Feline Herpesvirus Type-1 (FHV-1) is a highly contagious virus that causes feline viral rhinotracheitis (FVR)—a major cause of upper respiratory infections in cats. It primarily affects the eyes, nose, and throat.
Chronic or recurrent eye issues like corneal ulcers or scarring are common in long-term FHV infections.
How to Prevent Feline Ocular Herpesvirus in Cats
Vaccinate: The FVRCP vaccine helps protect against FHV-1.
Isolate new or sick cats
Reduce stress in multi-cat households
Maintain good hygiene with food bowls, bedding, and litter
How Do Cats Contract Feline Herpesvirus?
It is estimated that 95% of all cats carry FHV-1. The virus is spread through:
Direct contact with infected cats (most kittens acquire the virus from their mother)
Sneezing/coughing droplets
Sharing food bowls, bedding, or litter boxes.
Feline Herpesvirus is not contagious to humans or dogs.
Diagnosis & Treatment
Diagnosis is based on clinical signs, history, and sometimes lab testing. Our goals in treating herpes virus infections are to decrease the expression of the virus at the ocular surface, prevent secondary bacterial infections, and improve comfort.
