More severe and debilitating forms of HPV infection cause lesions in the upper respiratory tract. These lesions can occur on any part of the respiratory tract, including the nose, mouth, and lungs. The most common site is the larynx or vocal cords. When HPV infects the vocal cords, hoarseness is a common symptom. If it affects other parts of the respiratory tract, it can cause difficulty breathing. It is important to seek proper medical treatment to prevent the condition from worsening over time.
