According to the World Health Organization, On December 31, 2019. They received information about the cases of pneumonia in China. Which were due to some unknown reason in Wuhan. Later, it proved as new Novel Coronavirus. It’s been 3 months now and scientists haven’t fully understood the novel coronavirus yet. But what they have learned so far is that the virus is not as scary as it is. It is not the worst and world-destroying virus.
The disease COVID-19 is not as contagious as measles and it is certainly dangerous. But, it cannot kill an infected person like Ebola. But one thing that is very important in regards to the destructive potential of this SARAS COV 2 virus is its newness or novelty.
In Wuhan China, the mysterious pneumonia-like cases of respiratory disease were reported at the end of December. But, after some days it start spreading rapidly. In fact in less than 3 months, the virus has infected 1,447,466 people 83,471 has died. With lockdowns in most countries around the world, routine life has stalled, the global economy has not been able to handle the shock and it seems that the nerves of billions of people imprisoned in homes are close to breaking down.
Why is this virus so dangerous?
Coronaviruses are not new to the world, but they often cause respiratory diseases that range from seasonal influenza to life-threatening illnesses like epilepsy such as SARS and MERS. But SARS Cov 2 is the first Coronavirus to be called a global pandemic and the cause is not surprising. Because it was a new virus that appeared in humans and we became helpless in front of it.
Most infectious diseases that are present in the world suffer to some degree because people have some degree of immune to them, but the coronavirus is driving away every obstacle that comes it’s way. The greatest danger is that when the virus makes people sick, the disease does not appear immediately.
According to various research reports, the duration of the outbreak of coronavirus on average is 5 days. But before it can be infected other healthy people can be infected. This means that the virus is specialized in stealth transmission and as a result it is spreading rapidly.
Comparison to other Viruses
Only a few days after the outbreak of this virus. Scientists in China created the DNA structure of the sequence of this virus. According to it, this virus isn’t different from the SARS 2002 coronavirus. That’s why it has been named as SARS COV 2.
One out of every 10 patients was died by the SARAS Virus. But its victims did not transmit the virus until they became ill and by the time most of the patients had reached the hospital.
The virus was soon controlled, so much research has not been taken into account by scientists in recent years. And now it has returned to its new form in a more contagious and powerful manner. While safe and effective vaccines are being worked out to prevent it. But the possibility of availability does not seem possible until a year ago.
How does it spread?
The volume of this new coronavirus is less than a thousandth of a second in our eyelid and is essentially a thorny protein shell that is dead or zombie-like outside of the human body. But once it enters in human drain, it captures our cells and produces millions of viruses like itself.
In fact, the way the coronavirus works is what bothers the mind, it enters the human body, and by the time the symptoms appear in an infected person, it has spread its copy everywhere in the body and into another target (Human beings). That is, a patient transmits it to a healthy person, in which small particles emitted from the mouth during coughing or sneezing play a role.
How does the virus work?
Once infected with human body cells, a virus can produce 10,000 copies in a few hours, and within a few days millions of viral particles may be present in each particle of the affected person’s blood. As a result of this attack, the body’s immune system releases defensive chemicals in response to stress, which raises the body’s temperature, ie fever while the white blood cells of the germs invade the affected area, which As a result, people begin to feel ill.
You may not know, the virus do not have their own cellular machinery like bacteria. So they become part of our body. Their proteins are our proteins, their weakness is our weakness. Those drugs which can hurt virus, they can also harm us. This is why antiviral drugs are designed for specific targets and target the proteins that make up the virus using our cell machinery.
Viruses go through very rapid evolutionary stages and this is why their treatments are often not effective for very long periods of time. But often require the development of new drugs, such as those used to treat HIV infection.
But the good news about this new Coronavirus is that its evolutionary speed is much slower than other viruses like the flu virus. The virus is stable in its current state and will not be even more dangerous when it spreads, and the other thing is that the vaccine produced will prove to be effective on a long-term basis.
What are the effects inside the body?
In serious cases, the virus can have devastating effects on the body and not just the lungs. Like other coronaviruses, including SARS, MERS, and common seasonal colds, COVID-19 is a respiratory disease, so the lungs are usually the first to be infected. Early symptoms, such as fever, cough and difficulty breathing, appear within 2 to 14 days after the virus is infected.
In mid-March, medical experts in Hawking Kong discovered that the lungs of those treated with the new Novel Coronavirus could suffer from lung weakness and that some people might have a problem with breathing problems.
According to a report by the South China Morning Post, the Hong Kong hospital authority concluded this after reviewing the first patients recovered from the coronavirus disease COVID-19. Doctors discovered that 2 to 3 out of 12 patients had changes in lung capacity.
Arteries of the heart and blood:
According to Dr. Laura E Evans of the University of Washington Medical Center, the virus can also potentially affect the heart and blood vessels, which can cause irregular heartbeats, impair blood supply to tissues, or lower blood pressure. Yes, but it is not yet known whether the virus directly damages the heart.
Why does it get worse in some people?
In 80% of patients, the severity of COVID-19 is moderate or very low, but in 20% the severity of the symptoms may be very high or severe.
But why does this happen?
Apparently this is because of the immune system whose vulnerability or weakness may affect the severity of the disease. While there may be some genetic factors. But at present it is difficult to say for certain. But scientists hope that understanding this process will help people to find ways to prevent its severity from escalating.
Research published in the journal Nature Medicine in March discovered that four immune cells within the body are active against this new novel coronavirus. Researchers discovered that the patient’s body is invading the virus in the same way that it is against the flu.
The study involved a 47-year-old woman from Wuhan, China, who confirmed the mild symptoms of COVID-19. The woman was taken from Wuhan to Australia. She was diagnosed with the disease 11 days at a hospital in Melbourne. Although she apparently had not been contacted by a previously affected person.
After taking the patient’s blood samples before and after treatment. The research team discovered that her body had been attacked in different ways against the virus. Although the body had never encountered the virus before.
According to the World Health Organization, the most common symptoms of Code 19 include fever, fatigue and dry cough, some patients may also experience discomfort, itching, runny nose, runny nose, throat swelling or diarrhea.
How to protect yourself?
It is very easy to avoid this virus. In fact the precautions that can be taken to prevent colds or the flu. They can also be helpful to prevent by this new coronavirus.
1: The most basic thing is good hand hygiene for which first soak your hands with clean water and then apply soap, soap foam on the palm and back of the hands, between the toes and the upper surface of the nails. Rub for at least 20 seconds and then wash.
2: Flu, colds and cough are very common diseases and some of the common symptoms of coronavirus include, during sneezing or coughing, small particles from the mouth are emitted which can transmit the virus to the other persons. So the best way is to cover your mouth and nose with your hands or elbows for coughing or sneezing, and then wash them. If using a tissue, throw it away immediately.
3: If a person appears to be coughing or sneezing, stay at least one meter away, because when someone coughs or sneezes, they emit small fluid particles from the mouth that can be infected with the virus, if you are very close. So, by inhaling these particles, the virus can enter the body.

4: For healthy people the use of coronavirus protection masks is becoming more prevalent. Which can provide some protection in blocking out small particles from the mouth of an ill person. But does not block the small particles in the air. Which can pass through the mask’s material. The mask also does not protect the eyes and there is evidence that some viruses can infect a person through the eyes. However if you are experiencing coughs, nausea, etc., use a face mask to protect the people around you and yourself.

5: Do every possible thing to avoid touching the eyes, nose and mouth, if compulsory, work it through the tissue or throw it away.
6: Clean the most frequently used items and their surfaces daily so that they do not contain the virus. As it is believed that coronavirus can remain in the environment for up to 9 days in certain environments.
7: If you are ill and for some reason believe that it may be a coronavirus, call for medical help as soon as possible and instead of going to the hospital yourself, seek medical help at home. So, you can protect others from this virus. That can transmit to others during your journey to the hospital.
8: Social distance, such as confining yourself to homes, protects you from this virus and protects others.
Cases and deaths:
By April 7th, due to coronavirus 1,450,343 cases reported worldwide. The death toll due to coronavirus has risen to 83471. The number of recovered patients is 308,617. Surprising is that 1 lac cases were completed on 7th March and the remaining 13 lac cases reported just in 20 days.
The epidemic also affected many prominent figures. Star Wars star Andrew Jake, American chef Floyd Cardoso, American writer Terrence McNeill, Congo music legend Oluis Mablei, African saxophone legend Manduibangu, American singer Alan Merrill, American actress Lee Ferro died of the illness.
Hollywood actor Tom Hanks and his wife Rita Wilson, Prince William of British prince Charles, Prince Albert of Monaco, Brazilian Minister of Energy Bantu Albaccio, Brazilian National Security Advisor Augusto Helino, British Prime Minister Boris Johnson, several politicians from Iran. Several celebrities, including Punk, French actress Olga Kvurlenko, actor Idris Alba, actor Christopher Huejo, and Mayor of Miami Francis Sorrez are battling the pandemic.
First, China imposed travel bans at the country level, including Wuhan, and then in other countries. Japan first ban the arrival of people from certain parts of China and South Korea. Which were later extended to 21 European countries and Iran. While those arriving from the United States were ordered to quarantine for 14 days.
Australia and New Zealand ban the arrival of all foreigners. While Australian nationals from overseas were forced to spend two weeks in Quarantine. This is happening in Singapore too, and with the ban on foreigners, all citizens have been instructed to stay at home for 14 days. Everyone coming from overseas in South Korea is undergoing a 2-week mandatory quarantine process.
In Canada, the US and European countries, sanctions are also being imposed. While visas for all foreigners have been suspended in India until mid-April.
Partial of complete lockdown is imposed in the countries including, Pakistan, India, Australia, Argentina, Belgium, China, Colombia, Czech Republic, Denmark El Salvador, France, Germany, Israel, Italy, Jordan, Kenya, Kuwait, Malaysia, Morocco, New Zealand, Norway, Poland, Ireland, Russia, Saudi Arabia, South Africa, Spain, the United Kingdom and Hungary.
Lockdown is now gradually eradicated in China. Extreme lockdown the measure have been taken in India, France, Italy, New Zealand, Poland and the United Kingdom. More than 2.5 billion people around the world are facing the restrictions of lockdown.
Currently there is no cure or vaccine for this global outbreak, but the symptoms are treated and more than 80% of patients are cured. However, scientific efforts are being made to cure it worldwide.
