Seven confirmed Hendra virus infections in humans, all in Queensl… Nipah Virus (NiV) or Hendra virus is a deadly virus that spreads via contact with the saliva, urine, or excreta of fruit bats or pigs. Cedar Virus has been shown to infect ferrets and guinea pigs and initiate an immune response by the host to the virus… Much like Nipah, the closely-related Hendra virus was also discovered in the 1990s in Australia where it repeatedly causes fatal infections in horses and exposure risk to people. The It can be fatal. Hendra virus (HeV) is a serious, potentially fatal virus that is spread from flying foxes to horses, and from infected horses to humans. A vaccination to help prevent this condition was created in 2012. Hendra virus symptoms in human are: The symptoms start appearing in 5-21 days of infection with the virus or after coming in contact with the infectious horse Fever, cough, sore throat, headache, and tiredness Meningitis or encephalitis can develop causing headache, high fever, drowsiness, and sometimes convulsions and coma Clinical signs are highly variable but usually have a very rapid, acute onset and range from mild to severe. To date, there have been seven confirmed human cases of Hendra Virus. Hendra virus, scientific name Hendra henipavirus, is a bat-borne virus that is associated with a highly fatal infection in horses and humans. Although all human cases of HeV infection have stemmed from close exposure to Hendra‐infected horses, horses are not the reservoir of the virus, instead, they are simply incidental hosts, as are humans. Aust Vet J 76 (12), 813-818 PubMed. Rev Sci Tech 19 (1), 151-159 PubMed. The virus occurs naturally in flying fox (bat) populations, and it is thought to be transferred to horses through contaminated urine, feces, or fetal fluids. Hendra virus (HeV) was first isolated in 1994 in horses at a racing stable in Hendra, Brisbane. Humans can become infected by coming into contact with infected horse bodily fluids such as urine, faeces, blood and nasal secretions. Hendra virus is the type species of Henipavirus. Signs consistent with colic have been the initial sign described in many cases. Hendra virus causes vague symptoms early in infection such as restlessness, depression and fever.

In meningitis and encephalitis, symptoms may involve a headache, drowsiness or fever leading to coma and death. J Gen Virol 2000; 81: 1927-1932. Abstract. The clinical syndrome associated with Hendra virus infection in horses was predominantly associated with Hendra Virus (Australian Hendra Virus): Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis. The natural reservoir of these viruses are pteropid fruit bats. 1 HeV, formerly called equine morbillivirus, was first described after an outbreak of severe respiratory disease in horses, leading to the deaths of 14 horses and a horse trainer in Brisbane in September 1994. The virus can be spread by infected horses for up to three days before they show any clinical signs of infection. Hendra virus infection in horses can produce a wide range of signs and is often difficult to recognise. The natural host for Hendra virus is the flying fox. The incubation period for Hendra virus in horses ranges from 5 to 16 days. This horse developed Hendra virus was discovered following an outbreak of illness in a large racing stable in the suburb of Hendra, Brisbane, Australia in 1994. Westbury H A (2000) Hendra virus disease in horses. Depression. Hendra Virus is a deadly disease with symptoms that mimic those commonly seen during a colic episode. Hendra virus (HeV) is a paramyxovirus (genus Henipavirus) that causes respiratory and neurologic disease in horses and humans; the case-fatality rate is >60%.Fruit bats are the reservoir hosts (2,3) and excrete virus in urine ().Disease outbreaks among horses occur sporadically along the eastern coast of Queensland and New South Wales, Australia. Since 1994 and as of 2013, Hendra virus infections in humans remain rare; only seven cases have been reported. Hendra virus is endemic in Australia. This virus is a member of the Henipavirus genus and related to Hendra virus, from a similar genus. It is related to Nipah virus, another species in the genus Henipavirus. Hendra virus (HeV), previously known as equine morbillivirus, emerged as a lethal zoonotic virus almost 20 years ago.

Since 1994, there have been only 7 cases of Hendra virus infecting humans after exposure to sick horses. A more recent addition to the family is a virus called Cedar Virus. HeV was first isolated in 1994 from specimens obtained during an outbreak of respiratory and neurologic disease in horses and humans in Hendra, a suburb of Brisbane, Australia. Nipah virus is mostly used in these humans who have a high range of infection which does not have any symptoms; it is an acute respiratory disorder and can also be fatal. Hendra virus is a fragile RNA virus which does not survive for very long (hours or days) outside the animal host. Humans can become infected by being exposed to infectious fluids, like lung exudates, urine, blood, and tissues. Hendra virus (originally Equine morbillivirus) was discovered in September 1994 when it caused the deaths of thirteen horses, and a trainer at a training complex in Hendra, a suburb of Brisbane in Queensland, Australia. Hendra virus should be considered in any unwell horse when the cause of infection is unknown and especially in which symptoms and symptoms development brief with fast deterioration. Nasal discharge (clear, white or blood stained) Head tilting or circling. Hendra virus is an emerging zoonotic virus, which means that it can transfer from animals to people. Virus shedding from these bats appears Williamson M Met al (1998) Transmission studies of Hendra virus (equine morbillivirus) in fruit bats, horses and cats. The viral agent is endemic in specific species of fruit bats (also called flying foxes), and close contact with these bats is suspected to have facilitated transfer of the HeV to horses.
