CEEID formally established in 2018. This Centre fully take the advantage in different research fields of CAS, make full use of the research platforms for Emerging Infectious Disease (EID) of Institute of Microbiology (IMCAS), Center for Influenza Research and Early-warning (CASCIRE), the Institute Pasteur of Shanghai (IPSCAS) and the Bio-safety level 4 (BSL-4) laboratory in Wuhan Institute of Virology (WIVCAS), to build a national research cooperation and communication center with all developing countries. The CEEID will focus on the frontier scientific questions in the field of EID and the strategic demands for the biological safety of our country. The specific aims are to explore the evolution and pathogenesis of the emerging/re-emerging pathogens, to understand the mechanisms of interspecies transmission of viral pathogens and the interaction between pathogen and host cells, as well as infection and T/NK cell immunity, and to develop novel therapeutic agents.
