The chapter I introduce to Coronavirus ( COVID-19) are including source, mores, and the new coronavirus are from China. Also discuss, what is a coronavirus, Origin of the virus, How is it transmitted, The group most at Risk, Coronavirus symptoms, Coronavirus Diagnosis, 

How dose PCR testing for COVID  -19 work? ,  Coronavirus Treatment and discuss common sing and syndrome of coronaviruses.

• Coronavirus are a family of RNA virouses in Nidovirales order .
• This virus is a significant viral pathogen in humans and animals.
• In the word coronavirus prefix, corona comes to form the Latin word for crown and due to name for Crown Like the appearance of virus.
• There are four classifications are coronaviruses 

1.  Alpha
2.  Beta
3.  Gamma 
4.  Delta

• Human coronaviruses are alpha and beta coronavirus. So the coronaviruses are talking about are classification to alpha and beta.
• Coronaviruses are a medium size virus that developing a positive-stranded RNA. In coronaviruses are very large viral RNA genome known.

In December 2019, there is a cluster of pneumonia cases in china. Invitation found there is caused by a previously unknown virus. Now Named 2019 Novel coronavirus.

Coronaviruses are large groups of viruses, they consist of the core of genetic material and surround of enveloped with protein spikes.

They are different types of coronaviruses - that caused respiratory and some times Gastrointestinal syndrome.

 Respiratory disease can range from the common cold to pneumonia. Most people the syndrome generally mild disease.

 However, some types of coronaviruses can cause severe disease. These include ---

SARS -COV-2002/2003 (Severe Acute Respiratory Syndrome)

•  Guangdong province of China.
•  It's a Beta coronavirus.
•  Transmitted from bats to civets to humans.
•  Began in February 2003 and the outbreak lasted until July 2003.
•  More than 8000 total cases, 774 deaths.

 MERS -COV-2012 (Middle East Respiratory Syndrome)

•  It started in Saudi Arabia.
•  It's a Beta coronavirus.
•  Transmitted from camels to humans.
•  More than 2400 cases, 858 deaths.

 COVID--2019 (Novel coronavirus)

•  Wuhan hubel province of china.
•  The seventh coronavirus found to cause illness in humans.
•  Its a Novel beta coronavirus.
•  Transmitted from snakes but more likely from bats.

 NOTE:- But not sure that exact cause of transmission to the human body and don't have any proper evidence to prove, who is the host for this transmission.

Origin of the virus:

Coronaviruses circulate in a range of animals. Some times of there viruses transmission animals to humans. This is called spillover, it could do a range of factors such as a mutation in the virus or increase contact between humans and animals. For example, MERS - COV from cat .2019 - NCOV Nobel coronavirus is known yet.

How is it transmitted:

 Inexact dynamics yet to be determined in general respiratory viruses are usually transmitted through droplets created in infection person cough or sneeze or sometimes its other contamination with virus.

The group most at Risk: 

 Those in close contact with animals such as az living animals market workers and those are caring for people with an infection such as family members or healthcare workers.

Coronavirus symptoms:

Some numbers of symptoms ranging from mild to severe. That can be fever, respiratory symptoms such as cough and shortness of breath. In more severe cases, there is pneumonia, kidney failure, and Death. The mortality rate is not known yet.

Coronavirus Diagnosis:

This infection can diagnosis by PCR ( Polymerase Chain Reaction). This test identifies the virus paste Genetic fingerprint.

How dose PCR testing for COVID -19 work?

Coronavirus Treatment:

There is no specific medication for viruses and currently no vacation to protect again the virus. Treatment and vacation are in development.

How do you prevent transamination of virus

This new virus currently has limited geographic spread. How ever, these are the number of standard hygienic practices that have been recommended to protect against the infection and further spared.

• Covering mouth and nose by masks, tissue, pocket hanker chief, etc.
•  Avoiding close contact with those who are sick.
•  The appropriated use masks and PPE ( Personal protective equipment) especially in health care settings.
•  Washing hand regularly with sope, water, and alcohol-based hand washing.
•  Avoiding unnecessary contact with animals.
•  Before eating animals product to cook thoroughly.

 NOTE:- Stay home if you feeling unwell and you have a fever, cough difficulty breathing seek medical care early. And insure your previous travel history with your healthcare provider.
