Gou virus

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. [1]

Contents

Natural reservoir

Gou virus was first isolated from black rats (R. rattus) captured in Zhejiang Province in 2000. [2] Genetically variant strains of GOUV have been found in black rats in Longquan, China. In addition, hantavirus strains isolated from R. flavipectus and R. norvegicus in Longquan are most closely related to GOUV. [3]

Transmission

Like all hantaviruses, transmission to humans is primarily through aerosolized rodent excreta and hand-to-mouth contamination from fomites. No human-to-human transmission has been documented. Longquan City, Zhejiang province, China, has a persistently high rate of human infection with GOUV. There is speculation that a variant strain of GOUV is transmissible from human-to-human. However, this has not yet been confirmed with epidemiological trace-back analysis. [4] [5] [6]

Morbidity and mortality

Between 1974-2011, in annual numbers (cases/100,000 population), a total of 20 patients died of HFRS in Longquan, with an average fatality rate of 1.07%. The highest fatalities were between 1974-1983 with an 11% death rate (10 deaths/91 cases). Seasonally, all deaths occurred in autumn and winter. No deaths have been reported since 2007. This is believed to be due to early diagnosis and improved supportive treatment. [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.

<i>Bunyavirales</i> Order of RNA viruses

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.

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.

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.

<span class="mw-page-title-main">Hantavirus hemorrhagic fever with renal syndrome</span> Group of clinically similar illnesses caused by species of hantaviruses

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.
