Hendra Virus Infection in Dog, Australia, 2013

Abstract: Hendra virus occasionally causes severe disease in horses and humans. In Australia in 2013, infection was detected in a dog that had been in contact with an infected horse. Abnormalities and viral RNA were found in the dog’s kidney, brain, lymph nodes, spleen, and liver. Dogs should be kept away from infected horses.

“…Although some dogs developed subtle, non‐specific and short‐lived signs of infection, others remained clinically well throughout the period of virus replication; virus clearance was temporally associated with the development of virus neutralising antibody. These observations are consistent with the two canine field cases, in which neutralising antibodies against HeV were found in reportedly asymptomatic dogs that were tested during investigation of HeV events in horses and from which infectious virus was not recovered.…”

“…More recently, antibody to HeV has been found in asymptomatic dogs on two properties that were experiencing HeV outbreaks in horses . In at least one of those cases, the infected dog may have had exposure to the blood of an infected horse . The close relationship between dogs and people has raised a question regarding the potential of dogs to act as a source of transmission of HeV to people.…”

“…A second confirmed HeV infection in a dog was reported in 2013. The dog tested positive to HeV by quantitative reverse transcription PCR (q-RT-PCR) during the apparent early stages of an acute infection and had appeared to have become naturally infected with HeV following close exposure to blood from a euthanized HeV infected horse [35]. This dog was euthanized and extensively analyzed via postmortem examination.…”

“…Although the dog had appeared clinically healthy, histopathologic findings of widespread necrotizing vasculitis was noted, with the most severe lesions recorded in the kidney, brain and lymph nodes, with little involvement of the lungs. Additionally, HeV RNA was detected in multiple tissues [35]. Presently, the extent of HeV transmission from bats to dogs in Australia is an unknown concern and should be the focus of future studies.…”

“…2 Infected horses are further able to transmit HeV to other horses, dogs and humans, acting as an amplification host for the virus. 3,4 Clinical signs of HeV infection in horses are highly variable and non-specific, and infection has been confirmed in some cases in the absence of or with only minimal clinical signs, including, in some instances, a lack of pyrexia. 5 Acutely infected horses usually display depression and a range of general, respiratory and/or neurological signs, mediated by an endothelial vasculitis, such as fever, loss of appetite, abdominal pain, muscle fasciculations, terminal nasal discharge, ataxia and apparent loss of vision.…”
