The purpose of this study is; to give information about the biological structure, metabolism and interaction of the Covid-19 agent virus with the defense system; to reveal the relationship between biochemical blood values and the defense system in Covid-19 cases and to update the data on preventing the damage that the virus may cause, in line with scientific developments. Relevant articles found by searching the keywords “SARS-CoV-2” and “Coronavirus” in Pubmed, Web of Science and Google Scholar databases and Google Search Engine were included in the study. This virus, called SARS-CoV-2, which originated in Vuhan, China and caused the disease called Covid-19, spread to almost all countries of the world and caused a high number of deaths in a very short time. Using the virus RNA, the infected cell begins to produce proteins that will keep the immune system at bay and help create new copies of the virus. For this reason, monitoring the disease and sharing information all over the world, epidemiological contact history, clinical features, biochemical tests in all blood and urine and other conditions are important evaluations for the treatments of the patient. It is imperative to follow the global situation and to make correct decisions according to the changes in epidemiology and to update the information of employees.
