This is a general overview and status of places affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus which causes coronavirus disease 2019 (COVID-19) and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 were identified in Wuhan, the capital of the province of Hubei in China in December 2019. It spread to other areas of Asia, and then worldwide in early 2020.
The figures presented are based on reported cases and deaths. While in several high-income countries the ratio of total estimated cases and deaths to reported cases and deaths is low and close to 1, for some countries it may be more than 10[7] or even more than 100.[8] Implementation of COVID-19 surveillance methods varies widely.[9]
