What Is an Upper Respiratory Infection?
5. What Are the Symptoms of a URI?
Your body’s immune response along with the toxins that pathogens release lead to the symptoms you experience with a URI. Symptoms can vary in severity and type. People with upper respiratory infections frequently experience nasal congestion and runny noses, sneezing, sore throat, coughing and sometimes a low-grade fever.
On occasion, other symptoms are also displayed, including loss of smell, bad breath, nausea, vomiting and headaches. URI symptoms typically last no more than 14 days. If they continue beyond that time, it is important to see your doctor.
