Project Tycho: Historical Disease Data

Project Tycho is funded by NIH and the Bill and Melinda Gates Foundation. It has taken historical data from the National Notifiable Diseases Surveillance System (NNDSS) and created count data for diseases by location for the 125 year history of the surveillance system. Three levels of data have been made available to users from the Project Tycho website.

Other useful resources:

  • Materials and Methods: Digitication of US Weekly Surveillance Reports between 1888 and 2011
  • Preliminary State Reports (scroll down for access – here’s an example for Michigan)
  • What does Tycho stand for?
  • And, here is a paper published in the New England Journal of Medicine based on these data. It estimates that over 100 million cases of contagious diseases have been prevented in the U.S. since 1924 by vaccination programs against polio, measles, mumps, rubella, hepatitis A, diphtheria, and pertussis (whooping cough).
