A comparative study of serum Zn, Cu, Mg, Mn, Cr, and Fe levels and their association with the vulnerability of Iraqi COVID-19 patients.

Background: For the immune system to protect the body from infectious diseases such as COVID-19, it needs the ideal amount of vital trace elements. Trace element levels, especially, zinc (Zn), copper (Cu), magnesium (Mg), manganese (Mn), chromium (Cr), and iron (Fe) levels, may affect how sensitive an individual is to COVID-19 and other viruses. The current study evaluated the level of those trace elements during stays in the isolation center and investigated their association with vulnerability to COVID-19.
