The purpose of this study was to describe the early epidemiology and contact tracing challenges for Covid-19 infection in an overseas military and DoD population. From February 28, 2020 to April 27, 2020, patients who were diagnosed with Covid-19 infection completed a Centers for Disease Control Persons Under Investigation (PUI) form during their encounter with a medical provider. Positive results were forwarded to the Public Health Department. ⋯ Public Health guidelines for the USA may have varying relevance in an overseas location. Rapid case identification with on-site testing is critical to disrupt disease transmission. Preventive measures for Covid-19 infection have decreased incidence of influenza-like illness.

The coronavirus disease 2019 pandemic has exposed a health security gap within our nation and around the world. Recent national laws and policies have outlined the ends and means to improve health security. A decisive way is to achieve this objective is through health-related security cooperation efforts by increasing Health Services Support capacity.

The coronavirus-2019 (COVID-19) pandemic has significantly impacted global healthcare delivery. Brooke Army Medical Center (BAMC) is the DoD's largest hospital and a critical platform for maintaining a ready medical force. We compare temporal trends in patient volumes and characteristics in the BAMC emergency department (ED) before versus during the pandemic. ⋯ The BAMC ED experienced a significant decrease in patient volume during the COVID-19 pandemic starting in March 2020. This may have significant implications for the capacity of this facility to maintain a medically ready force.

Marines must complete an intensive Assessment and Selection (A&S) course before becoming a U.S. Marine Forces Special Operations Command (MARSOC) Raider. Following selection, marines are given training recommendations designed to maintain performance characteristics deemed relevant to successfully complete a rigorous 9-month Individualized Training Course (ITC). However, training strategies are individually implemented by the marine, and the time between the two courses is highly irregular, ranging between 2 months and 24 months based on operational factors related to military occupational specialty (MOS). The purpose of this study was to evaluate changes in performance between the completion of A&S and the start of ITC and to examine if the duration between courses and previous MOS influenced changes in performance. ⋯ Current training strategies appear effective at addressing performance deficits that occur as a result of A&S, while maintaining high levels of KF, KE, TE, TF, AC, and VO2max. However, pre-ITC students still exhibited AP deficits compared to active marine raiders, so forthcoming programming may benefit from an increased emphasis on AP. Assessment of additional selectees at these timepoints, as well as students before A&S may provide valuable information to MARSOC human performance specialists to develop programing, ultimately leading to a higher ITC graduation rate, increased force readiness, and decreased financial burden forcewide.

The submarine environment presents unique challenges in mitigating the spread of respiratory viruses because of the re-circulatory atmosphere and lack of ability to physically distance. The atmosphere of a submarine is periodically ventilated and continuously scrubbed. However, the air is recycled for months until the ship is able to ventilate. An outbreak of coronavirus disease 2019 (COVID-19) occurred on a U.S. Navy fast-attack nuclear submarine (SSN) with a crew of 128 personnel. ⋯ As expected, SARS-CoV-2 was able to spread rapidly among a submarine crew. In 11 days, the infection spread to 64 total crewmembers out of 128. Outbreaks such as these have played a role in future COVID-19 testing and mitigation protocols that have affected day-to-day operations.
