What is a novel coronavirus?
section_content: A novel coronavirus is a new coronavirus that has not been previously
identified. The virus causing coronavirus disease 2019 (COVID-19), is not the
same as the coronaviruses that commonly circulate among
humans and cause mild illness,
like the common cold.
A diagnosis with coronavirus 229E, NL63, OC43, or HKU1 is not the same as a
COVID-19 diagnosis. Patients with COVID-19 will be evaluated and cared for
differently than patients with common coronavirus diagnosis.

Reviewer feedback on this answer:
Mentioned that the coronavirus is new but not where it came from.
This answer does not provide the origin of the coronavirus as asked in the question, instead, it is an explanation of coronavirus diagnosis and the definition of novel coronavirus.

section_headers: How COVID-19 Spreads
What is the source of the virus?
section_content: COVID-19 is caused by a coronavirus called SARS-CoV-2. Coronaviruses are a
large family of viruses that are common in people and many different species
of animals, including camels, cattle, cats, and bats. Rarely, animal
coronaviruses can infect people and then spread between people. This occurred
with MERS-CoV and SARS-
CoV, and now with the virus that causes COVID-19. The SARS-
CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV. All three of
these viruses have their origins in bats. The sequences from U.S. patients are
similar to the one that China initially posted, suggesting a likely single,
recent emergence of this virus from an animal reservoir. However, the exact
source of this virus is unknown.
More information about the source and spread of COVID-19 is available on the
Situation Summary: Source and Spread of the
Virus.

Reviewer feedback on this answer:
Clearly describes the zoonotic origins of the virus and that it originated in China.
This answers the question directly by providing detail explanation and information on the origin of coronaviruses including the Covid-19.

for ‘corona,’ ‘VI’ for ‘virus,’ and ‘D’ for disease. Formerly, this disease
was referred to as “2019 novel coronavirus” or “2019-nCoV”.
There are many types of human coronaviruses including some that commonly cause
mild upper-respiratory tract illnesses. COVID-19 is a new disease, caused be a
novel (or new) coronavirus that has not previously been seen in humans. The
name of this disease was selected following the World Health Organization
(WHO) best practiceexternal iconexternal

for naming of new human infectious diseases.
