People around the world are in a panic right now since the outbreaks of the novel coronavirus (2019-nCoV). There is a sense of fear and confusion as it was so sudden. Therefore, everyone must know a few important things about the coronavirus.

Things to know about coronavirus

So, below are the top 5 important things one must know about the coronavirus.

1. What is a coronavirus

The coronaviruses are a big family of viruses that causes illness among humans and animals. It creates a condition like a common cold or flu.

The first coronavirus was detected in the 1960s in chickens. Subsequently, two viruses were discovered from the nasal cavity of humans who were suffering from the common cold. Those viruses were named as Human coronavirus 229E and Human coronavirus OC43.

Nevertheless, that does not mean it was not present before 1960. Surprisingly, the closest relatives of this virus were traced back to as old as 10,000 years.

Over the years many other strains of coronavirus identified in humans and some of them caused global epidemics. Among them, most notable are Severe Acute Respiratory Syndrom (SARS-CoV) in 2003 in China and Middle East respiratory Syndrom (MERS-CoV) in 2012 in Saudi Arabia.

They are one of the largest RNA viruses and the name was given because of its crown-like appearance under electron microscopy.

2. You may have already got coronavirus infection

Everybody suffers from the common cold in their lifetime. You even didn’t visit a doctor for a mild illness. That coughing or sneezing might have happened for coronavirus infection. Most people get a coronavirus infection in their lifetime.

All human coronaviruses are not deadly as SARS, MERS or the novel coronavirus. Therefore, we don’t seek medical attention and the diagnosis remain in dark. Our immunity can easily wipe out those scams all most all the time.

3. The novel coronavirus is the 7th strains of the coronavirus that infect humans

There are 7 coronavirus strains that can infect humans. The novel coronavirus is the latest and 7th family member of the group.

It was first detected in early December in Wuhan city of Hubei province in China. On the 9th of January, the World Health Organization designated it as a new coronavirus and named it 2019-nCoV.

The number of new coronavirus infections already near to 10,000 and is rising rapidly. The situation is so intense, China has locked down a number of its major cities and many countries are banning their citizens to visit China.

As of 30th, January 2020, death due to corona infection passed 213 and many are still in critical condition. Moreover, the World Health Organization has declared the outbreaks of novel coronavirus as a global health emergency.

In fact, the terms novel itself means newly discovered or newly originated.

4. All Coronaviruses cause respiratory tract infection

Respiratory tract infection is the predominant feature of coronavirus infection. All virus strains affect the lungs and upper respiratory tracts such as throat and nose.

When our body recognizes that a virus is disturbing, it initiates an immune response. As a result, self-destruction of cells starts which releases a huge amount of water. Consequently, people who get the infection, develope fever, cough and breathing difficulty.

Later on, those, in turn, involve other organs and people who have weak immunity face critical conditions.

5. The transmission does not need physical contact

The virus transmits via close contacts and droplets during coughing and sneezing through the air. Even coughing or sneezing from a 3 to 6 feet distance can infect another person. Therefore, you don’t have to make any physical contact to get the infection.

Moreover, anyone can carry the virus without showing any symptoms. That makes it scarier. Because you don’t know who should avoid.

However, the source of the virus is still unknown. Furthermore, the asymptomatic ratio and healthy carriers are still in dark. As a result, it will be difficult to prevent the virus from spreading the disease.
