Heavy Metals Explain the Relation between Toxoplasma gondii, Influenza virus and COVID.19

Abstract

Heavy metals such as zinc responsible for many biological tasks in human body, and these functions disturb upon alteration of these essential metals, beside these positive roles, metals also induce many pathological problems. In this article we suggest the role of toxoplasma gondii as host for influenza virus that provide suitable environment to the virus to evade immune system. And according to hypothesis mentioned that; COVID.19 is mutant form of influenza virus, we said that slow spread of the pandemic among population with high prevalence of toxoplasmosis attributed to role of zinc in regulation of immunity, through protection of host cells from the virus and protection of parasites that hold viral colonies and prevent it spreads. Further studies recommended to check these hypothesizes.
