ABSTRACT
PURPOSE OF REVIEW: The ability to effectively prepare for and respond to the psychological fallout from large-scale disasters is a core competency of military mental health providers, as well as civilian emergency response teams. Disaster planning should be situation specific and data driven; vague, broad-spectrum planning can contribute to unprepared mental health teams and underserved patient populations. Herein, we review data on mental health sequelae from the twenty-first century pandemics, including SARS-CoV2 (COVID-19), and offer explanations for observed trends, insights regarding anticipated needs, and recommendations for preliminary planning on how to best allocate limited mental health resources. RECENT FINDINGS: Anxiety and distress, often attributed to isolation, were the most prominent mental health complaints during previous pandemics and with COVID-19. Additionally, post-traumatic stress was surprisingly common and possibly more enduring than depression, insomnia, and alcohol misuse. Predictions regarding COVID-19's economic impact suggest that depression and suicide rates may increase over time. Available data suggest that the mental health sequelae of COVID-19 will mirror those of previous pandemics. Clinicians and mental health leaders should focus planning efforts on the negative effects of isolation, particularly anxiety and distress, as well as post-traumatic stress symptoms.
