Abstract
Few works studied the levels of vitamins and minerals in Saudi Arabia among COVID-19 patients, especially in the region of Taif (high altitude). So, this work aims to study the serum vitamin D, vitamin B12, calcium, Phosphorous, Magnesium and hemoglobin levels in recovered patients
with COVID-19 and compare them to mortalities. The levels of a sample of 100 recovered patients and 93 mortalities were chosen from the Covid 19 patient records between March 2020 and February 2021 in King Faisal Hospital, Taif, Saudi Arabia. Vitamins and Minerals data were distilled for statistical
analysis. The results reported that vitamin D was the highest in recovered patients compared with coronavirus mortalities, whilst vitamin B12 was the highest in mortalities compared with recovered patients with coronavirus. Calcium, as well as hemoglobin, were relatively elevated in recovered
patients with coronavirus compared to mortalities with coronavirus. The results indicated that there is a significant difference between recovered patients and mortalities in age, Vitamin B12, Calcium, Phosphorous, Magnesium and hemoglobin. There is a significant positive correlation between
Age and Vitamin B12 and Phosphorous. There is a significant negative correlation between Age and Magnesium and Hemoglobin. On the other hand, there is a significant positive correlation between Vitamin D and Vitamin B12. Finally, there is a significant positive correlation between Calcium
and Phosphorous and between Calcium Hemoglobin. As a result, deficiency of vitamin D, calcium, phosphorus and hemoglobin levels may cause a failure in the immune system against COVID-19 and cause a quick transfer to severe disease.
