Symptoms of Feline Herpesvirus: What to Look Out For

Herpesvirus in cats is a common pathogen responsible for upper respiratory infections in felines, leading to a range of symptoms. Below is a detailed summary of the symptoms associated with feline herpesvirus:

Initial Symptoms of the Disease

These primarily manifest as upper respiratory infection signs: Affected cats often exhibit symptoms like coughing, sneezing, and runny nose, which can be easily mistaken for typical cold symptoms.

Eye and nose discharge: Initially, this is usually serous, but it may later become purulent.

Increased body temperature: Cats may experience a rise in their body temperature.

Other symptoms: Tears, frothy saliva, depression, and decreased appetite may also occur.

Intermediate Symptoms of the Disease

Eye symptoms: The eyes may become red and swollen, with purulent discharge, and some cats may have difficulty opening their eyes, a condition known as "crosseyed."

Systemic symptoms: Fever, decreased appetite, and rapid breathing, which can even lead to respiratory distress.

Other symptoms: Inability to tolerate exercise may also appear.

Advanced Symptoms of the Disease

Oral symptoms: Ulcers in the mouth, congested nasal mucosa, bloody nasal discharge, and ulcers on the tongue and mouth may occur.

Weight changes: Cats may experience weight loss, decreased appetite, and emaciation.

Severe Complications

1. Eye issues: Severe eye infections can lead to corneal ulcers, opacity, and even blindness.

2. Sinusitis: Chronic infection may result in sinusitis, characterized by persistent nasal congestion and discharge.

3. Chronic rhinitis: Repeated infections can lead to chronic rhinitis, with symptoms that may fluctuate in severity.

Treatment Recommendations

Should your cat display any of these symptoms, it is crucial to take them to a veterinary clinic for examination and treatment. A veterinarian may conduct the following checks:

1. Clinical examination: Observe symptoms and physical signs.

2. Laboratory tests: Collect nasal and throat swabs or blood samples for viral or bacterial cultures.

3. Imaging: In some cases, Xrays or CT scans may be necessary to assess lung conditions.

Treatment involves antiviral medications and antibiotics, including the administration of interferon, oral valacyclovir or acyclovir, and medications like Doxycycline hydrochloride tablets (Fronol).

【Important Notes】

‌Lifelong Carrier‌: Feline herpesvirus is a viral disease, and once a cat is infected, they carry the virus for life and may experience recurrences.

‌Contagious‌: The herpesvirus is highly contagious and can easily spread through nosetonose contact or sneezing, so infected cats should be isolated from others who have not been vaccinated.

In summary, the symptoms of feline herpesvirus are varied and can worsen over time. Therefore, timely diagnosis and treatment are essential. Seeking medical attention promptly and following the veterinarian's advice for treatment and supportive care can significantly increase the chances of recovery.
