* Cases are not displayed if the variable used to identify sex of sex partners is complete for <70% of male cases. ND = Not displayed. NOTE: Rates per 100,000 population are calculated based on population estimates of MSM adapted from Grey et al, JMIR Public Health Surveill, 2016. 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; 2021 data from Maryland have been suppressed in this table. |
