The Medical Surveillance Monthly Report—or MSMR—published continually since 1995, is the peer-reviewed journal of the Armed Forces Health Surveillance Division. For more than 30 years, MSMR has transformed complex military health data into credible, actionable information for clinicians, commanders, public health professionals, and policy-makers. MSMR publishes monthly reports describing the incidence, distribution, impact, or trends of illness and injuries among members of the U.S. Armed Forces and other beneficiaries of the Military Health System.

The October 2026 issue of MSMR  presents two full reports, including a case study, in addition to one brief report and a Surveillance Snapshot. The issue features a study of flea-borne typhus fever in the U.S. military; followed by a case report of a delayed onset Plasmodium vivax malaria infection after exposure near the Demilitarized Zone in the Republic of Korea: with brief report of 2025-2026 influenza season vaccine effectiveness estimates against outpatient cases among U.S. active component service members; complemented by a Surveillance Snapshot on the challenges of statistical power in high coverage populations when assessing influenza vaccine effectiveness trends among U.S. active component service members; and concludes with a quarterly report of the most frequent reportable medical events within the Military Health System.
