What is Coronavirus?

Coronavirus is a family of various viruses clubbed together and surrounded by protein spikes, giving it the appearance of a crown. This gives us the reason why this virus is termed as ‘Corona’ – that looks like a crown. The new coronavirus, widely known as COVID-19 or SARS-COV2, was first detected in Wuhan, China, in December 2019. From a mysterious illness to a global pandemic, deadly COVID-19 is now creating turmoil across the world. It is considered a Pandemic disease globally.

The source of origination of novel coronavirus or COVID-19 is important to contain the infection. Coronaviruses are zoonotic pathogens that started infecting animals and then transmitted to humans through spillover. For example, MERS-CoV or Middle East Respiratory Syndrome-related Coronavirus, first detected in Saudi Arabia in 2012, was transmitted from camels. Similarly, SARS-CoV or Severe Acute Respiratory Syndrome-related Coronavirus, first identified in China in 2003, was possibly transmitted through civet cats.

The original animal reservoir of COVID-19 is unknown. However, some researchers have proclaimed that bats are the most likely reservoir of COVID-19, but there are not enough pieces of evidence to prove the fact. 


Let us have a closer look at the symptoms of coronavirus disease. World Health Organization (WHO), have proclaimed that the most common symptoms of COVID-19 are: 

  1. Fever

  2. Tiredness

  3. Dry cough, and

  4. Difficulty in breathing (in severe cases)

    It may take 1 to 14 days of time to develop the symptoms in the person who is already infected with the virus. According to WHO, older people and people with pre-existing medical problems like high blood pressure, heart problems or diabetes, are more likely to experience severe symptoms of COVID-19.

    How it spreads?

    1. Person-to-person

    Coronaviruses can be transmitted from person-to-person. People can catch the infection through respiratory droplets that are released when a person coughs or sneezes. When you come in contact with the infected person, the viruses can make an entry into your body through droplets of saliva or discharge.

    1. From touching contaminated surfaces and objects

    The respiratory droplets exhaled by the infected person can land on the surfaces and objects. If you accidentally touch these surfaces and objects and then touch your eyes, nose or mouth with the same hands, you are at higher risk of getting the infection.

    There are also assumptions that COVID-19 can spread through air and feces. However, there are no pieces of evidence yet reported that can claim the facts.

      • Some travelers are using antipyretic (medication used to lower body temperature) to avoid detection through screen tests. Thus, it may not restrict the importation of infected people.
