In the UK, biochemist Iain R. Hargreaves and medical doctor David Mantle have written that the initial immune system response to the Covid-19 virus and the subsequent resolution of the resulting inflammationInflammation is an immune system response to an injury to cells or tissues. It is the body’s attempt to defend against invaders such as bacteria andviruses and to mend the damage done by invaders. Typically, inflammation manifests itself in the form of fever and swelling, in the swarming of white blood cells and the release of cytokines to fight against... More may well be dependent upon nutritional status, including micronutrient status. Accordingly, they have investigated the relationship between the status of two micronutrients, Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical... More and seleniumSelenium (symbol Se, atomic number 34) is a trace element that is an essential nutrient and an essential component of some of the most important antioxidants in the body, in particular the selenoproteins glutathione peroxidase, thioredoxin reductase, and selenoprotein P. Selenium is involved in the optimal functioning of the immune system. Professor Alehagen has pointed out that there exists a...

More may be one aspect of an effective program to prevent and treat Covid-19 infections [Hargreaves & Mantle 2021]. The important thing in dealing with Covid-19 infections is to achieve and maintain a balance in the immune response against the virus without causing a cytokine storm as the cytokine storm is the cause of lung injury and respiratory distress in severe cases.
