NOTE: See Technical Notes for information on syphilis, gonorrhea, and chlamydia case reporting, including information on the variables shown in this table. This report includes data from years that coincide with the COVID-19 pandemic, which introduced uncertainty and difficulty in interpreting case data. See Impact of COVID-19 on STIs for more information. Tennessee transitioned STI surveillance information systems in September of 2023 which may have impacted the overall case counts. Caution should be applied in interpretation of these data.
