1. What Is Feline Herpesvirus (FHV) in Cats?
Yes, feline herpesvirus (FHV), specifically FHV-1, is a common virus affecting cats, primarily causing upper respiratory infections. According to research from the Cornell Feline Health Center, FHV-1 is highly contagious among cats, especially in shelters or multi-cat households. Understanding FHV helps cat owners provide better care and management for their feline companions.
FHV, or feline herpesvirus, is also known as feline viral rhinotracheitis (FVR). It’s a viral infection that primarily affects the upper respiratory system of cats, causing symptoms similar to a common cold in humans. This virus is widespread in the cat population, and once a cat is infected, it often becomes a lifelong carrier.
1.1. What Causes Feline Herpesvirus?
Feline herpesvirus is caused by the FHV-1 virus. Cats contract it through:
- Direct Contact: Coming into contact with saliva, nasal or eye secretions from an infected cat.
- Indirect Contact: Sharing food bowls, litter boxes, or bedding with an infected cat.
- Aerosol Transmission: Inhaling virus particles in the air, though this is less common.
1.2. How Common Is Feline Herpesvirus?
FHV is highly prevalent among cats. Studies suggest that up to 80% of cats have been exposed to FHV-1. However, not all exposed cats develop active infections or show symptoms. Many cats become latent carriers, meaning the virus remains dormant in their bodies and can reactivate under stress.
2. What Are the Symptoms of Feline Herpesvirus?
What are the symptoms of feline herpesvirus? Common symptoms of FHV include sneezing, nasal discharge, and conjunctivitis, but can vary in severity. Early detection and management of these signs, as outlined by the American Animal Hospital Association (AAHA), are crucial for improving your cat’s comfort and preventing complications.
The symptoms of feline herpesvirus can vary in severity, depending on the cat’s age, immune system strength, and overall health. Here are some of the most common signs:
- Sneezing
- Nasal Congestion and Discharge
- Conjunctivitis (Inflammation of the Conjunctiva)
- Excessive Tearing
- Squinting
- Fever
- Loss of Appetite
- Lethargy
- Coughing (Less Common)
- Oral Ulcers (Rare)
- Dermatitis (Skin Inflammation)
2.1. What Are the Stages of FHV Infection?
The infection typically progresses through several stages:
- Incubation Period: After exposure, there’s an incubation period of 2-5 days before symptoms appear.
- Active Infection: Symptoms usually last for 10-20 days. During this phase, the cat is highly contagious.
- Latency: After the active infection subsides, the virus becomes dormant in the nerve cells.
- Reactivation: The virus can reactivate due to stress, illness, or other triggers, causing recurrent symptoms.
2.2. Can FHV Cause Other Complications?
Yes, FHV can lead to several complications:
- Corneal Ulcers: FHV can cause painful ulcers on the cornea, the clear front part of the eye.
- Eosinophilic Keratitis: This chronic inflammatory condition affects the cornea, causing white or pink lesions.
- Pneumonia: In severe cases, FHV can lead to pneumonia, especially in young kittens.
- Secondary Bacterial Infections: FHV can weaken the immune system, making cats more susceptible to secondary bacterial infections.
