The pandemic is a new, surprising situation that shows the quality of life in a completely different dimension. Studies show that the quality of life of people infected with SARSCov2 has signifi cantly decreased both psychologically and physically. Covid 19 disease caused by coronavirus SARS-CoV-2 has been shown to be a complex pathogenic disease with high mortality rates, especially in the elderly, but many serious cases and deaths occurred in young people. The aim of the study was to investigate whether COVID 19 disease signifi cantly affects the quality of life of those affected. The method used for online diagnostics was the EQ-5D-3L Quality of Life Questionnaire and a modifi ed BAT questionnaire. Studies have shown that the quality of life of the respondents was at an average level. Pain/discomfort and anxiety/depression were the most frequently indicated domains. A statistically signifi cant strong relationship between the demographic variables age, gender and morbidity and quality of life after the disease was shown. Similarly, the effects of hospital stays and concomitant illnesses affecting quality of life were investigated. The results can feed into medical practice, therapy, education and therapy of mental health, and the applied research model can be considered useful and useful to continue research.
