Metaphor provides an important intellectual tool for communication about intense disease experiences. The present study aimed to investigate how COVID-19-infected persons metaphorically frame their lived experiences of COVID-19, and how the pandemic impacts on their mental health burden. In-depth semi-structured interviews were conducted with 33 patients afflicted with COVID-19. Metaphor analysis of patient narratives demonstrated that: (1) COVID-19 infection impacted patient conceptualization of themselves and the relationship between the “self” and the body, as well as social relationships. (2) Metaphors relating to physical experience, space and time, and integrative behaviors tended to be used by COVID-19 patients in a negative way, whereas war metaphors, family metaphors, temperature metaphors, and light metaphors were likely to express positive attitudes. (3) Patients preferred to employ conventional metaphors grounded on embodied sensorimotor experiences to conceptualize their extreme emotional experiences. This study has important implications with respect to the therapeutic function of metaphors in clinical communication between healthcare professionals and COVID-19 patients.
