† The variable used to identify county, which is used to classify cases into MSAs, was complete for ≤95% of cases in a state contributing data to this MSA. See Technical Notes for more information.

‡ 2016 county data for Alabama have been corrected and may not match previous reports.

NOTE: Cases reported with unknown sex are not included in this table. County was misclassified in the 2017 District of Columbia STD morbidity data resulting in inaccurate county-level case counts and rates.
