Coronavirus is a respiratory disease, and in our country, novel coronavirus pneumonia is a category B disease, but is managed as a category A disease. Transmission is mainly through respiratory droplets and contact, but aerosol and digestive tract transmission have been reported, but these two routes of transmission are not yet known. For the general population, to prevent coronavirus infection, we should wear a mask when we go out and not go to densely populated and confined places to prevent respiratory droplet transmission. Wash your hands promptly after touching public objects, avoid touching your nose or eyes with your hands, and open more windows for ventilation inside your home.
