ABSTRACT
Objective The purpose of this study was to determine the prevalence and differences in etiology, clinical manifestations, and psychological activity of coronavirus disease-19 (COVID-19) among patients. Results We recruited 90 subjects, 30 were healthy controls, 30 were patients with moderate infection, and 30 were patients with severe/critical infections. No significant differences were noted in the sex ratio, mean age, body mass index, or blood type; however, the history of exposure of the patients with COVID-19 compared with healthy controls was noteworthy. The erythrocyte sedimentation rate, as well as the levels of C-reactive protein and serum amyloid A (SAA) were all increased. In terms of mental health, there were significant differences in the worry scores between severely and moderately infected patients and healthy controls. There was a significant difference in depression scores between patients with moderate infection and healthy hypertension, and there was also a significant difference in dream worry scores. Analysis of the Mini-Mental State Examination scores showed that for patients with moderate infection, the depression score was moderately and positively correlated with the dream anxiety score. For patients with severe infection, the anxiety score was positively correlated with the dream anxiety score, and the depression score was moderately and positively correlated with the dream anxiety score. Conclusion Patients with severe infection showed increased pain and sputum in the pharyngeal area compared with patients with moderate infection. Patients with blood type A may be more susceptible to COVID-19, and lymphopenia may indicate worsening of COVID-19.
