Thailand virus (THAIV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus. [1]
THAIV was first isolated from rodents in two Thai provinces, Nakhon Pathom Province and Nakhon Ratchasima Province, in 1994. [2] The greater bandicoot rat (Bandicota indica) was found to be the primary reservoir for THAIV. Serological studies have revealed, but not confirmed, other rodents in Thailand as possible reservoirs, including the black rat (Rattus rattus), Polynesian rat (R. exulans), brown rat (R. norvegicus) and lesser rice-field rat (R. losea). [1] [3] [4] [5] [6]
Thailand virus (THAIV) is genetically diverse from other hantaviruses. The L, M, and S nucleotide segments reveal its most recent ancestor in common to be the Seoul virus(SEOV). However, four recently isolated THAIV strains from R.Rattus show genetic diversity between themselves and are distinct from SEOV in that they show geographical clustering. This is a distinct feature of all hantaviruses, except for SEOV. The SEOV strains have been primarily isolated from R. norvegicus. [7] [8]
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.
Amur virus (AMRV) 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 has been identified as a causative agent of hemorrhagic fever with renal syndrome.
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.
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.
Hantavirus pulmonary syndrome (HPS) is one of two potentially fatal syndromes of zoonotic origin caused by species of hantavirus. These include Black Creek Canal virus (BCCV), New York orthohantavirus (NYV), Monongahela virus (MGLV), Sin Nombre orthohantavirus (SNV), and certain other members of hantavirus genera that are native to the United States and Canada.
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.
Prospect Hill orthohantavirus is a single-stranded, negative-sense Hantaan-like zoonotic RNA virus isolated from meadow voles and microtine and other cricetid rodents in the United States. It has a widespread distribution in Pennsylvania, Maryland, West Virginia, Minnesota and California. The overall risk of infection in humans is low. It was first isolated from a meadow vole found in Prospect Hill, Maryland for which it is named.
Monongahela virus (MGLV) is a single-stranded, negative-sense Orthohantavirus virus of zoonotic origin that causes hantavirus pulmonary syndrome.
Limestone Canyon virus (LSC) is a single-stranded, negative-sense RNA zoonotic Orthohantavirus that is genetically similar to Sin Nombre orthohantavirus which causes Hantavirus pulmonary syndrome (HPS) in humans. HPS causing hantaviruses are found only in the United States and South America.
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.
Imjin thottimvirus(MJNV) is a single-stranded, enveloped, negative-sense RNA virus of the orthohantavirus genus in the Bunyavirales order. It is a newly identified hantavirus isolated from the lung tissues of Ussuri white-toothed shrews of the species Crocidura lasiura captured near the demilitarized zone in the Republic of Korea during 2004 and 2005.
Khabarovsk virus(KBR) is a orthohantavirus in the Bunyavirales order isolated from Microtus fortis discovered in far-east Russia. It is an enveloped, negative-sense RNA virus.
Choclo orthohantavirus (CHOV) is a single-stranded, negative-sense RNA zoonotic New World hantavirus. It was first isolated in 1999 in western Panama. The finding marked the first time Hantavirus pulmonary syndrome (HPS) was found in Central America.
Rockport virus (RKPV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus.
Serang virus(SERV) is a single-stranded, negative-sense, enveloped, novel RNA orthohantavirus.
Gou virus (GOUV) is a single-stranded, negative-sense, enveloped novel RNA orthohantavirus. It is one of the known hantaviruses responsible for hantavirus hemorrhagic fever with renal syndrome in humans.
Hantavirus vaccine is a vaccine that protects in humans against hantavirus infections causing hantavirus hemorrhagic fever with renal syndrome (HFRS) or hantavirus pulmonary syndrome (HPS). The vaccine is considered important as acute hantavirus infections are responsible for significant morbidity and mortality worldwide. It is estimated that about 1.5 million cases and 46,000 deaths occurred in China from 1950 to 2007. The number of cases is estimated at 32,000 in Finland from 2005 to 2010 and 90,000 in Russia from 1996 to 2006.
