Reportable Medical Events (RMEs) are documented in the Disease Reporting System internet (DRSi) by health care providers and public health officials throughout the Military Health System (MHS) 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 5 RMEs for the previous year. Each month, the graph is updated with the top 5 RMEs, and is presented with the current month’s (July 2025) top 5 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 Five Reportable Medical Events by Calendar Week, Active Component (August 10, 2024–August 2, 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 remained the most common reportable medical condition, with counts consistently around 300 cases per week. Heat illnesses rose throughout the month, exceeding 100 cases by month’s end, continuing to outnumber gonorrhea, which was the third most common condition. Cases of both norovirus and campylobacteriosis were again the fourth- and fifth most common reportable medical events in July, with approximately 10 cases per condition each week.
