At our military treatment facility, we observed multiple cases of shingles in otherwise immunocompetent patients well before the CDC vaccination guidelines were issued. In our discussions with our patients, the only contributing factors to their development of shingles were their work/home stressors related to their peacetime military operations. Furthermore, through retroactive data collection, we discovered that every single shingles patient at our MTF did not meet the age-based vaccination requirement. In our poster presentation, we analyze stress during peacetime military operations and its potential contribution to waning immunity, leading to the subsequent reactivation of the latent Varicella-Zoster virus (VZV). Our presentation will feature two cases of shingles, one in a 34-year-old and one in a 38-year-old, which occurred within one week of each other. Utilizing Discern data, we will also present retrospective data of all local cases. We will also discuss stress in the military population in comparison to their civilian counterparts, how this stress can cause waning immunity, and ultimately reactivation of VZV. Furthermore, we will discuss the operational impacts that this disease can cause on flying status and non-flying duty restrictions.
