Ross River Virus in Horses

Ross River fever is a mosquito-borne viral infection, and is primarily known for affecting humans, but horses can also contract this disease. The Ross River virus (RRV) can cause significant health issues for horses, impacting their overall well-being and performance. In this post, we’ll explore what Ross River fever is, how it’s diagnosed in horses, its symptoms, and how nutrition can play a role in your horses recovery.

Ross River virus is spread through the bite of infected mosquitoes and is most prevalent in Australia. While the virus primarily affects humans, horses can also be infected, leading to symptoms similar to those seen in humans, such as fatigue, joint pain, and muscle soreness. In some cases, mild neurological symptoms can also present in the horse, significantly reducing a horse’s quality of life if not properly managed.

Horses with Ross River fever often present with symptoms such as:

Lethargy and general weakness

Swollen and stiff joints

Muscle pain or soreness

A reluctance to move or exercise

Low-grade fever

Mild neurological weakness in limbs

These symptoms can vary in severity depending on the horse’s immune response and overall health.

Diagnosing Ross River fever in horses typically involves blood tests to measure antibody titres, which indicate whether the horse has been exposed to the virus. Veterinarians will look for elevated levels of antibodies specific to the Ross River virus. While the acceptable titre levels can vary, a significant rise in antibody levels over time can confirm active infection. In some cases, horses may show high antibody levels even after recovery, making it important for veterinarians to consider clinical signs along with test results.

The virus primarily targets the musculoskeletal system, causing inflammation in the joints and muscles. This inflammation can make movement painful and challenging for horses. Additionally, the immune system may become compromised, leaving the horse more vulnerable to other infections during the course of the disease. Ross River can also effect our horses nervous system. The inflammation of nervous tissues can lead to dysfunction in the affected areas and the immune response generated by the body to combat the virus can sometimes inadvertently damage nerve cells, leading to neurological issues. The exact mechanisms of how the virus affects the nervous system are still being researched, but it is believed that the virus can cross the blood-brain barrier, contributing to CNS inflammation.

Recovery from Ross River fever can vary widely, with some horses recovering in a few weeks, while others may take several months to over a year to fully regain their strength, stamina and appetite. During this time, nutrition plays a crucial role in supporting the immune system and aiding in recovery. 𝐀𝐧𝐭𝐢𝐨𝐱𝐢𝐝𝐚𝐧𝐭𝐬 like curcumin, vitamin E and vitamin C can help reduce inflammation, while high-quality protein supports muscle repair.
