简要总结
A pneumonia of unknown cause detected in Wuhan, China was first reported to the WHO Country Office in China on 31 December 2019. The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020. The spread and severity of the disease is variable from one country to another. Our team as well as many reports suggested that in some countries a " Flu like illness but much worse" was described in October, November and early in December before the WHO announcement. Was it COVID-19?
