In this contribution, we respond to a letter in Omega: Journal of Death and Dying by Doka. Signatories of this letter to the President of the United States convey concerns that deaths during the COVID-19 pandemic will lead to a higher prevalence of severe and persistent grief, i.e., prolonged grief disorder. We support their call to action to direct government funding to helping those who develop this condition during the COVID-19 pandemic. However, we think that concerns about prolonged grief disorder during the pandemic can be more convincingly conveyed by firmly embedding such concerns within scientific literature. Therefore, we highlight prior scientifically informed opinion pieces from various international researchers who voiced similar concerns in the early months of the pandemic. Additionally, we provide an overview of pioneering empirical research elucidating whether prolonged grief disorder and related mental health problems will become more prevalent during the pandemic.
