Clinical significance summary: Preliminary results of a rapid review of zinc for the prevention and treatment of SARS-CoV-2 and other acute viral respiratory infections

Abstract

As of 9 June 2020, indirect evidence from other types of viral respiratory infections suggests that zinc may potentially reduce the risk, duration and severity of SARS-CoV-2 infections; particularly for populations at risk of zinc deficiency. Notably, people with chronic disease co-morbidities and older adults are at risk of lower zinc status. Pending the results of SARS-CoV-2 clinical trials, clinicians might consider assessing zinc status as part of a SARS-CoV-2 clinical work-up to determine if short-term zinc supplementation, either orally or intravenously is indicated for those with low or borderline low results, low dietary intake and/or increased needs.
