What is Corona virus disease in Humans?
Corona viruses are a type of virus that causes respiratory infections ranging from the common cold to more severe diseases.Corona viruses are named for the crown-like spikes on their surface.
There are many different kinds, and some cause death. A newly identified type of this virus has caused a recent outbreak of respiratory illness now called COVID-19 that is started in Wuhan city of China.
In 2002, the Corona virus killed 774 humans in China and affected a total of 8098 people.
From where the Corona virus disease (COVID-19) Started?
A bat left Corona virus in its dung in some part of China ,The virus dropped to the forest floor where a Pangolins animal got its virus from the waste .The virus spread to other animals.The infected animals were eaten by humans and the disease began to spread to humans and started to spread in the world.
Professor Andrew Kingham of the Zoological Society of London said that Scientists are trying to link these phenomena like spies.They say that the virus can occur in many types of animals in the forest, especially bats in which several types of corona virus are found.
Authorities in China have banned their citizens from coming to the city of Wuhan, So far thousands of people have been killed by a deadly new virus which is named as COVID-19 .
How does Corona virus Disease spread in Humans?
Recent information have shown that COVID-19 may be passed from person to person.Like cold and flu bugs, the virus can spread via droplets when a person coughs or sneezes. The droplets from sneezes land on surfaces and are picked up on the hands of others and spread further disease. People catch the corona virus when they touch their infected hands to their mouth, nose or eyes.
COVID-19 has been detected globally in people throughout China and in over 100 other countries, including the United States and Canada.It follows that the single most
important thing you should do to protect yourself is keeping your hands clean by washing them frequently with soap and water or a hand sanitising gels.
The spread of this new Corona virus is being monitored by the Centers for Disease Control (CDC), the World Health Organization (WHO).

229E (alpha corona virus)
NL63 (alpha corona virus)
OC43 (beta corona virus)
HKU1 (beta corona virus)
MERS-CoV (the beta corona virus that causes Middle East Respiratory Syndrome, or MERS)
