The corona virus has different types. Particularly Covid-19 virus, the virus with RNA, has a quadruple protein structure, uses angiotensinconverting enzyme 2 as receptor, infects the cells with this receptor and, besides causing cell dysfunction, provides the ground for further spread of the virus and its escape from the immune system. In addition, it causes disorder in presentation of antigen by the immune system cells. People’ s body reaction, after the virus enters the body, is different and related to demographic conditions in a way that the highest mortality rate is closely correlated with an increase in age, gender and history of underlying diseases such as diabetes, hypertension, cardiovascular diseases, chronic respiratory diseases and cancer or history of surgery though we should not forget that the youth and healthy individuals can also be inflected and inflicted by this virus (1, 2). One of the important points related to this virus is its speed of spreading and pathogenicity, which can be related to the changes made in the genome of this virus during the spread of the disease. Furthermore, the genome structure of the virus is subjected to mutation and recombination (3), which causes increased infection at frequent intervals via direct contact, respiratory droplets or probably fecal-oral transmission (1, 2). The basic symptoms of infliction by the virus include temperature, cough, and shortness of breath, but other symptoms such as diarrhea, eye injury, and muscle bruising and pain have been also reported. Considering the fact that no effective vaccines have been successfully produced in the world, the important point in fighting this disease is the consensual emphasis of the experts in the field of health on observing the health protocols to prevent the transmission and spread of the disease (2)....
