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. [1]
During this outbreak, a high seroprevalence was found among the general population, suggesting that this virus has an extremely low pathogenicity and causes sub-clinical to mild symptoms. This was confirmed in a study that infected hamsters with CHOV. All of the hamsters tested positive for CHOV, but none exhibited any symptoms. [2]
The virus was isolated from the northern pygmy rice rat in El Choclo in the Los Santos Province in western Panama.[ citation needed ]
Choclo orthohantavirus has not been shown to transfer from person-to-person. Transmission by aerosolized rodent excreta still remains the only known way the virus is transmitted to humans. In general, droplet and/or fomite transfer has not been shown in the hantaviruses in general, in either the hemorrhagic or pulmonary forms. [3] [4] [5]
There were a total of eleven cases reported but only nine serologically confirmed cases of Choclo orthohantavirus found in this outbreak. A serologic survey of residents in the area revealed a 13% antibody prevalence. No person-to-person transmissions were found. There were no fatalities among serologically confirmed cases. There were three fatalities among those who tested negative for the virus. Before this outbreak, there were no documented cases of human hantavirus infections in Central America. [5] [6] [7]
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.
Sin Nombre orthohantavirus (SNV) is the prototypical etiologic agent of hantavirus cardiopulmonary syndrome (HCPS).
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.
New York orthohantavirus or New York virus is an Orthohantavirus. It is considered a strain of Sin Nombre orthohantavirus. It was first isolated from a white-footed mouse caught on an island off New York. The virus is associated with typical hantavirus pulmonary syndrome.
Bayou orthohantavirus (BAYV) is a species of Orthohantavirus first identified in 1993 in Louisiana. and later confirmed by other investigators. In 1996, the marsh rice rat was identified as the natural reservoir of the virus, indicating the virus to be widespread throughout the Southeastern United States. BAYV infection causes hantavirus pulmonary syndrome (HPS) and represents the second most common hantavirus in the United States behind the Sin Nombre orthohantavirus.
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.
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.
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.
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.

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.
Calabazo virus is an enveloped, single-stranded, negative-sense RNA hantavirus species of the order Bunyavirales. It is a novel New World microtine rodent-borne hantavirus discovered in Central America on the Azuero Peninsula of Panama in early 2000. Human infection with Calabazo virus results in respiratory illness similar to Hantavirus pulmonary syndrome but it is not severe or fatal and rarely requires hospitalization.
