Additionally, the percentage of patients with a NLR greater than 4, elevated CRP, and fibrinogen levels was higher in the zinc-deficient group (<i>p</i> = 0.0017, <i>p</i> = 0.0107, <i>p</i> = 0.0338, respectively).<h4>Conclusion</h4>Zinc deficiency was observed in 28.6% of children with COVID-19 and was not dependent on age. This evidence concerns the gene CRP and Zinc deficiency.
