*Due to software transition STD data since 2014 are not comparable with those in previous years. Use of illness onset date in data aggregation for cases other than STD or TB (since Jan-2013) causes changes in cases reported here from previously released reports. Numbers are provisional including confirmed, probable and suspect cases that are reportable to CDC. HIV/AIDS/TB case counts provided on a quarterly basis. Data suppression denoted by ‘.’ applies if number of cases <5. Monthly disease total (excluding STD and TB cases)=181(reported total=1520). Monthly congenital syphilis cases (suppression applied) for 2015-2017 were 0,.,.(YTD totals of .,.,7) respectively.
~Zika case definitions added in 2016.

~~Confidence intervals (not shown) for the monthly disease incidence rates provided a basis for an informal statistical test to determine if the current monthly rates changed significantly from those of the previous 5 years aggregated. Text in green where rates decreased and in red where rates increased. Statistically significant changes indicated by ‘X’ (rate comparisons made if 5+ cases reported in the current month of this year or previous 5 years aggregated).
