For the general public, if they are not hospitalized and do not come into contact with febrile patients, goggles are usually not required and a mask is sufficient for protection. However, goggles are required for protection in areas such as isolation wards (rooms), isolation wards (rooms) and isolation intensive care wards (rooms), and for medical workers who perform operations such as collection of respiratory specimens, tracheal intubation, tracheotomy, non-invasive ventilation, and aspiration. In addition, other areas and in other areas of the diagnosis and treatment operations, in principle, can temporarily do not use goggles.
