In December 2019, some new and unexplained cases of pneumonia were found in Wuhan, Hubei province, China, and were later named as coronavirus disease 2019 by the World Health Organisation. The number of cases increased rapidly, and the virus spread continuously. Tens of thousands of medical staff throughout the country have since rushed to Wuhan to provide intensive medical treatment.
