The aim of this study was to describe and compare the lived experience of middle-aged people with the phenomenon of Covid-19 and quarantine experience in the first and second peaks of the disease. This qualitative study was done by descriptive phenomenological method. 10 middle-aged participants (41 to 65 years old) were chosen by purposive sampling method and interviewed in depth, during two peaks of corona in Iran. Data were saturated with 7 interviews and to make sure, 10 people were interviewed. Data obtained from the interviews were analyzed by the seven-step Colaizzi’s method. The present study achieved 10 main themes and 28 sub-themes. Key topics included first encounter, worries, beliefs, dealing, and the role of religion, family relationships, existential concerns, post-corona growth and the experience of infecting relatives. It seems that in the first peak of Corona, middle-aged people experienced anxiety, which over time, decreased by turning to religion, the principles of hygiene and avoidance. The remarkable point of the present study is that middle-aged people have experienced more acceptance of the crisis and the resulting situation than experiencing growth and change in the two corona peaks. In fact, middle-aged people try to adjust to their limitations and are less concerned about changing their lifestyle.
