Johns Hopkins CEIRS is developing improved methods to rapidly identify circulating influenza strains during the flu season. To do so, human influenza virus strains in the United States and Taiwan are being tracked as part of an effort to build a database of influenza cases in real time from hospitals and other health care facilities. Such surveillance and tracking in a centralized database could aid in the development of influenza vaccines that better match the circulating seasonal strains. In addition, researchers are analyzing the impact of influenza virus infection on human respiratory epithelial cells to better understand how to control and treat influenza infections.

The CEIRS Centers generate influenza surveillance and sequence data available in the public domain and accessible for further research. The public databases listed below have further information about Johns Hopkins CEIRS projects, influenza viral sequences from research and surveillance studies, and animal surveillance data from Center sampling efforts.
