On January 7, 2020, Chinese scientists isolated a previously unknown coronavirus in the patients, and on January 12, the scientists made its genetic sequence available to WHO and international partners. WHO initially named the virus 2019- nCoV and later renamed it severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus can cause a disease in humans that WHO is calling coronavirus disease 2019 (COVID-19)."
