Michael Ryan, executive director of the World Health Organization (WHO) health emergencies program, speaks at a press conference in Geneva, Switzerland on Feb. 13, 2020. The surge in the number of new confirmed cases in China came after a change to include any suspected cases with pneumonia-related computerized tomography scan results, rather than relying on laboratory tests to confirm cases. The figure sounds gloomy, but life is the top priority. Based on more knowledge of the virus, the revised diagnostic procedure aims at helping patients get treatment more quickly and improving the chances of recovery. The spike "does not represent a significant change in the trajectory of the outbreak," as Michael Ryan has said. (Xinhua/Chen Junxia)
