The Hendra virus (HeV) is a zoonotic infection. It is a member of the Henipavirus genus (family Paramyxoviridae, order Mononegavirales). It belongs to the same genus as Nipah virus, another zoonotic pathogen. HeV is genetically and antigenically related to Nipah virus, with which it shares more than 90% amino acid homology. HeV was discovered during the first recorded outbreak of the disease in 1994 in the Brisbane suburb of Hendra, Australia. HeV infections in horses and humans have occurred in Australia since then. The flying fox (fruit bat) is the natural host for HeV, but they do not show any symptoms of illness when infected. HeV can occasionally be transmitted from flying foxes to horses. It causes fatal acute respiratory and/or neurologic symptoms, which usually result in death. People and dogs have been infected as a result of close contact with clinically infected horses on rare occasions.

Structure of Adenovirus

HeV virion is an enveloped, spherical-to-filamentous virus with a diameter of 40-600 nm and a length of 1900 nm. HeV genomes are 18.2 kb in size and are non-segmented, single-stranded, negative-sense RNA. Six structural proteins are encoded by the genome: fusion protein (F), attachment protein (G), matrix protein (M), nucleocapsid protein (N), large protein (L), and phosphoprotein (P). G and F glycoproteins, two membrane-anchored surface glycoproteins, mediate viral attachment and fusion to the host cell. P and L proteins aid in the transcription of the viral genome. Nonstructural proteins encoded by HeV P genes include V protein, W protein, and C protein. The P, V, W, and C proteins have been shown to inhibit the immune host response and act as virulence factors.

It is believed the virus can be transmitted from:

  • Flying fox to horse. Horses may be infected after exposure to the virus in the secretions of infected flying foxes. However, the precise way in which this occurs is not known.
  • Horse to horse. Horse to horse transmission is inefficient, requiring direct contact with infected body fluids
  • Horse to dog. Dog may be infected by close contact with a living or dead horse that is infected with the virus.
  • Horse to human. Transmission of HeV to humans can occur after exposure to body fluids and tissues or excretions of horses infected with HeV.

There is no evidence of human-to-human, human-to-horse, or human-to-horse transmission.
