Results: A total of 470 students were included in the study. The overall correct answer rate of the COVID-19 knowledge questionnaire was 74.43% and total score of the HRQoL was 72.50 (14.85). 61.7% of the students were agreed that COVID-19 will finally be successfully controlled, 44.3% had confidence that Iran can win the battle against the COVID-19, and 92.6% agreed that Quarantine will reduce the prevalence of COVID-19. Most of them adhered to health protocols and about a relation between HRQoL and knowledge we have a weak positive and unsignificant correlation between them (r = 0.05, = 0.27).

Conclusions: TUMS students showed expected levels of knowledge, proper attitudes, and preemptive practices regarding COVID-19, whereas COVID-19 outbreak substantially affected the physical and mental health but, the students were in a way better physical health rather than mental.
