What is coronavirus?

Coronavirus is an epidemic disease. On 11 February 2020, the WHO declared the disease as COVID-19. It is also known as Sars-CoV-2. It stands for Severe Acute Respiratory Syndrome Coronavirus 2. The coronavirus originated in Wuhan city of China in December 2019. On 11 March 2020, the World Health Organization declared it an epidemic. According to the latest WHO (world health organization) report, there are 11,220,009 confirmed cases of infected people. Out of this, 1,615,483 people have been cured and 529,604 people from 215 countries have died. Its number is increasing day by day. There are 650,431 confirmed cases of infected people in India. Out of this, 394,411 people have been cured and 645 have died.

How did it start?

This virus seems initiated from a Wuhan seafood market, which has all types of wild animals such as snakes, bats, birds, rabbits, marmots, etc. which are operated illegitimately. Some reports say that COVID-19 is like a chain system that spread from animals to humans. That's why if anyone got infected with the virus; it could affect the n-number of peoples like as we can see in the below image:

In the earlier study of the coronavirus says that it is related to viruses seen in snakes. Still, the search is going on for the animal cause of Coronavirus. In the Wuhan institute, the team of virologist released a detailed document which claims that the coronavirus genetic makeup is 96% match to that of a virus found in bats. Some of the unpublished study claims that are the inherited systems of Covid-19 in pangolins are 99% matching to the human virus.

But the fact is that the first case of infected people from coronavirus has no connection at all to the Wuhan seafood market, and due to that, the same market was a blackout for sanitizing and inspection by 1 January 2020. But it seems that coronavirus was already started spreading outside the market itself. The WHO western pacific office claim that's the virus was also being spreading among humans on 21 January 2020, and they also have proof that when the medical staff has been infected with the Covid-19. Meanwhile, we have a proper sign that it will transfer from people to people like in China it was speared if someone got infected and in the current stage, it will be established all over the world.

Coronavirus is not air born, it is spread by the respiratory droplets, which is the liquid that comes from our nose, and that particle is reached to somebody's eyes, nose, or mouth. If it is contracted to the hard surface, that hard surface may get infected, if somebody touched it and then touch their eyes, mouth, and nose.

Covid-19 is not bacteria; it is ultimately a virus; that's why it can also spread in the different temperatures like we see that it spread in Northern China where the warmth is cold, and it spread in Singapore where the temperature is generally warm.

Firstly, it is recognized as SARS (Severe Acute Respiratory Syndrome), which discovered in Southern China in 2002 and affected around 26 countries and reported over 8,000 cases and 774 deaths.

But the present source of this epidemic was primarily anonymous; on 7 January 2020; the Chinese health authorities acknowledged that is was happen due to the strain of coronavirus, which was not encountered in humans before. But after five days, the Chinese government disclosed the genetic sequence of the virus, so that other countries or the territory could make their diagnostic kits, and now it was known as Sars-CoV-2.

Reports say that the most infected (around 45k) people from coronavirus in china found that:

• 80% of persons are infected having minor symptoms.
• And the other 13 % of people have been in severe condition.
• And another 4 % of people were in a dangerous condition, which has to face respiratory failure, various organ failures.
• And last 2-3% of people have confirmed death cases due to Covid-19.
