Orange Vet Hospital are sharing our concern for an increased risk of Hendra occurring in the horse population across the Orange and Central West region.
Winter 2020 may present a higher risk for Hendra infection in horses due to current climate patterns which appear to make spillover events more likely. Similar patterns were seen in winters of 2011 and 2017, both years of significant increase in Hendra cases.
“Hendra virus is carried by flying foxes which excrete the virus most commonly during winter. If horses come in contact with the excretions they can become infected and then shed massive amounts of virus which can infect and kill humans” says OVH vet Andrew Litchfield.
Symptoms of the virus include a rapid onset of illness, fever, sweating, increased heart rate and rapid deterioration with respiratory and/or neurological (nervous system) signs. Signs that horse owners could easily attribute to a severe colic event.
“Horses most commonly become infected by consuming food or water contaminated by faeces and urine from flying foxes. Infected horses shed large amounts of virus via the nose, mouth and faeces even prior to becoming sick putting other horses and humans at risk”.
To prevent infection, ensure that horses are not kept near flying fox roosts. Feed and water sources need to be carefully managed so that contamination is avoided. Biosecurity is essential for horses travelling off their property.
A vaccine for horses is available from Orange Vet Hospital and is strongly encouraged as the single most effective way to reduce the risk of Hendra virus infection. We urge horse owners to be aware of the risk and consider vaccination in order to protect their horses and themselves.
“We encourage horse owners to contact the Hospital if they notice unusual disease symptoms, abnormal behaviour or unexpected deaths in their horses.”
The following infographic will assist in horse owners keeping up to date with vaccinations.
