Hepatitis D is a type of viral hepatitis caused by the hepatitis delta virus (HDV). HDV is one of five known hepatitis viruses: A, B, C, D, and E. HDV is considered to be a satellite because it can propagate only in the presence of the hepatitis B virus (HBV). Transmission of HDV can occur either via simultaneous infection with HBV (coinfection) or superimposed on chronic hepatitis B or hepatitis B carrier state (superinfection).
Oropouche fever is a tropical viral infection which can infect humans. It is transmitted by biting midges and mosquitoes, from a natural reservoir which includes sloths, non-human primates, and birds. The disease is named after the region where it was first discovered and isolated in 1955, by the Oropouche River in Trinidad and Tobago. Oropouche fever is caused by the Oropouche virus (OROV), of the Bunyavirales order of viruses.
Thogotovirus is a genus of enveloped RNA viruses, one of seven genera in the virus family Orthomyxoviridae. Their single-stranded, negative-sense RNA genome has six or seven segments. Thogotoviruses are distinguished from most other orthomyxoviruses by being arboviruses – viruses that are transmitted by arthropods, in this case usually ticks. Thogotoviruses can replicate in both tick cells and vertebrate cells; one subtype has also been isolated from mosquitoes. A consequence of being transmitted by blood-sucking vectors is that the virus must spread systemically in the vertebrate host – unlike influenza viruses, which are transmitted by respiratory droplets and are usually confined to the respiratory system.
Oropouche orthobunyavirus (OROV) is one of the most common orthobunyaviruses. When OROV infects humans, it causes a rapid fever illness called Oropouche fever. OROV was originally reported in Trinidad and Tobago in 1955 from the blood sample of a fever patient and from a pool of Coquillettidia venezuelensis mosquitoes. In 1960, OROV was isolated from a sloth and a pool of Ochlerotatus serratus mosquitoes in Brazil. The virus is considered a public health threat in tropical and subtropical areas of Central and South America, with over half a million infected people as of 2005. OROV is considered to be an arbovirus due to the method of transmission by the mosquitoes Aedes serratus and Culex quinquefasciatus among sloths, marsupials, primates, and birds.
Phlebovirus is one of twenty genera of the family Phenuiviridae in the order Bunyavirales. The genus contains 66 species. It derives its name from Phlebotominae, the vectors of member species 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).
Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). VEE can affect all equine species, such as horses, donkeys, and zebras. After infection, equines may suddenly die or show progressive central nervous system disorders. Humans also can contract this disease. Healthy adults who become infected by the virus may experience flu-like symptoms, such as high fevers and headaches. People with weakened immune systems and the young and the elderly can become severely ill or die from this disease.
Dhori virus (DHOV) is a species of the genus Thogotovirus and a member of the family Orthomyxoviridae. It is infectious to humans, but its host is most commonly Ixodidae ticks, and can also infect other species of ticks, mosquitoes, and mammals. DHOV is lethal to mice, leads to high rates of miscarriages in sheep and goats, and causes systemic pathologic changes similar to those reported in humans with virulent influenza A (H5N1) virus infection.
Haemagogus is a genus of mosquitoes in the dipteran family Culicidae. They mainly occur in Central America and northern South America, although some species inhabit forested areas of Brazil, and range as far as northern Argentina. In the Rio Grande Do Sul area of Brazil, one species, H. leucocelaenus, has been found carrying yellow fever virus. Several species have a distinct metallic sheen.
Alenquer is a municipality in the state of Pará in the Northern region of Brazil. The town is located on the northern bank of the Amazon River, roughly across from the city of Santarém.
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.
Nyavirus is a genus of negative-strand RNA viruses in the family Nyamiviridae. Ticks and birds serve as natural hosts. There are four species in this genus.
Bovine coronavirus is a coronavirus which is a member of the species Betacoronavirus 1. The infecting virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid receptor. Infection causes calf enteritis and contributes to the enzootic pneumonia complex in calves. It can also cause winter dysentery in adult cattle. It can infect both domestic and wild ruminants and has a worldwide distribution. Transmission is horizontal, via oro-fecal or respiratory routes. Like other coronaviruses from genus Betacoronavirus, subgenus Embecovirus, it has a surface protein called hemagglutinin esterase (HE) in addition to the four structural proteins shared by all coronaviruses.
St. Abbs Head virus (SAHV) is a virus in the genus Phlebovirus, order Bunyavirales. It is named after St Abb's Head, Scotland, where it was isolated from its vector, the tick Ixodes uriae.
Naples phlebovirus is an antigenic species of genus Phlebovirus within the family Phenuiviridae of the order Bunyavirales. It is an enveloped RNA virus with a tripartite genome e Uukuniemi (UUK) serogroup. The Sandfly group's natural reservoir are sandflies, while the natural reservoir for Uukuniemi is ticks. The SFNV serogroup consists of two main serocomplexes associated with disease in humans, the Naples and Sicilian serocomplexes. Sandfly fever induces myalgia, fever, and elevated liver enzymes in humans. It is difficult to diagnose outside endemic areas.
Candiru phlebovirus (CDUV) is a species of virus in the genus Phlebovirus.
The 75V-2621 virus is a strain of Gamboa virus in the genus Bunyavirus. It was first isolated in the mosquito Aedeomyia squamipennis in Vinces, Ecuador in 1974. Ad. squamipennis appears to be the vector and birds a host, including the chicken Gallus gallus domesticus under experimental conditions. It has only been isolated in the tropical regions of Central and South America. It has not be shown to cause disease in humans, or domestic and wild animals; however, in a 2018 study, antibodies against the Gamboa virus were found in birds (6.2%), humans (1.5%), and other wild animals (2.6%).
Bourbon virus is an RNA virus in the genus Thogotovirus of the family Orthomyxoviridae, which is similar to Dhori virus and Batken virus. It was first identified in 2014 in a man from Bourbon County, Kansas, United States, who died after being bitten by ticks. The case is the eighth report of human disease associated with a thogotovirus globally, and the first in the Western hemisphere. As of May 2015, a case was discovered in Stillwater, Oklahoma, and relatively little is known about the virus. No specific treatment or vaccine is available. The virus is suspected to be transmitted by ticks or insects, and avoidance of bites is recommended to reduce risk of infection. In June 2017 a 58-year-old female Missouri State Park employee died from an infection of the Bourbon virus after it had been misdiagnosed for a significant period of time.
Quaranfil quaranjavirus is the type virus of the Quaranjavirus genus in the virus family Orthomyxoviridae. It has a negative sense, single-stranded RNA genome composed of 6 segments. Its hosts are ticks, birds, and humans. It was isolated from ticks near Cairo, Egypt in 1953. The virus can infect humans, as confirmed by serological study of human serum samples in Egypt in the 1960s that showed that 8% of the local population had neutralizing antibodies to the virus. The virus has not yet been connected to a human disease.
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. Until 2011, member genus Phlebovirus was the only genus of the family with viruses causing disease in humans except Dabie bandavirus.
