Suid Herpesvirus in Dogs
Suid Herpesvirus in Dogs, also known as pseudorabies virus infection, is a rare yet highly lethal disease observed in dogs, particularly those in contact with swine. Unfortunately, many dogs infected with this virus succumb suddenly, often without displaying distinct symptoms.
When signs do manifest, they typically include heightened salivation, intense itching, and alterations in neurologic behavior. Due to the severe itching it induces, pseudorabies is colloquially termed as “mad itch.”
The virus can infect both dogs and cats, particularly those residing on farms, as well as other domestic animals such as swine, cattle, sheep, and goats. Notably, there are no specific breed, gender, or age tendencies associated with this viral infection..
Symptoms and Types
As mentioned earlier, a dog afflicted with pseudorabies may exhibit no symptoms whatsoever. However, potential signs to watch for include:
- Fever
- Vomiting
- Excessive salivation
- Rapid and difficult breathing
Neurological symptoms may also manifest, including:
- Depression
- Lethargy
- Ataxia
- Convulsions
- Reluctance to move
- Excessive lying down
- Intense itching and self-inflicted injuries from scratching
Causes
Apart from direct exposure to swine, dogs can acquire the pseudorabies virus (Suid herpesvirus 1) through the consumption of contaminated, raw meat or organs from swine, or by ingesting rats that are infected.
Diagnosis
The diagnosis of pseudorabies virus infection in your dog will be conducted by your veterinarian, who will differentiate it from diseases presenting similar symptoms. For instance, dogs affected by typical rabies exhibit aggressive behavior towards moving objects, without experiencing itching or sudden death. Conversely, poisoned dogs show no signs of itching or personality alterations. In cases of canine distemper, symptoms such as hypersalivation, sudden death, or personality changes are absent, although respiratory and gastrointestinal indications are prevalent.
If your dog successfully recovers from the infection, pseudorabies virus antibodies will be detected through a blood test. In the event of sudden death, your veterinarian will examine the brain tissue to confirm pseudorabies.
Treatment
Regrettably, there are no viable medical or pharmaceutical treatments available for the pseudorabies virus at present.
Living and Management
Expected progression and prognosis:
- Classic Form of the Infection: In approximately 60 percent of cases, the illness persists for 24 to 36 hours, resulting in nearly inevitable fatality.
- Atypical Form of the Infection: In about 40 percent of cases, the illness lasts beyond 36 hours, leading to nearly inevitable fatality.
- There exists a slight risk of human infection. Caution should be exercised when treating affected animals and when handling contaminated tissues and fluids. Transmission between dogs is uncommon.
Prevention
- Steer clear of contact with infected swine, which serve as the reservoir host.
- Refrain from consuming contaminated pork.
- Avoid ingesting infected rats.
