A few months ago if someone had told you that schools, workplaces, transportation networks and even cities regions and countries all over the world would go into a lockdown that might have seemed quite incredible. 
What could possibly lead to such disruption of life across the entire world? Today, of course, everyone knows the answer to that question. It's the disease COVID-19, short for Coronavirus disease 2019.


Similar to how the disease called AIDS is caused by a virus called HIV. The COVID-19 disease is caused by a virus with the name Severe Acute Respiratory Syndrome Coronavirus 2 are simply SARS-Cov-2.

This virus is a member of a family all called coronaviruses. All of which attack the airways and lungs of animals. There are hundreds of such viruses, only a few of which infect humans.

Most Coronaviruses are confined to other animals, some occasionally mutate and make the leap from birds, bats or other organisms to humans. That is how a new disease suddenly emerges apparently out of the blue. The virus that only infected other animals is now able to infect our cells.

Why is this one getting so much attention?

The virus that first emerged in Wuhan China in December 2019 is a brand new coronavirus. so it's also referred to as a Novel coronavirus, one that didn't exist before.

Although it causes a respiratory illness similar to a flu virus. The coronavirus causing COVID-19 is not a flu virus. The two viruses are not in any way related genetically to each other and their modes of action are quite distinct. Since we've never encountered this coronavirus before, our immune systems haven't had the chance to learn how to deal with it.

What is coronavirus?


Coronaviruses are a large group of viruses. They consist of a core of genetic material surrounded by an envelope with protein spikes which gives the look of a crown. In Latin, the crown is called the corona.

There are various types of coronaviruses that cause Respiratory and gastrointestinal disorders. Respiratory disease can vary from the frequent cold to pneumonia. In most individuals, the symptoms are generally mild. However, a few kinds of coronaviruses could result in severe disease.

Severe acute respiratory syndrome coronavirus was initially identified in China in 2003. The Middle East respiratory syndrome coronavirus which was diagnosed in Saudi Arabia in 2012. The 2019 novel coronaviruses were initially identified in China.

It initially found in a group of people with pneumonia who'd visited the seafood and live animal market in Wuhan. The disease has spread from individuals who have been infected to other people such as healthcare staff and family members.

How Coronavirus get started?

The novel coronavirus outbreak was initially started in Wuhan, China in December. Now it has spread nearly every corner of the world. Millions of individuals around the globe have been infected and thousands of them have expired.

Health authorities in china affirm that heaps of people in Wuhan, China are being treated for pneumonia from an unknown virus. A lot of the infected had visited a live animal market in Wuhan. But authorities say there's not any evidence of this virus spreading from human to human.

January 11, 2020: Chinese state media reports the first death from novel coronavirus

Chinese state media reports the first death from novel coronavirus, a 61-year-old man who'd visited the animal market in Wuhan.

January 21, 2020: United state confirmed the first case of COVID-19

A man in his 30’s, who travelled to Wuhan, is diagnosed with the novel coronavirus. One day prior to the US, Japan, South Korea and Thailand had also reported their first cases.

How does this spread?

Most respiratory viruses are spread that come out by large droplets when people cough and sneeze. It stays aloft usually for about six feet in front of them.

They can land on surfaces, can also be transmitted between human to human by touching those surfaces, such as doorknobs or other surfaces. Other viruses can spread in the air and stay aloft for a longer period of time in small droplet nuclei.

We're not yet sure whether it is droplet or airborne transmission for this current 2019 coronavirus. So, we're just taking caution and protection as if it was spread by the airborne route.

Symptoms of coronavirus disease

The majority of COVID-19 cases are mild. Some even don't have any symptoms. If you are doing have symptoms, they might show up 2 to 14 days after exposure. They're presumed to be like a regular cold, the flu, or seasonal allergies, sort of a fever, headache, fatigue, inflammatory disease, and runny nose.

Coughing and shortness of breath are common, in step with the Centers for Disease Control and Prevention. The older you're, the more likely you're to experience severe sorts of these symptoms. Some cases have gastrointestinal symptoms, such as diarrhoea.

In more extreme cases and for people with other health conditions, like heart disease or diabetes, can develop pneumonia, frequent or high fever, persistent cough, and signs of respiratory distress, like shortness of breath and chest pain.

A small percentage of cases progress to acute respiratory distress, difficulty breathing and chest pain. Confusion, extreme fatigue, persistent pain or other severe symptoms require immediate medical attention.

Scientists across the globe are continuously working to try and find more details about the coronavirus. Every single day new details are being put into the general public domain. Now the United States Department Center for Disease Control and Prevention has gone ahead and updated the symptoms of the coronavirus six new symptoms. These symptoms are...

  • Chills

  • Repeated body shaking with chills

  • Muscle pain

  • Headache

  • Sore throat

  • Loss of sense of taste or smell

Diagnosis of coronavirus disease

The infection is often diagnosed by a test called PCR or polymerase chain reaction. In this test, the genetic fingerprint of the virus is obtained. Based on the genetic fingerprint, the virus is identified. Presently, there is no medication for the virus. The only treatment is supportive care. Currently, there is no vaccine which can protect against the virus. Treatment and vaccines are in development.

Steps to prevent the spread of the virus


  • Wash your hands frequently

  • Avoid touching your eyes, mouth and nose

  • Cover your cough with the bend of your elbow or tissue

  • Avoid crowded places

  • Stay at home if you feel unwell even with a slight fever and cough

  • If you have a fever, cough and difficulty breathing, seek medical care early

Myths about coronavirus

  • The virus will die off when temperatures rise in the spring.

Some viruses such as the cold and flu viruses do spread more easily in colder months. It does not mean that they stop entirely when conditions become warmer. As it now, scientists do not know how temperature changes will influence the behaviour of coronavirus.

  • Coronavirus is the deadliest virus ever.

COVID-19 is only fatal for a little percentage of the population. A recent report of the Chinese Center for Disease Control concluded that the maximum percentage of the infected cases were mild. The WHO also reported that around 80% of the people will experience a comparatively mild type of the disease which does not require any special treatment in hospital.

Although the coronavirus does appear to be more serious than influenza. It is not the deadliest virus that humanity has faced. Other viruses like Ebola have higher mortality rates.

  • Cats and dogs spread coronavirus.

At present, there's no evidence that animals or pets like dogs and cats are often infected with a brand new coronavirus. However, there has been a case report of a cat being tested positive for coronavirus after contracting it from his owner. But it is always a great idea to wash and sanitize your hands with soap and water after contact with pets.

  • Antibiotics and home remedies kill coronavirus.

Antibiotics can only kill bacteria. They are not effective against viruses at present. There is no home remedy that can treat or cure the novel coronavirus. The best defence against the infection is to adopt a good hand-washing regime and to avoid crowded places.

  • The virus was deliberately engineered in a lab.

Despite thousands of internet rumours, there is no credible evidence to support this claim. In fact, a recent study demonstrates that the virus may be a natural product of evolution. Some researchers believe that coronavirus originated in bats.

American medical research centre said that the coronavirus isn't a laboratory construct or a purposefully manipulated virus. We can firmly determine that coronavirus originated through natural processes.


We still are far away from a coronavirus vaccine. So follow the lockdown guidelines. Keep washing your hands after every 20 minutes and avoid crowded places. Boost your immunity because there is anything that can protect you from coronavirus is your own immunity.
