What Can You Do If Your Cat Has Feline Herpes Virus?

People always say "Prevention is better than cure." About 80% of cats have been exposed to FHV at some point in their life. It is difficult to prevent infections. Vaccination is available for FHV, however it is not 100% protective. Vaccinations can only help to reduce the severity of the cat flu and conjunctivitis. The normal 4-in-1 or 3-in-1 vaccination that your cat receives does cover FHV along with other viruses.

To attempt to lessen the severity of viral cat flu in cats, it is recommended that all kittens receive their three kitten vaccinations starting from 6 to 8 weeks of age and an adult booster vaccination 1 year after the last kitten vaccination. The subsequent booster vaccinations frequency can then be determined by the vet based on the risk of infection.

If there is low risk of infection by the viruses that the veterinarians vaccinate against, then it be best to give a booster vaccination every 3 years instead of yearly vaccinations.

Can I catch herpes from my cat?
No, only domesticated cats and their close relatives can catch Feline Herpes Virus.

Cat flu has many causes apart from FHV. Please seek veterinary attention should your cat develop cat flu and/or conjunctivitis. Do not attempt to self-medicate at the detriment of your cat or kitten.

What Are The Treatments For Feline Herpes Virus?

Like with most viral infections, a lot of the treatment is relied on the cat's own body immunity to fight the virus. The human antiviral medications used to treat human herpes viral infections can be used in cats but not without grave side effects and high costs. Therefore they are not routinely used unless in life-threatening situation.

The human alpha-interferon and a newer feline omega-interferon are alternative treatment drugs that may aid in the management of some cats. It is unlikely to lead to a cure but used only to try to lessen the severity of the clinical signs. Both are costly drugs with low success rates.

Some veterinarians would normally treat cats with suspected FHV-related cat flu or conjunctivitis with an oral L-Lysine supplement. L-Lysine is an amino acid (building block for protein) that has some antiviral properties and is very safe to use in cats with little or no side-effects at all.

It does not cure the cat of the virus but it helps to lessen the clinical signs of disease in the cat. In my opinion this is by far the best and most cost-effective "treatment" for FHV with favorable results obtained in many cats.

L-Lysine supplements come in several forms: from liquid syrups (usually together with other B vitamins in Children syrups) to tablets (GNC Lysine tablets) and recently a newly introduced paste form (Enisyl-F) specially formulated for cats have been introduced in many veterinary clinics.

If there is severe conjunctivitis or greenish nasal discharge, topical antibiotic eye drops or oral antibiotics may be prescribed concurrently. L-Lysine supplementation is also recommended in times of stress or illness even if the cat does not show signs of cat flu or have an eye problem yet.

Is There Any Cure For Feline Herpes Virus?

Unfortunately, there is no effective cure for FHV in the cat. There is a saying that says: "Herpes is forever!" Like in the human, once infected, a cat can either eliminate the virus from the body, or it becomes a carrier and lives with the virus for life. This virus enters and hides in the nerve systems of the cat, thus protecting it from being killed by the cat's immune system. There it stays dormant in the nerves until in times of illness or stress, when the body's immune system is suppressed, the virus then resurfaces to cause disease.

Your cat will subsequently either start sneezing again or get its eye problem back. It is through this clever mechanism that FHV results in chronic recurrent cat flue or eye problems. Cats have an increased risk of becoming carriers if they are infected at a young age before they have vaccination immunity or mature immune systems.

What Is Feline Herpes Virus Infection?

Feline Herpes Virus of FHV is one of the most common viruses infecting cats all around the world. The word "herpes" brings a shudder to many people as we immediately think of genital warts or cold sores in our human counterparts. Do not panic for your beloved cats as these feared disease conditions do not occur in the cat.

Instead, FHV is one of the two most common viral causes of the cat flu and conjunctivitis (eye infection) in our feline friends. Affected cats often present with sneezing, nasal discharge and can have concurrent conjunctivitis. The virus usually affects only one eye in the cat. Corneal ulcers may also be present in the affected eye. These clinical signs of a FHV infection can range from being very mild to very severe and may be self-limiting in some cats. The more severe clinical signs are often seen in the young and old cats with compromised immune systems.

Diagnosis of FHV cannot be confirmed through routine diagnostic tests like a blood test. The virus may be documented by testing conjunctival samples through complicated laboratory testing however these diagnostic tests are not available in some cities. Therefore diagnosis of a FHV infection in the cat is often one of a presumptive diagnosis based on history and clinical signs.
