Introduction: Folic acid, B12 and Iron play an important role in the pathogenesis of viral infections. Aim: The aim of the study is to determine the blood levels of Folate, B12 and Iron and to examine their relationship with prognosis in cases followed up by the COVID-19 pandemic service. Materials and Methods: The study was planned as a retrospective observational case-control study. In a period of approximately 3 months, 140 patients were screened retrospectively, 70 of whom were COVID-19 and 70 control cases. Cases <18 years of age, followed up in the Intensive Care Unit or withdrawn from the Intensive Care Unit to the service, and patients taking drugs or supportive treatment that could affect blood Folate, B12, Iron levels were excluded from the study. p<0.05 was accepted as statistical significance level. Results: 48.6% (68) of the cases were male, 51.4% (72) were female. The mean age (Mean±SD) of all cases was 67.3±15.8. No significant difference was observed between the case and control groups in terms of age, gender, presence of comorbid disease, prognosis, Folate and B12 levels. However, the iron level was significantly higher in the case group. Conclusion: As a result, Folic acid and B12 supplementation is needed in the majority of COVID-19 cases. Before supplementing with iron, the iron level should be checked.
