Thailand Virus
Thailand virus (THAIV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus. Natural reservoir THAIV was first isolated from rodents in two Thai provinces, Nakhon Pathom Province and Nakhon Ratchasima Province, in 1994. 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''). Virology 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 featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthohantavirus
''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. Orthohantaviruses typically cause chronic asymptomatic infection in rodents. Humans may become infected with hantaviruses through contact with rodent urine, saliva, or feces. Some strains cause potentially fatal diseases in humans, such as hantavirus hemorrhagic fever with renal syndrome (HFRS), or hantavirus pulmonary syndrome (HPS), also known as hantavirus cardiopulmonary syndrome (HCPS), while others have not been associated with known human disease (e.g. Prospect Hill virus). HPS (HCPS) is a "rare respiratory illness associated with the inhalation of aerosolized rodent excreta (urine and feces) contaminated by hantavirus particles." Human infections of hantaviruses have almost entirely been linked to human contact with rodent excrement; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greater Bandicoot Rat
The greater bandicoot rat or Indian bandicoot rat (''Bandicota indica'') is a species of rodent in the family Muridae found in Bangladesh, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Taiwan, Thailand, and Vietnam akistan It can grow to about 27–29 cm without including the tail which can grow to 28 cm. These should not be confused with marsupial bandicoots which inhabit Australia and neighbouring New Guinea, which were named after the bandicota rats. Description The greater bandicoot rat has a dark gray-brown upper parts with a profusion of long, black hairs. Sides are gray with a few long, black hairs. Short, light gray fur occurs on the ventral surfaces. It has a dark and naked, scaly tail, and dark feet with light-colored claws. The young are much lighter in colour. In Sri Lanka, the bandicoot rat is known as - in the Sinhala language, the meaning of which directly translates to "pig-rat". These are one of several animals called in t ...

Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

Polynesian Rat
The Polynesian rat, Pacific rat or little rat (''Rattus exulans''), known to the Māori as ''kiore'', is the third most widespread species of rat in the world behind the brown rat and black rat. The Polynesian rat originated in Southeast Asia, and like its relatives has become widespread, migrating to most of Polynesia, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution. Description The Polynesian rat is similar in appearance to other rats, such as the black rat and the brown rat. It has large, round ears, a pointed snout, black/brown hair with a lighter belly, and comparatively small feet. It has a thin, long body, reaching up to in length from the nose to the base of the tail, making it slightly smaller than other human-associated r ...

Brown Rat
The brown rat (''Rattus norvegicus''), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat, Norwegian rat and Parisian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a head and body length of up to long, and a tail slightly shorter than that. It weighs between . Thought to have originated in northern China and neighbouring areas, this rodent has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas. Selective breeding of the brown rat has produced the fancy rat (rats kept as pets), as well as the laboratory rat (rats used as model organisms in biological research). Both fancy rats and laboratory rats are of the domesticated subspecies ''Rattus norvegicus domestica''. Studies of wild rats in New York City have shown that populations livi ...

Seoul Virus
''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).US Centers for Disease Control''Virology, Hantaviruses''Page last reviewed: August 29, 2012. It is an Old World hantavirus; a negative sense, single-stranded, tri-segmented RNA virus. Seoul virus is found in ''Rattus'' species rats, most commonly ''Rattus norvegicus,'' but occasionally ''Rattus rattus''. The two distinct hantaviruses have been identified in Korea in 1976, from '' Apodemus agrarius'', and in 1980, from ''Rattus norvegicus''. In 1994, a genetically different hantavirus was identified from '' Apodemus peninsulae''. Rats do not show physiological symptoms when carrying the virus, but humans can be infected through exposure to infected rodent body fluids (blood, saliva, urine), exposure to aerosolized rat excrement, or bites from infected rats.

Geographical Cluster
A geographical cluster is a localized anomaly, usually an excess of something given the distribution or variation of something else. Often it is considered as an incidence rate In epidemiology, incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time peri ... that is unusual in that there is more of some variable than might be expected. Examples would include: a local excess disease rate, a crime hot spot, areas of high unemployment, accident blackspots, unusually high positive residuals from a model, high concentrations of flora or fauna, areas with high levels of creative activity, physical features or events like earthquake epicenters etc... Identifying these extreme regions may be useful in that there could be implicit geographical associations with other variables that can be identified and would be of in ...

Hantavirus Hemorrhagic Fever With Renal Syndrome
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'' (vole fever) in Finnish, and ''musepest'' (mouse plague) in Norwegian. Both HFRS and hantavirus pulmonary syndrome (HPS) are caused by hantaviruses, specifically when humans inhale aerosolized excrements of infected rodents. Both diseases appear ...
