NOTE: See Technical Notes for more information on chlamydia case reporting and on interpreting case counts and rates in US territories. 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. Due to a network security incident in December 2021, the Maryland Department of Health could not finalize their 2021 STI case notification data. Although 2021 data from Maryland are included in national and regional case counts and rates displayed in this table, state-specific data have been suppressed. 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.
