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.

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 (June 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.

Figure. Top 5 Reportable Medical Events by Calendar Week, Active Component, June 13, 2024–June 30, 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. Heat illnesses rose throughout the month and surpassed gonorrhea early in the month as the second most common condition. Gonorrhea, the third most common reported condition in June, had the exact same number of cases as in the prior month. Cases of both norovirus and campylobacteriosis declined consistently throughout the month of June, but still surpassed syphilis (which does not appear on the graph) as the fourth- and fifth most common reportable medical events in June.
