You can differentiate whether it is a viral infection or bacterial infection based on the color of the secretion, blood test, throat examination and other ways. 1. Color of secretion: If you cough up phlegm and have a runny nose, the color of secretion is yellow. Yellow secretion is purulent phlegm, which is a sign of bacterial infection. 2. Routine blood test: If the leukocyte index is increased in routine blood test, and the increase of neutrophils is dominant, it is bacterial infection, and the total number of leukocytes is normal or low, and the percentage of lymphocytes is increased, it is viral infection. 3. Pharyngeal examination: the pharynx is obviously congested, and the tonsils are enlarged, with purulent secretion, accompanied by yellow pus spots, which proves that it is a bacterial infection; if it manifests sore throat, fever, pain in swallowing, and the mucous membrane of the laryngeal wall has white or red papules, which proves that it is a viral infection.
