* The top 70 counties and independent cities ranked in descending order by number of cases reported in 2016 then by rate are displayed.
NOTE: Relative rankings of counties may be impacted by completeness of the variable used to identify county. In 2016, the variable used to identify county was complete for ≤95% of cases in Massachusetts. See Appendix A1.4 for more information.
County was misclassified in the 2016 Alabama STD morbidity data resulting in inaccurate county-level case counts and rates. Tables will be updated when corrected data are available.
