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.

 Causes Symptoms and Treatment of Herpes Simplex Infection

Meaning of Herpes Virus: Herpes, the first refers to the yellow-white or translucent small blisters that appear on the skin surface, often appearing as a sheet, which is full of liquid. Smallpox, chickenpox, etc. all have this symptom; the second refers to a skin disease. The pathogen is a virus, which mostly occurs on the upper lip or face. Itching first occurs locally, and then a blister-like bulge appears. It contains a transparent liquid. Slight pain, scab self-healing after a week or two. Herpes is divided into genital herpes, herpes simplex, and shingles. Today we come to understand one of them-herpes simplex.

What is herpes simplex?

In fact, herpes is a common and infectious skin disease with an ancient history, and the relevant records have even been seen in ancient Greece. Herpes simplex is an acute herpes skin disease caused by the herpes simplex virus. It can occur throughout the body. Humans are the only natural host for herpes simplex virus. The virus enters the body through the respiratory tract, oral cavity, genital mucosa, and damaged skin, and resides in the human normal mucosa, blood, saliva, and sensory ganglion cells.

The pathogen of herpes simplex is human herpes simplex virus, which belongs to the herpes simplex virus family α subfamily and herpes simplex virus genus. It is divided into two subtypes HSV-1 and HSV-2. HSV-1 subtype mainly invades the waist. The above parts, especially the face and brain tissue; and HSV-2 type mainly invades the lower waist, especially the genitals, etc., so it is called genital herpes; but this distinction is not strict.

Human herpes simplex virus does not have strong resistance to the outside world. It can be inactivated by heating at 56 ° C for 30min, UV irradiation for 5min, and other lipid solvents such as ether; however, its biological activity can be stored for a long time at -70 ° C.

 In vitro Culture

In an in vitro culture environment, herpes simplex virus can infect almost all kinds of embryonic and newborn animal-derived fibroblasts and epithelial cells, and quickly produce lesions visible to the naked eye. Therefore, in some difficult cases, the method of in vitro culture to isolate the virus can be used to help clinical diagnosis.

What are the Herpes simplex symptoms?

Everyone is not very familiar with herpes simplex. The previous article mentioned that herpes simplex can occur throughout the body. So what are the symptoms of herpes simplex?

Herpes simplex symptoms

1. Symptoms of primary infection herpes simplex

 The primary infection can be subclinical. If the clinical symptoms are present, the severity is greater than recurrent lesions. The incubation period is 3 to 5 days.

Herpes gingivostomatitis is the most common primary infection and occurs in children as young as 15 years. Gingival swelling and bleeding, blisters, erosions, ulcers on the tongue, pharynx, palate, and buccal mucosa. The ulcer is covered with a pale yellow false film with fever, discomfort, salivation, restlessness, bad breath, and painful eating. Local lymph nodes are enlarged and painful. . Fever subsides after 3-5 days, and usually fully recovers within 2 weeks.

2. Genital herpes:

Males are more common in the glans, foreskin and penis, and females are in the vulva, vagina, and cervical mucosa. Several red pimples and blisters occurred early, accompanied by local itching and burning sensations. Superficial ulcers formed after the blister broke, and dry crusts later. May have fever, discomfort, headache, fatigue and other symptoms. Without treatment, the course of disease lasts 2 to 3 weeks.

3. Inoculated herpes simplex:

The virus is directly inoculated on normal skin or skin abrasions. After 5 to 7 days, local hard papules, bullae, or irregularly dispersed blisters will appear. Local lymph nodes will swell and systemic symptoms are generally mild. Fingertip vaccination causes herpetic gangrene, local redness and pain, and the blisters fuse into a honeycomb appearance or form bullae.

Recurrent infection herpes simplex

Compared with the primary infection, recurrent blisters are smaller and denser, generally lack systemic symptoms, and often do not involve the buccal mucosa. There was a local itching or burning sensation 1-2 hours before the rash, and then clustered blisters appeared on the inflammatory substrate, which usually healed within 7 to 10 days without leaving scars.

The face is most often affected (especially around the mouth) and can occur in other areas. Relapses are usually in the same area, but not always in the same area. Genital herpes recurrence is extremely common and manifests as clusters of small blisters and superficial ulcers.

How does herpes simplex cause?

After understanding the symptoms of herpes simplex, friends of patients must find the symptoms of herpes simplex as soon as possible and put them into treatment as soon as possible. But many people are puzzled, how does herpes simplex cause it?

DNA virus herpes simplex virus infection (40%):

The disease is caused by the herpes simplex virus of DNA virus. Human herpes simplex virus is divided into two types, namely herpes simplex virus type I (HSV-I) and herpes simplex virus type II (HSV-II).

Type I mainly causes genitals. Infections of skin, mucous membranes (oral mucosa) and organs (brain) other than type II mainly cause skin and mucous membrane infections in the genital area.

Herpes Transmission (20%):

The virus enters the body through the respiratory tract, oral cavity, genital mucosa and damaged skin, and resides in the normal mucosa, blood, saliva and sensory ganglion cells of the human body. When the body's resistance decreases, such as fever, gastrointestinal disorders, menstruation, pregnancy, lesions When infection and mood change, latent HSV is activated in the body. Human is the only natural host of herpes simplex virus.

This virus exists in the blister fluid, saliva and feces of patients, restorers or healthy carriers. The main transmission method is direct contact infection. It can also be transmitted through tableware contaminated by saliva. Indirect infection.

Source of infection (20%):

It is clinically divided into primary herpes simplex infection and recurrent herpes simplex virus infection. Primary herpes simplex infections are caused by contact with patients with herpes simplex.

Herpes simplex virus can be transmitted through the mouth-breathing, or through the skin and mucous membranes. Infections at the herpes lesions, such as the cornea, and herpes simplex virus infection in infected patients and asymptomatic detoxifiers.

The virus is present in their saliva and feces. Therefore, patients with this disease should avoid contact with other children and young infants. Recurrent herpes simplex The infection is caused by the activation of latent herpes simplex virus in the body, and there is currently no ideal method to prevent recurrence.

How to treat simple cell rash?

How to treat simple cell rash? At present, the most effective treatment method of traditional Chinese medicine inhibition therapy: genital herpes is a stubborn disease, and it is difficult to cure it. Traditional medicine has been helpless for genital herpes. Topical Hericon drugs are rich in highly active proteolytic enzymes, which can quickly dissolve the protein shell of the herpes virus, allowing the drug components to quickly enter the virus and destroy the gene chain.

In addition, antiviral treatment is also the main treatment for herpes simplex

1. Acyclovir (ACV) is an open-chain purine nucleoside, which can inhibit the synthesis of viral DNA and has less effect on the synthesis of host cell DNA. It is considered to be the most effective anti-HSV drug at present.

 In severe cases, it can be administered intravenously at a dose of 5 mg per kilogram of body weight every 8 hours for a total of 5 to 7 days.

Ordinary patients can take orally, 200 mg each time, 5 times a day, or 800 mg each time, 2 times a day for a total of 5 to 7 days. It can reduce the virus quickly, reduce the symptoms and shorten the healing time. External use of 3% to 5% ACV ointment can also reduce symptoms and shorten the course of the disease. The drug has no significant side effects.

2. Hericang can obviously inhibit the replication of herpes virus and has a better effect on primary herpes.

3. Herikang can significantly inhibit the replication of herpes virus, and has a better effect on primary herpes.

What medicines are used for treatment?

Vaccines and immunosuppressants For patients with severe primary genital herpes and recurrent episodes, non-specific vaccines such as BCG and polio vaccines can be tried to improve the body's non-specific immunity, but their effects are less reliable and have immunosuppression And immunodeficiency patients.

Immune enhancers can be used in patients with recurrent genital herpes to improve the body's immune regulation. Such as levamisole, 50mg each time, 3 times a day, after taking 3 consecutive days, the drug is discontinued for 11 days, that is, 3 days every 2 weeks. You can also use levamisole coating solution, apply to the flexion of the forearm, once a day for 3 consecutive days. Take the medicine 3 days a week.

Chinese medicine external treatment method: Chinese medicine cream Hericang local symptoms can be eliminated within 30 days, increase exercise can not be lazy.

Can simple rash be cured?

I've been impressed to have seen a simple eczema on the face, and I hope this disease can be avoided. Can simple rash be cured? Doctors suggest to go to the hospital for treatment in time without too much mental load. Herpes simplex can be cured.

Herpes simplex is commonly called "fever herpes", which is a herpes skin disease caused by a virus. It often occurs in the course of fever and other fever diseases. Men, women, and children can occur in all seasons. A simple rash develops in a round-like development, with red rice dumplings with large rice or high grain size, pain and ulceration, and blisters.

Treatment is mainly symptomatic and to avoid secondary infections. Topical application is 2% gentian violet solution, 0.5% neomycin ointment, etc. Only when you pay attention to exercise, improve your immunity, and stop the outbreak of herpes virus is the only way to cure herpes simplex.

Is herpes simplex transmitted?

To understand herpes simplex, it is natural to know whether it is contagious.

Is herpes simplex transmitted? What aspects of life should you pay attention to to prevent herpes simplex?

Herpes simplex is an acute herpes dermatosis caused by the herpes simplex virus. Humans are the only natural host for herpes simplex virus. The virus exists in the blister fluid, saliva and feces of patients, restorers, or healthy carriers.

The main method is direct contact infection, and it can also be transmitted indirectly through tableware contaminated with saliva.

There are three things to note about preventing herpes simplex:

1. Keep the skin clean and take a bath every day. In hot weather, you can wash 2-3 times a day. Dress appropriately and don't sweat too much.

2. to protect the skin from damage, clothes, and bedding should be soft. Cut your nails frequently to avoid scratching the cuticle.

3. Avoid contact with people with skin infections. Wash your hands frequently.
