Recovery-phase symptoms after COVID-19 infection and anxiety levels among college students.

Objective: This study examines the relationship between physical symptoms during the recovery phase after COVID-19 infection and anxiety levels among college students, with the aim of providing empirical evidence for post-pandemic mental health screening and health management in universities. Methods: The study used online survey data collected from college students in March 2023. After excluding straight-line responses, 394 valid questionnaires were retained. Among 372 students with a clear infection status, we examined the association between confirmed COVID-19 infection and anxiety. Among 298 students with confirmed infection, we further analyzed the associations of the number of physical symptoms during recovery, recovery time, and specific physical symptoms with anxiety. Results: Confirmed COVID-19 infection itself was not significantly associated with a higher anxiety level. Among infected students, however, the number of physical symptoms during recovery was positively associated with higher anxiety levels, whereas recovery time was not significantly associated with anxiety level. Analyses of specific symptoms showed that memory decline and chest pain were significantly associated with higher anxiety levels. Conclusion: Post-infection mental health screening in universities should not focus only on whether students have been infected. Greater attention should be paid to the burden of physical symptoms during recovery. Symptom count, cognitive changes, and chest discomfort may serve as useful supplementary indicators for post-infection follow-up and psychological risk identification.
