J06.9: Acute upper respiratory infection, unspecified
Your upper respiratory tract is inflamed.
The respiratory tract guides air into the lungs. The upper respiratory tract begins in the mouth and nose. The sinuses are also part of the upper respiratory tract. The sinuses are connected to the nose via a small opening. The throat is located behind the mouth and nose. The throat connects the mouth and nose with the windpipe (trachea) and gullet (oesophagus). The larynx is located at the junction between the throat and windpipe. The larynx can be seen from the front as a bulge in the neck. The upper respiratory tract ends at the larynx.
An inflammation in the upper respiratory tract can cause various symptoms. You may have sniffling, coughing or a sore throat. You may also be hoarse.
