The new strain of Coronavirus outbreak that was first identified in Wuhan, China, has put the world in high alert.

According to CNN’s latest reports, 231 people have died so far and over 9,709 cases were confirmed in mainland China. Adding to this, more than 60 million people are under partial/full lockdown in China in order to prevent further spreading of the infection.

Outside of China, the virus was identified in several countries including the US, France, Japan Australia, Canada, Thailand and now in India too.

Kerala has reported a case of the new Coronavirus in a student who had returned from Wuhan. The patient is now quarantined in Thrissur General Hospital.[1]

Coronavirus infection

Coronaviruses (CoV) are common viruses that cause infection in sinuses, upper throat and nose. Human Coronavirus is also responsible for the common cold.

Though most viruses are not dangerous, some types are serious like Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) which are rare.

While SARS (CoV) killed 774 people in the year 2003, MERS (CoV) killed around 858 people in the year 2012.

The WHO termed the Coronaviruses as ‘Zoonotic’, meaning, the Coronavirus infection was transmitted from animals to humans.[2]

Novel Coronavirus

On December 31st, 2019, Chinese authorities reported pneumonia-like disease among 44 people in Wuhan without any known cause to the World Health Organisation.  

A new virus was identified by the Chinese officials on January 7th, 2020. It was revealed that this new virus belongs to the Coronavirus family. Since this new strain was not previously identified among the humans, it was dubbed as the Novel Coronavirus (2019-nCoV).


This new strain of the virus is akin to the SARS and MERS – both are deadly and killed hundreds in the past. This Novel Coronavirus has also killed hundreds in just a month after the breakout. The virus is also challenging to contain. These factors make the Novel Coronavirus deadly and dangerous.

 It is worth mentioning that like SARS and MERS, the 2019-nCoV is Betacoronavirus. This means, the virus first appeared in bats. Some reports have also suggested that the virus may have originated from a wet market in Wuhan. However, this is only a speculation and no one knows how the virus passed to humans. [3]

Causes of Corona virus

The Corona virus infection is contagious and airborne and can easily spread from one human to another human.

The infection spreads through;

  • Air – sneezing and coughing.
  • Having personal contact with people who are having the infection like shaking their hands or touching them.
  • Touching your nose, mouth or eyes after touching an infected person or surfaces with the Coronavirus on it.
  • The infection rarely spreads through faeces.

The Coronavirus can infect anyone. However, children are more susceptible to it and therefore they should be taken better care to prevent them from catching the infection.[4]

Mild to moderate Coronavirus infection exhibits symptoms like the common cold.

The general symptoms are,

  • Headache
  • Fever
  • Sore throat
  • A general feeling of illness  
  • Cough and sneeze
  • Headache
  • Runny nose
  • Breathing difficulties

In severe cases, Coronavirus can cause SARS, MERS, bronchitis, kidney failure, pneumonia and even death. 

The symptoms of severe Coronavirus infection are;

  • Cough with mucus
  • Shortness of breath
  • In case of pneumonia, fever temperature can be high
  • Tightness in chest or chest pain when coughing or breathing

People who have lung and heart disease are more susceptible to developing severe infections.

Coronavirus Prevention

  • Avoid the consumption of undercooked/raw meat.
  • Handle meat, milk and animal products with care to prevent cross-contamination with other uncooked or undercooked foods.[5]

Coronavirus Treatment

There are no standard treatments for Coronavirus infection as mentioned above and treating the symptoms will help recover. People who have developed common Coronavirus infection will recuperate by themselves usually.

To relieve the symptoms, you can follow the below suggestions:

  • Take fever or pain medications.
  • Hot showers or drink hot water/soups to relieve cough sore throat.
