Reportable Medical Events are documented in the Disease Reporting System internet by health care providers and public health officials throughout the Military Health System for monitoring, controlling, and preventing the occurrence and spread of diseases of public health interest or readiness importance. These reports are reviewed by each service’s public health surveillance hub. The DRSi collects reports on over 70 different RMEs, including infectious and non-infectious conditions, outbreak reports, STI risk surveys, and tuberculosis contact investigation reports. A complete list of RMEs is available in the 2022 Armed Forces Reportable Medical Events Guidelines and Case Definitions.1 Data reported in these tables are considered provisional and do not represent conclusive evidence until case reports are fully validated.

Table of Reportable Medical Events for April 2025

Total active component cases reported per week are displayed for the top five RMEs for the previous year. Each month, the graph is updated with the top five RMEs, and is presented with the current month’s (April 2025) top five RMEs, which may differ from previous months. COVID-19 is excluded from these graphs due to changes in reporting and case definition updates in 2023.

Top 5 Reportable Medical Events by Calendar Week, Active Component (May 11, 2024–May 3, 2025). This figure comprises five lines on the horizontal, or x-, axis that depict case counts for the five most frequent reportable medical event conditions among active component service members during the past 52 weeks. Chlamydia remains the most common reportable medical condition, with counts consistently around 300 cases per week. Gonorrhea was the second-most common reported condition, averaging approximately 45 cases per week, with an uptick in the last week. Since the beginning of 2025, norovirus was consistently the third most frequent condition, but declined to fourth position in the final two weeks of April, eclipsed by heat illnesses, although norovirus had a higher weekly average, around 20 cases, while heat illnesses only averaged 13 or so, for the entire month of April. Syphilis averaged just under eight cases per week in April.
