NOTE: Rates per 100,000 population are calculated based on population estimates of MSM adapted from Grey et al, JMIR Public Health Surveill, 2016. See Technical Notes for more information on syphilis case reporting. 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; 2021 data from Maryland have been suppressed in this table. 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. |
