Brief summary

The first version of this preprint article is registered on the 4th of May 2020 under the digital object identifier of:10.31219/osf.io/u56fc. COVID-19 infections virus spread worldwide and impact many countries with sever economical sequences. The effective antiviral medication or vaccination for the virus is unavailable until the present date and it takes months or years to discover the effective treatment or test the efficacy of the discovered treatment. Based on these facts, the human immune system against the virus may have an effective role to regulate the infection and reduce the mortality rate among the infected patients. This proposed research article aims to explore the available medication/ natural supplementation to boost the immunity system of the patients against COVID-19 infections and reduce the mortality rate among infected patients. Methods: a proposed clinical trial will be carried out to investigate the effect of the different treatment modalities on the human immune system against COVID-19 infection.

Detailed description

Natural supplementations have many reported effects on the human health ranged from immunity boosting to effective antiviral effect. Omeg-3 as an example affect the human health by many mechanisms e.g. Anti-oxidant, immunity boosting agent. Moreover, Omega-3 exerts an antiviral effect on Flu virus by inhibiting influenza virus replication 1. On the other hand, black seed supplementation exerts a chelation effect on sickle cell anemia patients and inhibits Human Heme Metabolism 2. Moreover, black seed exerts an antiviral effect on the replication of old coronavirus and the expression of (TRP-genes) family 3. In addition, Omega-3 regulates the human immunity against bacterial and viral infections 4. During the past years, many natural sources exerts an antimalarial effect with perfect reported results 5.
