NOTE: The COVID-19 pandemic has introduced uncertainty and difficulty in interpreting STD data collected during 2020 and 2021. See Impact of COVID-19 on STDs for more information. Due to a network security incident in December 2021, the Maryland Department of Health could not finalize their 2021 STD case notification data. Although 2021 data from Maryland are included in national data displayed in this table, state-specific data have been suppressed.
