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 ( Hylomyscus simus ) 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. [2]
The virus genome consists of three segments of negative-stranded RNA; the large (L) segment encodes the viral RNA-dependent RNA polymerase, the medium (M) segment encodes the envelope glycoproteins Gn and Gc (cotranslationally cleaved from a glycoprotein precursor), and the small (S) segment encodes the nucleocapsid (N) protein. [2]
In rodents, hantavirus produces a chronic infection with no adverse sequelae. In humans, hantavirus produces two major clinical syndromes: hemorrhagic fever or pulmonary syndrome. European, Asian, and African rodent-borne hantaviruses cause hemorrhagic fever. The pulmonary syndrome, caused by the species Sin Nombre orthohantavirus , has not been found anywhere other than the United States[ dubious ] where deer mice are the natural hosts. It was discovered in 1993 during an outbreak in the Four Corners region of the southwestern United States. [3] [4]
Natural reservoirs for this hantavirus species include the slit faced bat, moles, and shrews. Rodent-borne hantaviruses form three major evolutionary clades corresponding to the subfamilies of their rodent hosts. HTNV, SEOV, and DOBV are examples of Murinae-associated hantaviruses. PUUV and Tula orthohantavirus (TULV) belong to the Arvicolinae-associated hantaviruses, and SNV and ANDV are representatives of Neotominae- and Sigmodontinae-associated hantaviruses. [2] [5]
Orthohantavirus is a genus of single-stranded, enveloped, negative-sense RNA viruses in the family Hantaviridae within the order Bunyavirales. Members of this genus may be called orthohantaviruses or simply hantaviruses.
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.
Seoul orthohantavirus (SEOV) is a member of the Orthohantavirus family of rodent-borne viruses and is one of the 4 hantaviruses that are known to be able to cause Hantavirus hemorrhagic fever with renal syndrome (HFRS). It is an Old World hantavirus; a negative sense, single-stranded, tri-segmented RNA virus.
Andes orthohantavirus (ANDV), a species of Orthohantavirus, is a major causative agent of hantavirus cardiopulmonary syndrome (HCPS) and hantavirus pulmonary syndrome (HPS) in South America. It is named for the Andes mountains of Chile and Argentina, where it was first discovered. Originating in the reservoir of rodents, Andes orthohantavirus is easily transmitted to humans who come into contact with infected rodents or their fecal droppings. However, infected rodents do not appear ill, so there is no readily apparent indicator to determine whether the rodent is infected or not. Additionally, Andes orthohantavirus, specifically, is the only hantavirus that can be spread by human to human contact via bodily fluids or long-term contact from one infected individual to a healthy person.
Black Creek Canal orthohantavirus (BCCV) is a single-stranded, negative sense RNA virus species of New World Orthohantavirus. It was first isolated in cotton rats found in the Black Creek Canal area of Dade County, Florida in 1995. The discovery followed from an isolated case of Hantavirus pulmonary syndrome diagnosed in a Dade County resident.
Hantavirus hemorrhagic fever with renal syndrome (HFRS) is a group of clinically similar illnesses caused by species of hantaviruses. It is also known as Korean hemorrhagic fever and epidemic hemorrhagic fever. It is found in Europe, Asia, and Africa. The species that cause HFRS include Hantaan orthohantavirus, Dobrava-Belgrade orthohantavirus, Saaremaa virus, Seoul orthohantavirus, Puumala orthohantavirus and other orthohantaviruses. Of these species, Hantaan River virus and Dobrava-Belgrade virus cause the most severe form of the syndrome and have the highest morbidity rates. When caused by the Puumala virus, it is also called nephropathia epidemica. This infection is known as sorkfeber in Swedish, myyräkuume in Finnish, and musepest in Norwegian.
Dobrava-Belgrade orthohantavirus (DOBV), also known as Dobrava virus, is an enveloped, single-stranded, negative-sense RNA virus species of Old World Orthohantavirus. It is one of several species of Hantavirus that is the causative agent of severe Hantavirus hemorrhagic fever with renal syndrome. It was first isolated in 1985 from a yellow-necked mouse found in the village of Dobrava, southeastern Slovenia. It was subsequently isolated in striped field mice in Russia and other parts of Eastern Europe. It has also been found in Germany but the reservoir host there is unknown.
Soochong virus (SOOV) is a zoonotic negative sense single-stranded RNA virus. It may be a member of the genus Orthohantavirus, but it has not be definitively classified as a species and may only be a strain. It is one of four rodent-borne Hantaviruses found in the Republic of Korea. It is the etiologic agent for Hantavirus hemorrhagic fever with renal syndrome (HFRS). The other species responsible for HFRS in Korea are Seoul virus, Haantan virus, and Muju virus.
Muju virus(MUV) is a zoonotic negative-sense single-stranded RNA virus of the genus Orthohantavirus. It is a member virus of Puumala orthohantavirus. It is one of four rodent-borne Hantaviruses found in the Republic of Korea. It is the etiologic agent for Hantavirus hemorrhagic fever with renal syndrome (HFRS). The other species responsible for HFRS in Korea are Seoul orthohantavirus, Hantaan orthohantavirus, and Soochong virus.
Monongahela virus (MGLV) is a single-stranded, negative-sense Orthohantavirus virus of zoonotic origin that causes hantavirus pulmonary syndrome.
Tula orthohantavirus, formerly Tula virus, (TULV) is a single-stranded, negative-sense RNA virus species of orthohantavirus first isolated from a European common vole found in Central Russia. It causes Hantavirus hemorrhagic fever with renal syndrome. The Microtus species are also found in North America, Europe, Scandinavia, Slovenia, Asia, and Western Russia. Human cases of Tula orthohantavirus have also been reported in Switzerland and Germany.
Hantaan orthohantavirus (HTNV) is an enveloped, single-stranded, negative-sense RNA virus species of Old World Orthohantavirus. It is the causative agent of Korean hemorrhagic fever in humans. It is named for the Hantan River in South Korea, and in turn lends the name to its genus Orthohantavirus and family Hantaviridae.
Tanganya virus(TGNV) is an enveloped, single-stranded, negative-sense RNA virus, possibly of the genus orthohantavirus in the Bunyavirales order. It is the second indigenous Murinae-associated African hantavirus to be discovered. It has a low sequence similarity to other hantaviruses and serologically distinct from other hantaviruses. Its host is Crocidura theresae.
Nova virus is a single-stranded, negative-sense, enveloped RNA virus with a trisegmented genome. It is one of the most divergent lineages of the hantavirus group – zoonotic viruses of the family Bunyaviridae. No known human cases of infection have yet been reported
Rockport virus (RKPV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus.
Asama orthohantavirus(ASAV), also called Asama virus, is a single-stranded, enveloped, segmented negative-sense RNA hantavirus. The hantavirus was isolated in Japan from Japanese shrew mole. Hantaviruses harbored by shrews are genetically closer to ASAV than to hantaviruses harbored by rodents. Host-switching may be evident in the future due to the viruses closeness to soricine shrew-borne hantaviruses. The detection of the ASAV was the first hantavirus found to be hosted by members of the family Talpidae, which includes shrew moles. Thoughts on hantavirus evolutionary history has expanded due to the discovery of ASAV.

Tanganya orthohantavirus (TGNV) is a viral isolate detected in tissue samples from Crocidura douceti. The putative host shrews were captured near the village of Tanganya, Guinea, in January 2004.
