For exploring the impact of the Covid-19 on the mental health of the students, who have been stranded from Chinese universities, the study has made the use of the independent sample t-test and analysis of variance (one-way ANOVA). The findings show that Mental health of students stranded from universities negatively affected due to high level of anxiety, depression, and social anxiety due to pandemic. However, the level of anxiety, depression, and social anxiety has reduced to some extent as compare to earlier studies after the emergence of pandemic of COVID-19. The outbreak of COVID-19 has affected females more than males and the postgraduate students have a lower level of depression as compared to the undergraduate students because they have shown a higher level of mean and standard deviation values. Moreover, the depression level was high among the students of Natural and Applied sciences.
