With the COVID-19 outbreak, it appears that social research to better understand how people react to epidemics, particularly this one, is a necessity. A lesser-known societal feature of COVID-19 is the trust of Corona patients in modern medical institution. The current study addresses this issue. This study drew on institutional trust theories, most notably Giddens' theory of abstract systems trust. In this study, the qualitative method was applied. Thematic analysis is a qualitative research method which was used. Braun and Clarke's thematic analysis was employed to analyze the data. The statistical population for this study is comprised of Covid-19 patients who have been infected with the virus between the Covid-19 virus outbreak in Iran and September 2020, and 21 of them were chosen through a purposive sampling method. Semi-structured interviews were conducted with these patients. According to the research findings, Corona patients' opinions can be classified into three categories: 'medical science and expertise', 'hospital environment,' and 'medical staff,' with each category containing sources of trust and distrust. The article delves deeper into sub-themes and other details. Among the COVID-19 patients who have been interviewed, there appears to be a boost in public trust in medical personnel. While these patients' trust in medical science and expertise, as well as in the hospital environment, has eroded.
