Increasing intracellular Zn concentration via zinc ionophores can efficiently impair intracellular replication of a variety of RNA viruses, including poliovirus, influenza virus and COVID-19-causing SARS-CoV-2 coronavirus, as demonstrated with such zinc ionophores as pyrrolidine.

Zinc in combination with a zinc ionophore (which helps zinc enter human cells) can inhibit viral replication in human cells. It is also available as a dietary supplement. ZINC is an essential mineral present in many foods.
