What is the chief complaint associated with an upper respiratory infection (URI)?

The chief complaint associated with an upper respiratory infection (URI) is typically cough and congestion. This is because URIs primarily affect the nasal passages, throat, and sinus cavities, leading to inflammation, increased mucus production, and blockage of the airways. As a result, individuals often experience a persistent cough due to irritation and the need to clear mucus from the respiratory tract. Congestion is also prevalent as it reflects the swelling of the mucous membranes in the upper respiratory tract, making it difficult for air to flow freely and contributing to the sensation of stuffiness or pressure.

While sore throat, fever, and myalgias can certainly accompany a URI, they are not the hallmark symptoms. Sore throats may occur due to throat irritation or infection, fever might arise as a systemic response to infection, and myalgias can be present as part of a viral illness response. However, cough and congestion are the most defining symptoms that patients commonly report, making them the chief complaint in cases of upper respiratory infections.
