Lower zinc levels in blood may up death risk in Covid patients

Researchers have found that having a lower level of zinc in the blood is associated with a poorer outcome in patients with Covid-19.

According to the research, increased intracellular zinc concentrations efficiently impair replication or reproduction of a number of viruses.

However, the effect of plasma zinc levels on SARS-COV-2 is not yet understood.

“Lower zinc levels at admission correlate with higher inflammation in the course of infection and poorer outcome,” said study author Roberto Güerri-Fernández, Hospital Del Mar, Spain.

“Plasma zinc levels at admission are associated with mortality in Covid-19 in our study,” Güerri-Fernández added.

The authors did a retrospective analysis of symptomatic admitted patients to a tertiary university hospital in Barcelona over the period from March 15, 2020 to April 30, 2020.
