Hendra virus (HeV) is an emerging zoonotic paramyxovirus for which natural reservoirs are the 4 species of flying fox ( Pteropus bats) found on mainland Australia ( 1 ). (cdc.gov)
The grey-headed flying-fox (Pteropus poliocephalus) is the largest member of the family and is a native species that is endemic to Australia on the eastern seaboard - southern Queensland, New South Wales and Victoria. (jeadvm.com)
Also, Pteropus bats (fruit-eating species, popularly known as flying foxes) are supposed to be the natural hosts of the virus. (jagranjosh.com)
Bats10
Nipah virus and Hendra virus are closely related paramyxoviruses that emerged from bats during the 1990s to cause deadly outbreaks in humans and domesticated animals. (wikipedia.org)
Hendra virus is believed to be partially seasonally related, and there is a suggested correlation between breeding time and an increase in the incidence of Hendra virus in flying fox bats. (wikipedia.org)
The two most recent outbreaks of Hendra virus in 2011 and 2013 appear to be related to an increased level of nutritional stress among the bats as well as relocation of bat populations. (wikipedia.org)
According to the World Health Organisation (WHO), the virus is thought to naturally infect fruit bats but it can also infect pigs and other domesticated animals like dogs, cats, goats etc. (jagranjosh.com)
Nipah Virus is transmitted to humans through direct contact with infected bats, infected pigs or other NiV-infected people. (jagranjosh.com)
In Malaysia and Singapore, humans are infected with Nipah Virus only through close contact with infected pigs which came in contact with the bats that had lost their habitats due to deforestation. (jagranjosh.com)
The disease spreads through fruit bats or flying foxes who are natural reservoir hosts of the Nipah and Hendra Viruses. (jagranjosh.com)
In Bangladesh and India, this virus is transmitted from bats while drinking raw palm sap contaminated with bat excrement or climbing trees coated in the same or through a virus-infected person. (jagranjosh.com)
Bats are the main reservoirs of the virus, and different clinical courses have been described in humans. (bvsalud.org)
The vaccine is a subunit vaccine that neutralises Hendra virus and is composed of a soluble version of the G surface antigen on Hendra virus and has been successful in ferret models. (wikipedia.org)
Infection caused by to Nipah virus is an emerging disease and till now there is no drug to treat the illness and no vaccine to prevent it. (jagranjosh.com)

During 1994-2010, there were a total of 14 HeV outbreaks, including those with the 7 human infections. (cdc.gov)
Among the most notable are the henipaviruses, which include the deadly Nipah (NiV) and Hendra (HeV) viruses, the causative agents of outbreaks of severe disease and high case fatality rates in humans and animals. (bvsalud.org)
Closely related2
The organism which causes Nipah Virus (NiV) encephalitis is an RNA or Ribonucleic acid virus of the family Paramyxoviridae, genus Henipavirus, and is closely related to Hendra virus. (jagranjosh.com)
We also highlight the emerging threats posed by these and potentially other closely related viruses. (bvsalud.org)
Infection8
Symptoms of Hendra virus infection of humans may be respiratory, including hemorrhage and edema of the lungs, or in some cases viral meningitis. (wikipedia.org)
A seroprevalence of 47% is found in the flying foxes, suggesting an endemic infection of the bat population throughout Australia. (wikipedia.org)
however, in humans and horses there is evidence of initial virus replication in the nasopharynx that progresses through a viremic phase during which the virus spreads to major organ systems, resulting in disseminated endothelial cell infection, vasculitis, encephalitis, and pneumonia ( 4 - 7 ). (cdc.gov)
Nipah Virus: Nipah Virus causes severe infection in humans and animals and get its name from the village of Malaysia where first time it was first identified. (jagranjosh.com)
This infection can affect human beings and the virus can also spread from person to person. (jagranjosh.com)
Hendra virus causes infection in horses and then in humans which was first reported in Australia in 1994 . (jagranjosh.com)
Humans7
Trials began in 2015 to evaluate a monoclonal antibody to be used as a possible complementary treatment for humans exposed to Hendra virus infected horses. (wikipedia.org)
For example, Hendra virus (HeV), a zoonotic paramyxovirus, was discovered in 1994, and since then, infections have occurred in 7 humans, each of whom had a strong epidemiologic link to similarly affected horses. (cdc.gov)
HeV was discovered in 1994, and since then, infections have occurred in 7 humans, 4 of whom died. (cdc.gov)
Humans contract the virus through close contact with infected horses. (jeadvm.com)
Paramyxoviruses are a family of single-stranded negative-sense RNA viruses, many of which are responsible for a range of respiratory and neurological diseases in humans and animals. (bvsalud.org)
Recently, non-chiropteran associated Langya (LayV), Gamak (GAKV), and Mojiang (MojV) viruses have been discovered with confirmed or suspected ability to cause disease in humans or animals. (bvsalud.org)
They are also of interest to those involved in public health as they are natural reservoirs of several viruses that can affect humans. (wikipedia.org)
Scientists call that the reservoir of the virus, it's the organism that keeps the pathogen alive. (jeadvm.com)
Recent advances in surveillance of wild animal reservoir viruses have revealed a high number of henipaviral genome sequences distributed across most continents, and mammalian orders previously unknown to harbour henipaviruses. (bvsalud.org)
Outbreak2
Hendra Virus wasn't discovered until 1994, when the first outbreak occurred in Hendra, Queensland. (jeadvm.com)

Horses5
Horses become infected with Hendra after exposure to bodily fluid from an infected flying fox. (wikipedia.org)
Hendra virus (originally called "Equine morbillivirus") was discovered in September 1994 when it caused the deaths of thirteen horses, and a trainer at a training complex at 10 Williams Avenue, Hendra, a suburb of Brisbane in Queensland, Australia. (wikipedia.org)
Experimental exposure of horses to HeV/Australia/Horse/2008/Redlands under Biosafety Level 4 (BSL-4) conditions identified comparatively low gene copy numbers in nasal secretions early in the incubation period. (cdc.gov)
This risk is then exacerbated because it is symptomatic horses that come to the attention of veterinarians, leading to various clinical investigations (e.g., respiratory tract endoscopy) that may facilitate human exposure to virus. (cdc.gov)
The virus may be transmitted from flying-foxes to horses via exposure to urine or birthing fluids. (jeadvm.com)
