The COVID-19 (Coronavirus Disease 2019) outbreak has not yet ended and poses a persistent hazard to individuals, communities, and healthcare systems globally. Similar to numerous other diseases, the immune system of the patient is intricately associated with the advancement and mortality rates of COVID-19. In general, the immune system plays a crucial role in protecting the host against infections and neoplastic cells, and a well-balanced diet can enhance the immune system's ability to effectively defend against infectious agents. There have been suggestions that the administration of zinc supplements may decrease the occurrence of lower respiratory tract infections in children who are deficient in zinc. This study will thus examine the potential of zinc as a preventive and therapeutic agent, either on its own or in conjunction with other techniques, as zinc fulfills all the requirements outlined above. The study cohort was stratified into three distinct groups, namely critical care patients, service patients, and a healthy control group; a total of 24 COVID-19 patients in critical care, 27 ward-treated COVID-19 patients, and 26 healthy individuals. The groups exhibited a notable disparity in age distribution (p<0.001). A statistically significant difference was seen among the groups in relation to the survey results, presence of chronic disease, and length of hospital stay (p<0.001, p<0.001, and p=0.007, respectively). COVID-19 patients (n=51) exhibited markedly reduced zinc levels in comparison to a control group of healthy individuals (n=26). It was observed that the average zinc level in patients diagnosed with COVID-19 was 89 μg/dl (range: 43-123 μg/dl). In comparison, the median zinc level in individuals without COVID-19 was found to be 99.5 μg/dl (range: 79-125 μg/dl). A statistically significant difference was observed between the groups (p=0.023). The study revealed that a total of 13 individuals, accounting for 25.5% of the COVID-19 patients, exhibited a deficiency in zinc levels. The findings of our study ©Copyright LMS.
