death. Sometimes reported to cause disease in humans.
In 1954 the Hazara orthonairovirus, one of the 34 tick-borne viruses of the genus Orthonairovirus, was discovered in Pakistan in the Ixodes tick native to that region. Today this virus is studied in mice in an attempt to develop treatments for the highly pathogenic Crimean-Congo Hemorrhagic Fever virus.
Batai orthobunyavirus (BATV) is a RNA virus belonging to order Bunyavirales, genus Orthobunyavirus.
Cache Valley orthobunyavirus (CVV) is a member of the order Bunyavirales, genus Orthobunyavirus, and serogroup Bunyamwera, which was first isolated in 1956 from Culiseta inornata mosquitos collected in Utah's Cache Valley. CVV is an enveloped arbovirus, nominally 80–120 nm in diameter, whose genome is composed of three single-stranded, negative-sense RNA segments. The large segment of related bunyaviruses is approximately 6800 bases in length and encodes a probable viral polymerase. The middle CVV segment has a 4463-nucleotide sequence and the smallest segment encodes for the nucleocapsid, and a second non-structural protein. CVV has been known to cause outbreaks of spontaneous abortion and congenital malformations in ruminants such as sheep and cattle. CVV rarely infects humans, but when they are infected it has caused encephalitis and multiorgan failure.
The Punta Toro virus is a member of the genus Phlebovirus of the order Bunyavirales. It was initially isolated from patients in Colombia and two key patients in Panama. Two individual serotypes of PTV were isolated from these patients, PTV-Adames (A) and PTV-Balliet (B), with PTV-A appearing to be more virulent. PTV is considered to be relatively contained to the Americas with no cases being reported outside of this region. Along with a few other human pathogenic Phleboviruses, PTV is considered to be a significant virus in terms of public health as little information is known about its clinical effects and with further research underway, PTV could have unforeseen impacts on health and virology.
Phenuiviridae is a family of negative-strand RNA viruses in the order Bunyavirales. Ruminants, camels, humans, and mosquitoes serve as natural hosts. Member genus Phlebovirus is the only genus of the family that has viruses that cause disease in humans.
The Nairobi sheep disease orthonairovirus (NSDV), also known as Ganjam virus is a species in the genus Orthonairovirus belonging to the Nairobi sheep disease serogroup. NSDV's known hosts belong to the hard tick family Ixodidae, including Rhipicephalus appendiculatus, and Amblyomma variegatum, and afflict sheep and goats naturally. The virus is in the family Nairoviridae and order Bunyavirales.
