Unfortunately, many medical staff in hospitals and referral centers became ill, and some died due to frequent encounters with patients and severe cases of the disease. In the meantime, the issue of the spread of nosocomial infections should never be overlooked, and it should be thought that all attention should be focused on coronavirus, as the interaction between the virus and other strains of nosocomial infections is completely unknown. These measures are especially important in intensive care units for the care of Covid-19 patients, because the spread of this infection in these wards is strongly and exponentially associated with high mortality due to the disease. The outbreak of Covid-19 disease affected almost every country in the world, leading to more than 44 million cases and 1.2 million deaths by the end of October 2020. Another important point is the application of special and intensive protocols in the referral centers of patients in such a way as not only to prevent the spread of infection from disease to another patient but also to minimize the chances of infection of care and treatment personnel.
