The study defi nes and analyses the organization of the concept of Pandemic. According to psychological interpretation the concept of Pandemic is a mental model that refl ects objectifi ed and subjective-evaluative highlighters and infl uences the coping behaviour in a specifi c diffi cult situation. The diagnostic complex included three open-type tasks (a directed associative experiment, problem formulation, and a visual portrait of the concept). The assumption about the specifi cs of mental representations of the pandemic in medical workers and sales assistants was tested. The results demonstrated that sales assistants had a generalized mental model of the pandemic (a disease around the world) and described diff erent problems in studying the pandemic. Medical specialists working with COVID-19 patients had more diff erentiated mental representations of the pandemic; they were better aware of the medical and health problems of the pandemic. Mental representations of pandemic among participants included objectifi ed and negative emotional-evaluative descriptions.
