section_headers: What is a coronavirus?
section_content: Coronaviruses are a large family of viruses which may cause illness in animals
or humans. In humans, several coronaviruses are known to cause respiratory
infections ranging from the common cold to more severe diseases such as Middle
East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).
The most recently discovered coronavirus causes coronavirus disease COVID-19.

Reviewer feedback on this answer:
This answer kind of states what the coronavirus is, but not really what the symptoms are.
This information does not answer the question. This information explains what coronaviruses are and known diseases that the viruses had cause. It does not provide any information on symptoms associated with the Covid-19.

Answer passage (source: WHO):
page_title: Q&A on coronaviruses (COVID-19)
section_headers: What are the symptoms of COVID-19?
section_content: The most common symptoms of COVID-19 are fever, dry cough, and tiredness.
Other symptoms that are less common and may affect some patients include aches
and pains, nasal congestion, headache, conjunctivitis, sore throat, diarrhea,
loss of taste or smell or a rash on skin or discoloration of fingers or toes.
These symptoms are usually mild and begin gradually. Some people become
infected but only have very mild symptoms.
Most people (about 80%) recover from the disease without needing hospital
treatment. Around 1 out of every 5 people who gets COVID-19 becomes seriously
ill and develops difficulty breathing. Older people, and those with underlying
medical problems like high blood pressure, heart and lung problems, diabetes,
or cancer, are at higher risk of developing serious illness. However, anyone
can catch COVID-19 and become seriously ill. People of all ages who experience
fever and/or cough associated withdifficulty breathing/shortness of breath,
chest pain/pressure, or loss of speech or movement should seek medical
attention immediately. If possible, it is recommended to call the health care
provider or facility first, so the patient can be directed to the right
clinic.
