COVID-19 is an infectious disease caused by a new strain of coronavirus known as SARS-CoV2 (Severe Acute Respiratory Syndrome Coronavirus 2).This name was chosen because the virus is genetically similar to the coronavirus responsible for the outbreak of SARS in 2003. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.
