About COVID-19

Coronavirus symptoms and full information

Coronaviruses (COV) are a large family of viruses that cause common illnesses such as Middle East Respiratory Syndrome (MERS-CoV) and Acute Respiratory Syndrome (SARS-CoV).

A novel coronavirus (nCoV) is a new species not previously identified in humans.

Coronaviruses are zoonotic, meaning they spread between animals and people.

 A detailed investigation revealed that SARS-CoV was transmitted from quail cats to humans and MERS-CoV to humans from dromedary camels. Most known coronaviruses are circulating in animals that have not yet infected humans.

Common signs of infection are respiratory symptoms, fever, cough, shortness of breath and difficulty breathing. In more severe cases, the infection can lead to pneumonia, acute acute respiratory syndrome, renal failure and even death.

The standard recommendations to prevent infection are to wash hands regularly, cover the mouth and nose when coughing and sneezing, and to cook meat and eggs thoroughly.

 Avoid close contact with those who show signs of respiratory disease such as cough and sneezing. In humans, these viruses cause respiratory infections that range from mild to malignant. Mild illnesses include some cases of the common cold (which can also be caused by other viruses).

Mainly rhinoviruses), the most deadly types causing SARS, MERS and COVID-19. Symptoms are different in other breeds: in chickens, they cause upper respiratory disease, but in cows and pigs they cause diarrhea.

In the coronavirus family, Coronaviridae, order Nidovirles, and Ribom riboviria belong to the subfamily Orthochoronerina. They are viruses that are positively understood single-stranded RNA genes and nucleocapsids of helical symmetry.

The genetic size of the coronavirus ranges from 26 to 32 kg, making it the largest of the RNA viruses. They project club-shaped spikes from their surface, creating an image in electron micrographs, reminiscent of the solar corona.

The name "coronavirus" comes from the Latin corona, meaning "crown" or "wreath", derived from the Greek ώορώνη corona, "wand, wand".

The name was coined by June Almeida and David Tyrell, who first examined and studied the human coronavirus.

 The term was first coined in 1968 by a team of unofficial virologists in the journal Nature to recruit a new family of viruses. The name refers to the characterization of viruses (infectious forms of the virus) by electron microscopy, with a large, bulging surface margin reminiscent of the solar corona or halo.

Coronavirus symptoms and full information

This morphology is caused by viral spike papillomas, which are proteins on the surface of the virus.

Coronaviruses were first discovered in the 1930s when acute respiratory infections of domestic chickens were caused by the infectious bronchitis virus (IBV).

Arthur Schulk and M.C. In 1931, Han described a new respiratory infection of chickens in North Dakota.

Infection of newborn chickens is bloated and difficult to hear.

The mortality rate for girls is 40-90%. Fred Budett and Charles Hudson successfully isolated and cultivated the infectious bronchitis virus six years later, causing the disease.

In the 1940s, two other animal coronaviruses, the mouse hepatitis virus (MHV) and the infectious gastroenteritis virus (TGEV) were isolated. The nature of these three different viruses was not understood at the time.

The human coronavirus was discovered in the 1960s. They were separated using two different methods in the United Kingdom and the United States. E.C.

In 1960, Kendall, Malcolm Bain and David Tyrell, who worked in the British Medical Research Council's Common Cold Unit, split with the novel Common Cold Virus B814.

Rhinoviruses, adenoviruses and other known freezing cold viruses have not been successfully harvested using standard methods.

In 1965, Tyrell and Bayon cultivated the novel embryonic viruses by successfully traveling through the organ culture of the human embryonic trachea.

A new farming method was introduced at the Bertil Horn Laboratory. When the isolated virus is voluntarily incorporated into volunteers, it causes clotting and indicates that there is a lipid envelope by the ether.

At the same time, Dorothy Hamre and John Prior of the University of Chicago isolated the 229E novel cold virus from medical students and grew it in kidney tissue culture.

 The strain of the novel virus 229E is similar to strain B814, which when vaccinated by volunteers is clotted and inactivated by ether.

Communication of Organ Cultured Electron Micrographs Cultured OC43

Two novels, B814 and 229E, were later photographed by electron microscopy in 1967 by Scottish virologist June at Almeida St.

Thomas Hospital in London. Through electron microscopy, the Elimida B814 and 229E were able to show that their feature was morphologically related to club-like spikes. They are not only related to each other, they are also related to the infectious bronchitis virus (IBV). That same year a research team at the National Institutes of Health was able to isolate another member of this new group using organ culture and named the virus OC43 (OC for organ culture). Like the B814, 229E, and IBV, the Cold Virus OC43 novel has distinctive club-like spikes when viewed with an electron microscope.

Novel cold viruses such as IBV were soon shown to be related to the mouse hepatitis virus.

This new group of viruses, such as IBV, is called coronaviruses after their unique morphological form. Human coronavirus 229E and human coronavirus OC43 continued to be studied in the following decades.

Coronavirus virus B814 is gone. It is unknown at this time what he meant by human coronary. Human coronaviruses have been identified since then, including SARS-CoV in 2003, HCoV NL63 in 2004, HCoV HKU1 in 2005, MERS-CoV in 2012 and SARS-CoV-2 in 2019. A large number of animal coronaviruses have been identified since the 1960s.

Coronaviruses are large, broadly rounded, bulging surface cells. The average diameter of virus cells is 125 nm (.125 m).

The cover has spikes of 85 nm diameter and 20 nm length. In an electron micrograph, the envelope of the virus appears as a special pair of electron-dense spheres (shells that are relatively opaque to the electron beam used to scan the virus cell).

The viral envelope contains the lipid bilayer, which anchors the membrane (M), envelope (E) and spike (S) structural proteins.

The ratio of E: S: M in the lipid bilayer is 1: 20: 300. On average, a coronavirus cell has 74 surface spikes. Coronaviruses (especially members of betacoronavirus subgroup A) have a small spike-like surface protein called hemagglutinin estenes (HE).

Coronavirus virus spores are homeostasis of the S protein, which is composed of S1 and S2 subunits.

 The homotrimeric S protein is a class I fusion protein that mediates receptor binding and membrane fusion between the virus and the host cell.

The S1 subunit forms the core of the spike and contains the receptor binding domain (RBD). The S2 subunit forms the stem that anchors the spike in the viral envelope and allows fusion on protease activation.

E and M proteins are important in creating the viral envelope and maintaining its structural structure.

Inside the envelope is the nucleocapsid, which contains multiple copies of the nucleocapsid (N) protein that binds to the positive-sense single-stranded RNA gene in a continuous bead-at-a-string type deformity.

Lipids protect the bilayer envelope, membrane proteins, and nucleocapsid viruses when they are outside the host cell.

You need to be careful if you do not get the taste of the ingredients in the food and you can smell the objects around you. The corona should be tested. The Union Ministry of Health on Saturday introduced a reduction in the ability to smell and taste the symptoms of the corona virus.

The debate on this topic has been going on for a long time. The decision was taken by the National Task Force after extensive discussions. Corona sufferers have been found to have lower taste and odor abilities, so they are now included in the symptoms of infection.

The number of people infected with the corona virus (COVID-19) is over 1.17 crore. It killed 1.32 million people in the US. There are three million people infected with the virus. Even in India, the number of corona victims has exceeded

Corona virus symptoms and preventive measures

'' main symptom of corona virus is high fever that we cannot thought''. It is only of concern in children and adults when it reaches 100 F (37.7 ° C) or higher.

According to the World Health Organization (WHO), 88 percent are infected with the flu, 68 percent with cough, 38 percent with fatigue, 38 percent with shortness of breath, 18 percent with body aches, headaches, and 11 percent with corona virus infection. It contains 4% of signs of irritation and diarrhea. That means runny nose.

 Nasal congestion is not considered a corona virus signal. Most cases are found where corona symptoms do not appear. Therefore you need to take extra precautions.

Let us know what are the symptoms and ways to prevent this virus.

What is a coronavirus?

Corona virus belongs to the family of viruses that can cause infections ranging from colds to shortness of breath. virus has came first time to seen.

The virus started in December in Wuhan, China. According to the WHO, flu, cough, shortness of breath are its symptoms. To date, no vaccine has been developed to prevent the spread of the virus.

What are the symptoms of this disease?

Its symptoms are similar to the flu. As a result of the infection, complications such as fever, chills, shortness of breath, runny nose and sore throat can occur.

virus transmits form one to another by casual contacting. So, pay close attention to this. In some cases, the corona virus can be fatal. Especially the elderly and those already suffering from asthma, diabetes and heart disease.

What are the preventive measures?

The Department of Health has issued guidelines for the prevention of corona virus. According to him, hands should be washed with soap.

 Hand based rubbers can also be used. Cover your nose and mouth with a stick or tissue paper in the form of a cough and sneeze. Those with flu and flu symptoms, stay away from them.

 Avoid eating eggs and meat. Protect contact with wildlife.

Consider these signs to identify the corona

High fever: If a person with a dry cough has a high fever, they should be tested once. If your temperature is 99.0 and 99.5 degrees Fahrenheit, it is not considered cold. It is only concerned when the temperature reaches 100 F (37.7 ° C) or higher.

Sputum and dry cough: The corona virus has been found to cause phlegm, but the infected person coughs.

Respiratory problems: Within 5 days of being infected with the corona virus, a person may have difficulty breathing. Respiratory problems are actually caused by the spread of sputum in the lungs.

Flu Symptoms: According to the World Health Organization (WHO), corona virus infection can sometimes cause fever and cough as well as flu and cold symptoms.

Diarrhea and vomiting: Diarrhea and vomiting are also seen in people with corona. Such features are virtually visible

Corona virus deaths

1. Children up to 9 years - 0 percent

2.0.2% of 10–39 year olds

3.0.4 per cent in the age group of 40-49 years

4.1.3 percent of those aged 50-59

5.3.6 percent of those aged 60-69

6.3.6 per cent of those aged 60-69

7.8 per cent in the age group of 70-79 years

8.14.8 per cent of those over 80 years of age

WHO's 9.7 Steps to Corona Virus Prevention

10. The World Health Organization (WHO) states seven easy
 Steps to help prevent the spread of corona virus and prevent infection by itself.

The Government of India also advised

The Government of India has requested that the health center be informed immediately if there are any symptoms of corona virus. The Ministry of Health has set up a 24-hour control room.

The control room can be contacted at 011-23978046.

Thirteen different symptoms of coronavirus have been reported worldwide. The WHO announced these new features on its website. These symptoms have been seen in patients who have taken Kovid-19 worldwide in the last two-three months.

General features of the corona

The corona virus attacks your lungs directly. This makes one of the two features appear.

Fever or dry cough. If anything like this happens, it will be difficult to breathe.

However, this does not stop the cough. You can cough for hours, or you can cough three or four times a day.

It is more severe than your normal cough, so be careful. During this time the throat also becomes red and painful. Therefore, samples taken from the throat swab are tested for Kovid-19.

When you have a fever, your body temperature can be above 37.8 than C. It makes you feel a little awkward, cold or shivering.

Symptoms sometimes last up to five days and sometimes longer. According to the WHO, the virus can take up to 14 days to show its effects on your body.

This is called the incubation period.
According to the latest information provided by the US Center for Disease Control, you should be alert if you notice any of the following symptoms.

1. Fever or cold


3. Pain in the muscles


5. Cough or sore throat

6. Taste or smell


8. Clearly, the list of symptoms is only fever, cough or difficulty in breathing.

Speaking at a press conference on May 24, Chief Minister Uddhav Thackeray said fatigue and bad breath were also symptoms.

The United Kingdom government has also stated that these are new features. There are symptoms such as persistent cough, bad breath and bad breath.

What are the new features of the corona?

The WHO lists 13 features of the corona virus on its website. The most common of these symptoms is described earlier. However, some patients around the world have symptoms that are now visible.


10. Blood stains, skin rashes

11. On the toes and palms


13. Nani nose

14. Diarrhea or diarrhea

15. Body pain

16. Anytime symptoms

17. Rapid pain

18. Chest pressure


Stop the movement of the body

What is the risk of death?

The number of people who die from this disease is 1 to 2 percent lower. But these figures are not entirely reliable.

In some places there is no adequate system for diagnosis and in other places symptoms do not appear and patients are not recognized.

According to a World Health Organization study, approximately 65,000 patients -

6% of patients have a toxic condition - which means they are at risk for lung and lung failure, other infections, organ failure and death.
14% of patients have severe symptoms - difficulty breathing, etc.
Eighty percent of patients have mild symptoms - fever, cough or pneumonia.

Statistics show that people with diseases such as asthma, diabetes, high blood pressure and heart disease are more likely to get the disease. Statistics indicate that men are more at risk of death than women.

Do you have a medicine in Corona?

Dexamethasone is very useful in the deadly fight against the corona virus, say UK experts. Dexamethasone is an inexpensive medicine drug and can be found everywhere.

This drug may be important in saving the lives of people suffering from a serious illness such as corona. Dexamethasone is one of the drugs being tested to control the corona virus. These tests test the efficacy of dexamethasone.

At the same time, the World Health Organization also hopes. Regarding drug use, World Health Organization Director-General Tredos Gabraces said it was a steroid. The use of this medicine has shown good results in patients with complex illness.

You will find detailed information about dexamethasone in the following articles.

Dexamethasone has side effects, stop if you take it directly
What should I do next?

Recent studies have suggested that the corona virus may be transmitted through coughing or shortness of breath, or by touching the nose and mouth when hand drops touch the fallen area.

Also, experts often say that there is a risk of such infections in densely populated areas.

do it regularly to prevent yourself from the infection--

Don’t get too close to being sick.

Do not touch mouth, nose, eyes, ears without washing hands.

Use tissue paper when sneezing and coughing. After use, throw it in the trash and wash your hands.

Wash your hands often with soap.

The WHO has not yet asked whether the use of the mask could actually inhibit the corona. But use it if you go to a densely populated area.

If you are asked to isolate people or stay indoors, do exactly that. To achieve this you need to know what to divide or divide.

Care should also be taken to prevent coronary heart disease in children. You will find full details on these two topics in later articles.

When should people go to the hospital?

Most people infected with the corona virus can get relief by taking paracetamol and the flu pill. However, if you have difficulty breathing, you should go to the hospital immediately.

 The doctor then takes an X-ray of the patient's chest to see how much sputum has accumulated in the chest. It is decided whether to deliver oxygen to the patient or to place it directly on the ventilator.

If you have trouble breathing, call Kovid-19's National Adline Number immediately. The number of this national helpline is + 91-11-23978046 (call 011 from cell phone).

Also, the pathology report showed that the corona was blocked. So the details of what to do next are given in the following stories.

What do you do if you have symptoms of corona virus?

What exactly happens in the ICU?

Very sick
These patients are treated in the ICU. Patients with corona receive oxygen through an oxygen mask. If this does not happen to the patient, a nasal tube is inserted.

If the patient's condition worsens, he is placed on a ventilator in the ICU. The tube is inserted directly into the body through the nose or mouth.

 Large amounts of oxygen are transported directly to the lungs through this tube.
