Coronavirus History


 

Where Did the Coronavirus Come From?

Experts say SARS-CoV-2 originated in bats. That’s also how the coronaviruses behind Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) got started.

SARS-CoV-2 made the jump to humans at one of Wuhan’s open-air “wet markets.” They’re where customers buy fresh meat and fish, including animals that are killed on the spot.

Some wet markets sell wild or banned species like cobras, wild boars, and raccoon dogs. Crowded conditions can let viruses from different animals swap genes. Sometimes the virus changes so much it can start to infect and spread among people.

Still, the Wuhan market didn’t sell bats at the time of the outbreak. That’s why early suspicion also fell on pangolins, also called scaly anteaters, which are sold illegally in some markets in China. Some coronaviruses that infect pangolins are similar to SARS-CoV-2.

As SARS-CoV-2 spread both inside and outside China, it infected people who have had no direct contact with animals. That meant the virus is transmitted from one human to another. It’s now spreading in the U.S. and around the globe, meaning that people are unwittingly catching and passing on the coronavirus. This growing worldwide transmission is what is now a pandemic.

Coronavirus Evolution

Scientists first identified a human coronavirus in 1965. It caused a common cold. Later that decade, researchers found a group of similar human and animal viruses and named them after their crown-like appearance.

Parvovirus in Puppies: Symptoms, Treatment, & Prevention

 Dog owners will go to great lengths to protect their beloved pooches from dangerous illnesses – after all, dogs aren’t just companions, but members of the family. Therefore, educating yourself as a pet parent is a responsibility not to be taken lightly.

Canine parvovirus (CPV) is an infectious viral disease that all pet parents need to be aware of, as it can lead to life-threatening illness. Certain dog breeds are more susceptible to this ailment, but all dogs should be vaccinated. This article will review the signs, symptoms, and treatment methods of this serious disease and how it can be prevented.

What Is Canine Parvovirus?

Canine parvovirus is a highly-contagious viral illness that can manifest itself in two different forms:

Intestinal CPV

The first and most common type of canine parvovirus is intestinal. Due to the aggressive nature of CPV, the virus attacks rapidly-dividing cells found in your dog’s body, most notably within the intestinal tract. Because the intestinal form of CPV inhibits your pet’s ability to absorb nutrients, he will become quickly dehydrated and weak from lack of fluid absorption and vital sustenance found in protein.

Parvo Symptoms in Puppies and Dogs Include:

Cardiac CPV

The less common strain is cardiac CPV, which attacks the white blood cells and damages the heart muscles. This form of CPV can be very dangerous to young animals, causing lifelong cardiac complications and even lead to fatality in some instances. Most reported cases affect puppies between six weeks and six months old; however, the occurrence of CPV infections has been greatly reduced by administering early vaccinations.

How Is Canine Parvo Spread?

Due to the acutely contagious nature of CPV, it may be transmitted easily by any human, animal or inanimate object that comes in contact with an infected dog’s fecal matter. Although there are a number of risk factors that can elevate a dog’s susceptibility to the disease, CPV is spread primarily via direct contact with another infected dog, or indirectly, by the fecal-oral route.

Because an infected dog’s feces contains heavy concentrations of the virus, it can be contracted very easily when a healthy dog sniffs the stool. Unvaccinated dogs frequently contract CPV from the streets during their daily walks, primarily in urban areas where the dog population is much higher.

Parvo in dogs and puppies is also highly-resistant, and therefore may live in your home environment for months at a time if not disinfected properly – it can survive on household objects such as your pet’s food bowls, carpeting, floors, and even clothing. One of the most common ways CPV is spread indirectly, in fact, is by way of shoes that have come into contact with infected dog feces.

Studies have indicated that the virus is capable of living in ground soil for up to a year, and is impervious to weather changes as well as common cleaning agents.

How To Clean A CPV-Contaminated Area

  • Wearing disposable latex gloves, pick up and safely dispose of all organic matter (feces, vomit etc.).
  • Next, wash the affected area thoroughly with a household bleach solution (diluted 1 part bleach to 32 parts water, or 4 oz. of bleach to a gallon of water).
  • Avoid using mops to clean, as it will only spread the virus around on hard surfaces and harbor germs within the mop itself. Instead, use rags or old towels and a scrub brush if necessary; dispose of safely after usage.
  • Launder all affected clothing, bedding, furniture, carpeting, towels etc. in hot water, using a high-quality detergent and bleach; it is also advised to use a clothes dryer vs. hanging up items to dry.
  • Be certain to wash hands thoroughly in hot water with antibacterial soap after any contact with a CPV-contaminated area. You may also wish to keep hand sanitizer on hand (use a product that is 70% alcohol); however, this should not be used in lieu of hand-washing, but as an added safety precaution.

Did You Know…

Research has shown that certain drug therapies and canine diseases that suppress the normal response of the immune system may also increase the chances of infection in some dogs; if you are uncertain as to the likelihood of your dog’s susceptibility, speak with your vet for more information.

The Dangers Of Not Vaccinating For Parvovirus

As discussed, parvo in dogs is easily transmitted; however, it can be prevented and controlled through adequate parvo vaccine protocols. There are numerous dog shelters and breeding kennels where unvaccinated puppies can become a health hazard to the canine population. Consequently, proceed with a degree of caution when adopting a new dog into your home. Be sure to research the breeder you’re adopting from to see if they are following appropriate practices with regard to cleanliness, medical treatment, vaccinations and so forth.

Did You Know…

There are certain dog breeds that are more prone to CPV, including Doberman Pinschers Pit BullsRottweilersStaffordshire Bull TerriersGerman ShepherdsLabrador Retrievers, Alaskan Sled Dogs, and English Springer Spaniels. Additionally, puppies, adolescent canines and dogs who aren’t vaccinated are most susceptible to parvovirus.

What Every Puppy Owner Needs to Know About Parvo in Puppies

 The last thing any new puppy owner or dog breeder wants to hear is a diagnosis of parvo. Parvo in puppies is unfortunately a common disease with deadly consequences, which is why it is important for anyone dealing with puppies on a regular basis to be aware of the symptoms of parvo and what to do about it.

What Is Parvo?

Parvo in puppies is caused by the canine parvovirus. This virus is highly contagious and spreads through direct contact with an infected dog or by indirect contact with a contaminated object. Your puppy is exposed to the parvovirus every time he sniffs, licks, or consumes infected feces. Indirect transmission occurs when a person who has recently been exposed to an infected dog touches your puppy, or when a puppy encounters a contaminated object, like a food or water bowl, collars and leashes, and the hands and clothing of people who handle infected dogs.

The Merck Veterinary Manual classifies the virus as a disease of the stomach and small intestines, as this is where the virus does the most damage. The virus prefers to infect the small intestine, where it destroys cells, impairs absorption, and disrupts the gut barrier. Parvo in puppies also affects the bone marrow and lymphopoietic tissues, and in some cases can also affect the heart.

Why Do Puppies Get Parvo?

Puppies ages six weeks to six months are the most susceptible to parvo. Puppies younger than six-weeks-old still retain some of their mother’s antibodies, assuming that the dam received her full series of parvo vaccinations. Puppies are vaccinated against parvo at approximately 6, 8, and 12 weeks of age. They are vulnerable to the disease until they have received all three shots in their vaccination series, which means owners need to take extra precaution during this time to prevent their puppies from contracting the virus. Puppies should receive a dose of canine parvovirus vaccine between 14 and 16 weeks of age, regardless of how many doses they received earlier, to develop adequate protection.

The severity of parvo cases varies. The stress of weaning can lead to a more severe case of parvo n puppies, as stress weakens the immune system. A combination of parvo and a secondary infection or a parasite can also lead to a more severe case of parvo in puppies.

To top it off, certain breeds of dogs are at an increased risk of parvo:
