Causes
Canine herpesvirus belongs to the Herpesviridae family and is closely related to other herpesviruses found in various animal species. Herpesviruses are DNADNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for the development, function, and reproduction of all known living organisms and many viruses. It is located in the cells of an organism and contains the information for heredity. viruses known for their ability to persist in the host for life. After an initialInitial means beginning or at the start. In medicine, it can refer to the first symptoms of a disease or the first phase of a treatment process. infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles.

In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. or immunosuppressionImmunosuppression is a state of reduced activity or effectiveness of the immune system. In dogs and cats, immunosuppression can occur naturally or be caused by certain medications, diseases, or medical treatments..
CHV is highly contagiousContagious means infectious. Diseases that can easily be transmitted from one animal to another or from animals to humans are referred to as contagious. and is mainly transmitted through direct contact between dogs or through contact with contaminatedContaminated describes something that has been polluted by harmful microorganisms, chemicals, or other dangerous substances. In veterinary medicine, this can affect food, water, toys, or the environment. surfaces and objects. One of the main causes of the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. spreading is the contact of pregnant bitches with infected dogs, which can lead to transmission to the puppies.
In newborn puppies, whose immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. is not yet fully developed, the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. can quickly cause life-threatening infections. The risk of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is particularly high in the first weeks of life. Adult dogs can carry and spread the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. without showing serious symptoms themselves, which makes controlling the disease difficult.
Symptoms
Symptoms of a CHV infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. can vary depending on the age and health of the dog. In newborn puppies, symptoms are often severe and can appear suddenly. The most common signs include loss of appetite, respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, abdominalThe term “abdominal” refers to anything that concerns the belly or the abdomen. It is an adjectival expression used to describe the location, symptoms, or conditions that occur in the abdominal area. pain, and weakness. Puppies may also develop a bluish discoloration of the mucous membranes and skin, a condition known as cyanosisCyanosis refers to a bluish discoloration of the skin and mucous membranes, caused by an inadequate oxygen supply to the blood. It can be a sign of heart, lung, or blood diseases..
In older puppies and adultThe term “adult” refers to an individual who has reached full physical development and is considered an adult. In veterinary medicine, this term is used to describe animals that have completed growth and are of reproductive age. dogs, the symptoms are often milder. They may develop respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. diseases that manifest as cough, sneezing, and nasalNasal refers to the nose and nasal cavities. In veterinary medicine, this can involve examinations, treatments, or diseases affecting the nose of dogs and cats. discharge. Some dogs may also develop eye diseases or skin lesions. In many cases, however, older dogs show no or only very mild symptoms.
Key symptomsKey symptoms are the main or characteristic symptoms of a disease that are particularly important for the diagnosis. They help to distinguish a specific condition from others with similar symptoms.: sudden death of puppies in litters with gastrointestinalGastrointestinal refers to the gastrointestinal tract, a system that extends from the oral cavity to the anus and is responsible for the digestion of food and the absorption of nutrients. and respiratoryRespiratory refers to breathing or the process of breathing.

Heat and hygiene management in the whelping box are crucial, as the virus is sensitive to cold.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of a CHV infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is based on a combination of clinical signs, medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits., and special laboratory tests. If a CHV infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is suspected, a veterinarian can take samples of affected tissues or fluids to detect the presence of the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants..
Laboratory tests such as polymerase chain reaction (PCR) can be used to confirm the genetic presence of the virus. Serological tests can also be used to detect antibodies against the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. in the blood, which can indicate a past or current infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. An accurate diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is important for planning the appropriate therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. and preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. strategies.
Therapy
Unfortunately, there is no specific antiviral therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. that can completely cure CHV. Treatment therefore focuses on supporting affected dogs and alleviating symptoms. Intensive care may be required for newborn puppies, including heat support, hydration, and, if necessary, the administration of antibiotics to prevent secondary bacterial infections.
In older dogs showing respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. symptoms, treatment may include medication to relieve cough and nasal discharge, as well as support for the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body.. It is important to isolate infected dogs from other animals to prevent the spread of the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants..
Prognosis and follow-up care
The prognosis for newborn puppies with CHV infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is often poor, especially if the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is not detected and treated early. Many infected puppies die within a few days of symptoms appearing. In older puppies and adultThe term "adult" refers to an individual who has reached full physical development and is considered an adult. In veterinary medicine, this term is used to describe animals that have completed growth and are of reproductive age. dogs, the prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. is better as they develop less severe symptoms and often recover completely.
However, dogs that survive a CHV infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. can carry the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. for life and develop symptoms again in stressful situations. Therefore, long-term monitoring and care are necessary to minimize the risk of reactivation.
Prevention
PreventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of CHV infections is mainly based on controlling the spread of the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. and protecting vulnerable animals. One of the most important measures is avoiding contact between infected and non-infected dogs, especially during pregnancy and after birth.
Hygiene measures, such as regular cleaning and disinfection of kennels and equipment, can also help minimize the spread of the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants.. In some countries, vaccines against CHV are available that can be used in pregnant bitches to promote immunity against the virusA virus is a microscopic infectious particle that cannot reproduce on its own and must infect a host cell to produce new virus particles. Viruses can cause a variety of diseases in humans, animals, and plants. and reduce transmission to the puppies.
Special care should be taken when introducing new dogs into existing groups or breeding facilities to ensure that they are free of CHV. Regular veterinary monitoring and health checks can also help to detect and control potential outbreaks early.
