Understanding Feline Viral Rhinotracheitis (FVR) and Calicivirus

Feline Viral Rhinotracheitis (FVR) and feline calicivirus are highly contagious viruses causing feline upper respiratory infections (URIs). FVR, caused by the feline herpesvirus type 1 (FHV-1), often presents with sneezing, nasal discharge, and eye inflammation. Calicivirus infections share similar symptoms but can also cause oral ulcers and lameness in severe cases.

Diagnosing FVR and Calicivirus

Veterinarians diagnose these infections through clinical signs and sometimes PCR testing. PCR provides definitive identification, crucial for treatment strategies. While amoxicillin treats secondary bacterial infections, it’s ineffective against viruses. Therefore, supportive care focuses on managing symptoms.

Treating Feline URIs

Treatment emphasizes hydration, which can be achieved through subcutaneous fluids if necessary. Antiviral medications can reduce the severity and duration of FVR and, in some cases, calicivirus infections. Pain management is also important, especially for animals with oral ulcers. Eye drops or ointments might relieve eye irritation. Regular veterinary checkups are key for monitoring progress and addressing complications. Good hygiene practices in the household, including disinfection, prevent transmission.
