    What is Rhino Flu?

    Rhino flu, also known as rhinopneumonitis in horses, is an upper respiratory disease caused by the equine herpes virus. It affects the mucous membranes of the nasal cavities and lungs. Although this disease is not life-threatening, it can cause serious health complications which affect the respiratory, reproductive and nervous system of the horse.

    What Causes Rhino Flu?

    Most adult horses are exposed to the equine herpes virus during their first months of life. The virus usually affects the horse’s respiratory system but remains dormant for the rest of his life with the help of the immune system.

    If the immune system is compromised in any way, the virus will cause respiratory symptoms. Rhino flu can also cause abortion in a pregnant mare if infected with the virus. The virus can also attacks the spinal cord and cause neurological symptoms. If treated early, symptoms can be reduced and managed.

    Diagnosing Rhino Flu

    The diagnosis of rhino flu is based on the symptoms, a complete physical examination and review of the horse’s medical history. Certain diagnostic tests such as x-rays, thoracic ultrasound, endoscopic examination, fine needle aspiration and lung biopsy may be performed to confirm the diagnosis.

    Symptoms and signs

    The common symptoms and signs of rhino flu include:

    • Fever
    • Loss of appetite
    • Lethargy
    • Nasal membranes and eyes redden and tear
    • Nasal discharge
    • Dry, hacking cough
    • Stocking up and heat in the lower legs
    • Swollen, enlarged lymph nodes in the neck


    Help for Rhino Flu

    Treatment of rhino flu involves certain medications, supportive care and adequate rest. Medications such as antibiotics may be prescribed to treat secondary infections. A vaccination program is very important to protect against infection.

    Pregnant mares require the rhinopneumonitis vaccine at least three times during the gestation period (months 5, 7 and 9) to prevent abortion. If your horse lives in isolation, an annual vaccination is usually sufficient.

    Young horses should also receive the vaccine every 2 to 3 months while horses that move around a lot should be vaccinated at least 4 times per year. These vaccinations, however, are not that effective and cannot protect against neurological disease.

    Avoid giving your horse human cough syrups or decongestants as these are potentially dangerous. In order to speed recovery, a comfortable, dry but well ventilated barn or stable, adequate rest, palatable foods as well as plenty of fresh, clean water and tender loving care are essential.

    Natural Remedies

    Natural and holistic remedies have also proven to be highly effective in providing symptomatic relief for upper respiratory diseases. Homeopathic treatments safely support the respiratory system in horses and also maintain overall health and well-being.

    Carefully selected ingredients such as Aconitum napellus, Belladonna and Hepar sulph are soothes the throat, clears congested noses and chests and strengthens the immune system. Silicea, Merc sol and Sulphur support respiratory health and acts as a tonic for the immune system.
