Ladies and gentlemen, friends from the media, good afternoon. Welcome to this press conference held by the State Council Information Office (SCIO). Since the COVID-19 outbreak, Chinese scientific researchers and experts have been going all out to make scientific breakthroughs in the prevention and control of COVID-19. Today, we invited three scientists to meet with you and brief you on the scientific research into COVID-19. They are: Jin Qi, president of the Institute of Pathogen Biology at Chinese Academy of Medical Sciences; Yan Jinghua, researcher at the Institute of Microbiology at the Chinese Academy of Sciences; and Wang Guiqiang, director of the infectious disease department of Peking University First Hospital. They will first introduce themselves before taking your questions.
