Project Tycho® is a project at the University of Pittsburgh to advance the availability and use of public health data for science and policy making. Currently, the Project Tycho® database includes data from all weekly notifiable disease reports for the United States dating back to 1888. These data are freely available to anybody interested. Additional U.S. and international data will be released twice yearly. Please register here to start using these data for your project!
