Herpesviral ocular disease is highly prevalent, resulting predominantly from animal to animal contact, frequently via aerosolization of sneezed particles. Affected animals may display a range of symptoms including sneezing, coughing, nasal discharge, pyrexia, inappetance, lethargy, conjunctivitis, chemosis, keratitis and/or secondary corneal ulceration. Young kittens are generally most severely affected, immune-competent adult cats generally exhibiting less severe symptoms. Feline patients may additionally be infected with secondary pathogens including calicivirus, chlamydophila felis, mycoplasma sp. and/or bacterial pathogens.
