The medical abbreviation "URI" stands for "Upper Respiratory Infection". An upper respiratory infection is a common viral infection that affects the nose, throat, and sinuses. Symptoms of an URI can include nasal congestion, runny nose, sore throat, cough, fever, and headache. It is usually a self-limiting illness and can resolve on its own without treatment, but in some cases, medical intervention may be necessary to relieve symptoms or to prevent complications.
Healthcare professionals may use the abbreviation URI in medical records or when discussing a patient's medical history or symptoms.
