Feline Herpesvirus 1 (FHV-1) is a common viral infection in cats, causing respiratory issues and eye problems. It is highly contagious among cats and can lead to symptoms like sneezing, nasal discharge, and conjunctivitis. FHV-1 is part of the Herpesviridae family and is often associated with stress or weakened immune systems. Once a cat is infected with FHV-1, the virus remains dormant in their body and can reactivate during times of stress. Vaccination can help reduce the severity of symptoms and the likelihood of outbreaks. Proper hygiene and minimizing stress are essential for managing this virus in feline populations.
