          Coronavirus or Covid-19


Corona virus is a type of virus that can infect the respiratory tract of humans and other birds.

It is an RNA virus. The earliest reports of a coronavirus infection in animals occurred in the late 1920s,when an acute respiratory infection of domesticated chickens emerged in North America.

Arthur Schalk and M.C. Hawn in 1931 made the first detailed report which described a new respiratory infection of chickens in North Dakota. The infection of new-born chicks was characterized by gasping and Leland David Bushnell and Carl Alfred Brandly isolated the virus that caused the infection in 1933. The virus was then known as infectious bronchitis virus (IBV).

Nevertheless, it became most popular in 2020, when a new type of corona virus became epidemic.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. It was first reported on November 19, 2019, from a market in Wuhan, China.

Since then it has spread rapidly and in 2020 it spread like a plague around the world.

The World Health Organization named this novel corona virus Covid-19 through discussion.

The corona virus looks round on an electron microscope and is surrounded by special spikes.


These spikes are made of special proteins. Since the molecular structure of this protein is somewhat similar to that of human proteins, it is easily transmitted to human proteins.

so this spikes helps the virus infects the cells of the human body. When infected with the coronavirus, it initially causes diseases like pneumonia. But in the real sense it is not pneumonia.

It is a new virus and has spread rapidly recently, so its characteristics are not known specifically. The coronavirus has been known to change its form over and over again.

That is why different types of indefinite symptoms appear at different times. No disease symptoms are ever seen. It spreads rapidly in older people and causes death. However, it is known to spread to everyone, including children, but the mortality rate is much lower among young people.


No antidote to this virus has yet been discovered. So prevention is the best and the only hope to keep yourself safe. SO  scientists and doctors have suggested wearing a mask to prevent from the virus. Those infected with the virus need to be quickly identified and isolated. If everyone stay house and avoids crowds, it is possible to prevent the spread of the corona virus.
