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:
The answer does not tell me where the virus began or originated. The answer only talks about the symptoms of the virus.
This response does not address the question of where the virus comes from. It merely specifies that this strand of the virus is not the same as other strands of corona viruses. It doesn't address the question at all.

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:
The answer directly tells me where the virus originates from, which is primarily in bats. It also mentions the country of China, which is where the virus was first discovered. Therefore, this is an excellent answer that does not need any further improvements.
The response indicates, "the exact source of this virus is unknown". It hints that the virus might have animal origins (ie: come from bats) but ultimately says the source is unknown. It is unclear by the question though, if the person asking the question is looking for a geographic location of where the virus comes from or not.

Why is the disease being called coronavirus disease 2019, COVID-19?
section_content: On February 11, 2020 the World Health Organization
announced an
official name for the disease that is causing the 2019 novel coronavirus
outbreak, first identified in Wuhan China. The new name of this disease is
coronavirus disease 2019, abbreviated as COVID-19. In COVID-19, ‘CO’ stands
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
icon
for naming of new human infectious diseases.

Reviewer feedback on this answer:
Nowhere in the response does the answer address the question of where does the virus come from. It basically describes how the virus got its name but mentions nothing of the source of the virus.
The answer does not indicate where the virus came from. The answer only talks about where the virus got its name, rather than where the virus began to spread.
