Risk associated with herpes simplex virus infection on dogs
What causes Alzheimer's disease? The answer could be right under our noses, says leading expert Professor Ruth Itzhaki. Her latest paper presents a lifetime of research evidence that the herpes virus responsible for cold sores can also cause Alzheimer's -- and new data which show antiviral drugs drastically reduce risk of senile dementia in patients with severe herpes infections. The review in Frontiers in Ageing Neuroscience raises the tantalizing prospect of a simple, effective preventive treatment for one of humanity's costliest disorders. Herpes in are the dreaded 'gift that keeps on giving'. They remain lifelong in our neurons and immune cells, reactivating and resurfacing in characteristic blisters when we're run down by stress or illness. HSV1 is better known as the cause of cold sores.
Puppies usually contract the disease in the birth canal or from nasal and oral secretions of the mother shortly after birth. Puppies can also spread the virus to one another.
What Are the Symptoms of Canine Herpes in Adult Dogs?
Just because one puppy in a litter is infected with CHV does infction mean they all are. If a puppy is stillborn or dies soon after birth, a necropsy should be performed to determine the cause of death. There are many potential causes for puppy death, and you will want to evaluate whether the rest of the litter is at risk and what care is needed.
Please call your veterinarian for instructions on how to arrange this.

Adult dogs are generally tested for CHV if they are intended for breeding or if their history suggests a problem with CHV. A veterinarian may check bloodwork to attempt to confirm recent exposure to the virus. If CHV is confirmed, treatment can begin with antiviral medication and supportive care.
It infectlon also important to keep puppies warm, as the virus requires a low temperature to survive.
Unfortunately, death often occurs rapidly in CHV-infected puppies despite good care. CHV is a common virus that many adult dogs come into contact with. The best way to combat this disease in young puppies is through preventing exposure.

It is important to isolate a pregnant female from other dogs during the high-risk period--both late in her pregnancy and during the first three weeks after birth. They remain lifelong in our neurons and immune cells, reactivating and resurfacing in characteristic blisters when we're run down by stress or illness. HSV1 is better known as the cause of cold sores.
Few countries collect the population data required to test this theory -- for example, to find out whether antiviral treatments reduce dementia risk. In Taiwan however, researchers have done just that. There, In three studies were published describing Taiwanese data on the development of simplexx dementia -- of which Alzheimer's is the main cause -- and the treatment of patients with marked overt signs of infection with HSV or varicella zoster virus VZV, the chickenpox virus.
Canine Herpes Virus: Symptoms, Treatment, and Vaccination
Previous findings from Itzhaki's own research group provide a mechanistic link which supports these epidemiological findings. They found that HSV1 causes protein deposits characteristic of Alzheimer's: 'plaques' between neurons, and 'tangles' inside of them.Aug 06, · A nonpathogenic strain of human herpes simplex virus 1 was injected into the brains of normal dogs, establishing a latent infection with no pathologic changes. 54 Equine herpesvirus 9 is a neurotropic virus that infects horses. Herpes simplex virus type 2 (HSV-2) has been shown to increase the risk of sexual human immunodeficiency virus (HIV) transmission. A matched case-control design was used to examine the association between HSV-2 and HIV infection among heterosexuals in ‘high-risk areas’ (HRAs) in New York City (NYC). Background Herpes simplex virus type 2 (HSV-2), the primary cause of genital herpes, is one of the most prevalent sexually transmitted diseases worldwide. Epidemiologic serosurveys suggest that infections occur more frequently in women than in men. Goal .
The main proteins of both plaques and tangles accumulate also in HSV1-infected cell cultures -- and antiviral drugs can prevent this. Although further work is needed to confirm and define a causal link between HSV1 infection and Alzheimer's, Itzhaki is enthusiastic about the treatment prospects. This echoes the growing use worldwide of human papillomavirus HPV vaccination to prevent cervical cancer -- another virus-disease link which emerged in a similar process of research.

While adult dogs infected with CHV usually do not show any symptoms, the infection is the leading cause of death in newborn puppies. One puppy in a litter may be affected, and death may occur abruptly, with little or no warning, or an entire litter may perish within a hour period.
