What is the Difference Between Coronaviruses?


The main differences between Coronaviruses

The difference between coronavirus and new coronavirus lies in virus type, clinical characteristics, route of infection, and severity of disease caused as doctors in Delhi observe.


1. Different types of Viruses:

Coronaviruses are a large family of viruses that are named for the morphology of the virus, which looks similar to a crown under an electron microscope. 

Coronavirus has so far been found to infect only vertebrates and can cause human and animal respiratory, digestive, and nervous system diseases such as colds and more serious diseases such as the Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The new coronavirus is a new coronavirus strain that has never been found in humans before. In addition to the new coronaviruses found this time, there are six more known coronaviruses that infect humans. 

4 of them are more common in the population and have lower pathogenicity, generally causing only mild respiratory symptoms similar to the common cold. 

The other 2 are the SARS coronavirus and MERS coronavirus that we are familiar with.


2. Severity of the illness caused:

Clinically, most coronaviruses cause mild and self-healing diseases, but a few may have neurological complications.


The illness caused by the new coronavirus is more serious. A total of 41 cases of pneumonitis with new coronavirus infection were reported in Wuhan initially, 7 cases were cured, 6 cases were cured, 1 case has died, and the remaining patients are in stable condition. 

All patients received isolation treatment at designated medical institutions in Wuhan.

Difference between dog parvovirus and coronavirus

The difference between a dog parvovirus and a corona virus. Dogs are not mental, and pulled and vomited some time ago ...


Difference between dog parvovirus and corona virus:


Simple points are generally small stool blood, coronavirus stool is green or orange or paste,

Is coronavirus and parvovirus a disease?

Canine coronavirus disease: 

The incubation period of artificial infection is 24-48 hours, and the incubation period of natural cases is 1-3 days. The sick dog is addicted to sleepiness, weakness, and anorexia. It can be seen that vomiting that lasts for several days, and then diarrhea begins. Yellow-green or orange-red, stench, mixed with varying amounts of mucus, occasionally a small amount of blood can be seen in the stool.

Canine parvovirus disease: 2 types of enteritis and myocarditis can be seen

1. Characteristics of the onset: The source of infection is mainly sick dogs and asymptomatic dogs. Rehabilitation dogs can be poisoned and detoxified for a long time, becoming a potential source of infection for the disease. 

Sick dogs detoxify via feces, reaching a peak at 4-6 days after illness, and the virus content tends to decrease after 9-14 days, but the infectivity can last from 30 days to 8 months.

Rickets can cause excretion of feces, urine, vomitus and saliva from healthy dogs. 

Pregnant dogs can also be transmitted vertically to the fetus through the placenta. Except for dogs, animals such as wolves, foxes, and marten are susceptible to infection. 

Puppies are particularly susceptible, with an incidence rate of 91.67% to 100%; the incidence rates of suckling dogs under 4 weeks of age and adult dogs over 5 years of age are 2% and 16% respectively; Is common.

2, the main symptoms: the incubation period of this disease is mostly 7-14 days. Clinical manifestations are related to the age, immune status and other factors of the sick dog. The symptoms of elderly dogs are mostly recessive, and the body temperature is generally normal.

This disease can be divided into the following two clinical types:

⑴ hemorrhagic enteritis type: more common in adult dogs. This type is more common in old epidemic areas. Sick dogs show symptoms of intestinal inflammation, usually vomiting and diarrhea first, in addition to draining yellow or gray thin stools, and then turning into tomato juice-like bloody thin stools, emitting a bad smell. 

The temperature of sick puppies can rise to 40-41 degrees (adult dogs' body temperature does not increase significantly). 

Swollen lymph nodes, small blisters in the mouth, and ulcers after rupture. Because the sick dog vomited and diarrhea, resulting in rapid dehydration, at the same time showing depression, anorexia, prostration, and finally death due to heart failure and acidosis. 

In addition to the decrease in serum total protein, the most significant hematological examination is that the number of white blood cells has decreased sharply within 4-5 days after the illness, at 300 / cm3 or 500-1000 / cm3.

⑵Myocarditis type: This type is common in newly infected areas. More common in puppies aged 3-4 weeks. 

The condition developed rapidly. A few sick dogs develop mild diarrhea and vomiting, usually with sudden weakness, dyspnea, and arrhythmia, and die within minutes.

The duration of the disease varies, with the short one taking a few minutes and the elderly taking several weeks. Mostly 5-7 days.

It is worth pointing out that clinically, all puppies with arrhythmia should consider the possibility of developing this disease. 

Due to the severe diarrhea and strong peristalsis of the intestine, subsequent cases of intussusception and prolapse of the anus have occurred.

The incidence of this disease is 20-100%, and the mortality rate is 10% -100%, especially in puppies (9-12 weeks old) who have just been weaned.

What is the relationship between Coronavirus and SARS?

SARS is a type of coronavirus. The Coronavirus family is divided into three genera: alpha, beta, and gamma. 

Beta gene coronaviruses include: beta coronavirus, human coronavirus HKU1, murine coronavirus, domestic bat coronavirus HPU5, Fruit bat coronavirus (HKU9), severe acute respiratory syndrome (SARS) -related virus and 7 species.


Clinical manifestations of SARS virus

The incubation period is 2-10 days. Onset is rapid, with fever as the first symptom. Body temperature is usually greater than 38 ° C, and there may be chills, cough, sputum sputum, occasional bloodshot sputum, palpitations, shortness of breath, or respiratory distress. May be accompanied by muscle soreness, headache, joint pain, fatigue, and diarrhea. 

Patients often had no catarrhal symptoms of the upper respiratory tract. Pulmonary signs were not obvious, and some patients could hear a slight wet murmur.


Extended information:


1. Transmission of SARS virus

It is excreted through respiratory secretions, transmitted through oral fluids, sneezing, and contact, and transmitted through air droplets. The peak of infection occurs in autumn, winter, and early spring. 

The virus is sensitive to heat. Ultraviolet rays, Lysol water, 0.1% peroxyacetic acid, and 1% keliaolin can kill the virus in a short time.


2. Prevention of SARS virus

Specific prevention of SARS virus prevention, that is, targeted preventive measures (the development of vaccines and vaccines is possible, but it takes a long time to solve the problem of virus reproduction is its problem) and non-specific preventive measures (that is, prevention of spring respiratory infections) Illness measures, such as keeping warm, washing hands, ventilating, avoiding excessive fatigue and contacting patients, and going to less public places, etc.).


Coronavirus is a single-stranded positive-sense RNA virus with a diameter of about 80 to 120 nm.

Its genetic material is the largest of all RNA viruses and only infects human, mouse, pig, cat, dog, and avian vertebrates. 

A variant of coronavirus is the pathogen that causes atypical pneumonia and belongs to the RNA virus.


I. Clinical manifestations

Symptoms are usually acute respiratory infections with acute renal failure.


Differences between viruses

There is a genetic difference between the new coronavirus and SARS virus, and it is not as easy to spread as SARS virus. There are far fewer cases of infection of new coronavirus than SARS, and the symptoms of some patients are different from SARS.



Extended information:


Way for spreading

Coronavirus is excreted through respiratory secretions, transmitted through oral fluid, sneeze, and contact, and transmitted through air droplets. The infection peaks in autumn, winter, and early spring. The virus is sensitive to heat. 

Ultraviolet rays, Lysol water, 0.1% peroxyacetic acid, and 1% keliaolin can kill the virus in a short time.


Preventive approach

There is specific prevention for its prevention, that is, targeted preventive measures (the development of vaccines and vaccines is possible, but it takes a long time to solve the problem of virus reproduction is its problem) and non-specific preventive measures (that is, prevention of spring respiratory infections) 

Measures such as keeping warm, washing hands, ventilating, avoiding excessive fatigue and contact with patients, and going to public places with fewer people, etc.).


What is coronavirus weak positive?

Patient information: Male 1-year-old Beijing Chaoyang District Condition description (onset time, main symptoms, etc.): My teddy bear, one and a half years old, vomiting, diarrhea, has been on a hunger strike for 4-5 days, and is mentally weak. 


Symptoms of vomiting and diarrhea, lack of appetite, and loss of energy. The weak positive reaction detected at this time is indicated by the middle and early stages of the onset of coronavirus. Coronavirus is a virus that attaches to the roots of intestinal villi. 

It continuously erodes the intestinal villi and eventually causes the intestinal villi to fall off. This causes disease. 

The clinical manifestations are diarrhea and vomiting. 

The difference between them and the small ones is that the small viruses attack the intestines The villi's head is different from canine fever in nature. 

Coronal and small are gastrointestinal diseases, which are used in humans to equal gastroenteritis. Canine fever is a comprehensive disease, including the respiratory system, digestive system and nervous system. The danger of these three diseases is canine plague> Small> Coronal. 

Generally, the coronal is better. Drip, water and food can be cured in 3-4 days. During the drip, it depends on the nutrient solution glucose and water in the drip to maintain it. 

Life, if it is a regular pet hospital, the ratio of drips completely meets the needs of dogs, so there is no need to be afraid of water and food breaks. 

Water and food breaks are to let the intestinal tract rest, so the intravenous method is used, and the antiviral serum is also injected at the same time. 

After treatment, the water intake was gradually restored, and the water intake gradually increased to the normal drinking water amount. If the water was not spit or pulled, you could resume eating, and the food intake gradually increased to normal. These three diseases can be life-threatening if not treated well, but if treated properly, the coronal can be cured in 3-4 days, and the small 7-10 days can be cured. 

Dog disease is difficult to say, mainly depending on the dog's constitution, and Sooner or later when the disease is found, canine plague has the highest mortality rate, close to 70%, and there will be various sequelae even if cured.

How is coronavirus transmitted?

For animals transmitted to humans, a medical academician of an Academy of Sciences, said that this time the coronavirus was transmitted to humans by humans and caused by humans eating game.
