Introduction

Infection by feline herpesvirus (FHV), also known as feline viral rhinotracheitis (FVR), causes an acute-onset upper respiratory condition with flu-like symptoms that can lead to secondary bacterial infections in cats. This highly contagious disease can become life-threatening, especially in kittens. While there currently is no cure for FHV infection, there are treatments that can alleviate the painful symptoms and resolve any secondary bacterial infections that develop.

Treating Feline Herpesvirus

The treatment goals for cats with FHV infection are to stop viral replication, prevent or resolve secondary bacterial infections, relieve pain and minimize recurrence of clinical disease.

Many cases of FHV infection are self-limiting and resolve with little treatment other than supportive care. Affected cats often need nutritional and fluid support and may need to be force-fed and/or given intravenous or subcutaneous fluids. Dried nasal and ocular discharge should be removed gently with a warm, moist cloth. Topical broad spectrum antibiotic ointments are often prescribed to treat or prevent secondary bacterial infections. Affected cats should be isolated from other cats due to the highly contagious nature of this viral infection. They should be fed a highly palatable diet to prevent anorexia, subsequent weight loss and weakness. If possible, a humidifier or vaporizer should be placed in the isolation room to increase the moisture in the air. The cat’s environment should be kept calm and quiet so that rest is encouraged. Children in the household should be instructed to leave the cat alone until it is well. Recurrent infections should be treated swiftly and aggressively.

A number of new and promising treatments for FHV infections are under development. Talk with your veterinarian about appropriate treatment protocols if your cat is affected by this condition.
