Lyme Disease Data File
To facilitate the public health and research community’s access to NNDSS data on Lyme disease, CDC has developed a public use dataset. Based on reports submitted to CDC, this dataset provides the number of reported cases by county for the years 1992-2006, in three 5-year intervals. County tabulation is by American National Standard Institute (ANSI) [formerly Federal Information Processing Standard (FIPS) codes]. ANSI county codes ending in “999” represent “unknown” county of residence within each state. More recent county-level case counts are not publicly available at this time.
