Abstract: With the spread of novel coronavirus pneumonia (NCP), the routine treatment of cancer patients has been affected. Oral cancer is one of the malignant tumors which needs timely treatment. Due to the particularity of its location, it is more difficult to differentiate with NCP if fever occurs during the stay in hospital. Therefore, it is particularly important to evaluate the risk of NCP infection in oral cancer patients with fever symptoms during the hospital stay, identify the differential diagnosis criteria, and make corresponding prevention and treatment measures.

Key words: novel coronavirus pneumonia (NCP), oral cancer, inpatient, fever
