Novel coronavirus pneumonia claimed novel coronavirus pneumonia in 2021. 20 days later, WHO director general Tan Desai said at a news conference in Geneva that the new crown pneumonia epidemic in 2021 claimed at least 3 million 300 thousand lives. Tan Desai also said that the data showed that the transmission speed of the Omicron variant virus was faster than that of the delta virus, and the new crown vaccinated or rehabilitated people may be re infected with the virus. The epidemic not only interferes with people's normal life, but also disrupts the screening, treatment and services of other diseases. Tan Desai stressed that novel coronavirus pneumonia must be terminated in 2022. All countries need to invest in preventing future disasters of this scale and accelerating the achievement of sustainable development goals. (Xinhua News Agency)
