Canine Parvovirus- A Strong Virus that can survive almost anywhere.
The first time I heard about parvovirus was years ago when my friend's pet was diagnosed and she had to take him for treatment, the vet informed us that the chances of survival are usually 50/50 and she was so scared, but her pet survived amongst other pet and she even had to tip the vet after making full payment. Today, while we improve our study on the knowledge of the health of our pets, we will be exploring the topic, Canine Parvovirus.
Canine Parvovirus, the addition of canine to the disease name is significant because this virus affects humans too, but it is not spread from animal to humans, if time permits, I will touch that briefly before I round up the post but if not, we may have to discuss the topic some other day, back to the topic of the day. Canine Parvovirus is a very contagious virus that can affect all dogs, unvaccinated dogs as well as puppies younger than 4 months in age stand a higher chance of contracting the virus. When a dog is ill from canine parvovirus infection, it is said to be parvo. The virus affects the gastrointestinal tract of the dog and it spreads through a form of direct dog-dog contact, contact with contaminated stool, contaminated environment, and even contaminated humans. Once the virus is around the corner, it can contaminate the bowls, food, and water of the pet, collars, and leashes are also not exempted.
The virus is resistant to cold, heat, humidity, and drying, therefore it can conveniently survive in an environment for a very long time. Even the smallest trace of feces of an infected dog may harbor the virus for a long time, the virus is readily transmitted through the feet, the hair, and even an infected cage of an infected dog.
The origin of parvo can be traced back to Europe in the year 1976, the virus continued to spread silently until it became a worldwide epidemic of myocarditis and intestinal inflammation by 1978. The virus is however not limited to dogs alone, asides from the fact that we mentioned that it could affect humans earlier, it can also cause infection in wild canines such as coyotes, wolves, foxes, raccoons, and skunks. However, our focus in this article would still be based on dogs.
When a dog gets infected with the virus, there is an incubation period of 3-7 days before the first symptom begins to display itself. Inside the dog, CPV would readily cause the disease, but it requires the help of a rapidly dividing cell in order to do that, the moment parvovirus gets into the body, it starts to attack the tonsils or the lymph nodes of the throat, inside the lymph nodes, the virus invades lymphocytes for two days, and makes lots of copies of itself. The virus then hitches a ride in the lymphocytes, where they get protected from the defense of the host and enter into the bloodstream. Most of the CPV-infected lymphocytes get killed at the end, therefore, creating a reduction in the number of circulating lymphocytes, when this happens, it creates another condition called lymphopenia.
Once this parvovirus gets into the bloodstream of the affected rapidly dividing cells, it hits the hardest bone marrow in the cells that lines up the wall of the mall intestine. In young dogs, the diseaseIi is able to affect the heart which would lead to the inflammation of the heart muscle, poor function, and arrhythmias.
Parvovirus in the bone marrow weakens the ability of the body to protect itself, which it does by engaging in the destruction of young immune cells and causing a decline in the protective white blood cell count. It is suspected that this makes it more ready for the virus to get into the gastrointestinal tract.
The signs of a dog with parvo are;
- A puppy that begins to show lethargy as a first sign.
- Loss of appetite.
- Serious diarrhea.
- When the disease attacks so much depth of the pet, the pet may experience hypothermia or collapse due to a high heart rate.
Major Infection Stages of Canine Parvovirus.
After randomly exploring what happens with parvo infection in pets, it is important to have these processes classified in the order of their occurrence;
Infection stage: The dog is exposed to viral particles in this stage, though; the mother dog, an infected environment even an infected human, Only a little amount of infected fecal material can affect the environment.
Incubation stage: This next stage of viral infection is the incubation period which would usually takes up to 3-7 days, in this stage, the infection has happened but the pet is not showing any physical symptoms yet. During this stage of infection, looks out for one of the dividing cells and then begins to multiply extensively. Once there is a case of multiplication, of it enters into the bloodstream, it would help to look for other hard-hit regions like the bone marrow and the cells that lines up the wall of the small intestine.
Illness Stage:: This stage of the infection happens when the virus infects the bone marrow, attacking the young immune cell, the pet's inability to protect itself allows the virus to evade the GI direct. The virus on getting to this stage begins to;
- Prevent fluid loss in the stool.
- Prevent bacteria from getting into the gut.
- Prevents the body from being able to absorb nutrients.
This illness stage breeds highly serious health issues like; fever, diarrhea, vomiting, lethargy, serious dehydration, and sepsis possibly.
The dogs that die from parvo infection usually die from shock or dehydration alongside the damage caused by the septic toxins from the point when the intestinal bacteria is escaping into the bloodstream.
Recovery phase: In order for a pet to recover completely from parvovirus, it may take quite some time depending on how severe the case is and how severe the damage that has been done is. Puppies with parvovirus need a lot of proper nutrition in order for their intestine to heal appropriately. They should also be fed a bland and easily digestible diet.
The treatment of parvovirus is mainly centered around providing support for dogs and increasing the ability of their body to be able to fight the virus. During the treatment phase;
- The dog would be hospitalized with intravenous fluids.
- Provided with antiemetics to seize the vomit.
- Focus on the provision of nutrition with a feeding tube (if needed).
- The correction of every form of electrolyte imbalance or low blood glucose.
Conclusion.
The best way to prevent the occurrence of parvovirus is to have your pet fully vaccinated and make sure that your pet only socializes with pets that are also fully vaccinated, if you are not sure about how vaccinated an environment is, avoid taking your dog to many places.
