Early January ***0, a novel coronavirus (SARS-CoV*2, formerly known as
****-nCoV) was identified as the infectious agent causing an outbreak of
viral pneumonia in Wuhan, China, where the first cases had their symptom
onset in December ***9.
Coronaviruses are enveloped RNA viruses that are distributed broadly
among humans, other mammals, and birds and that cause respiratory,
enteric, hepatic, and neurologic diseases.Six coronavirus species are
known to cause human disease. Four viruses***9E, OC*3, NL*3, and
HKU1 are prevalent and typically cause common cold symptoms in
immunocompetent individuals. The two other strains severe acute
respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory
syndrome coronavirus (MERS-CoV) are zoonotic in origin and have been
linked to sometimes fatal illness.
Coronaviruses are zoonotic, meaning they are transmitted between animals
and people. Common signs of infection include respiratory symptoms,
fever, cough, shortness of breath and breathing difficulties. In more severe
cases, infection can cause pneumonia, severe acute respiratory syndrome,
kidney failure and even death.
Standard recommendations to prevent infection spread include regular
hand washing, covering mouth and nose when coughing and sneezing,
thoroughly cooking meat and eggs. Avoid close contact with anyone
showing symptoms of respiratory illness such as coughing and sneezing.
