Vocal Issues Due to Infections
Common infections that affect the voice include:
- Sinusitis – infection of the sinuses can cause post nasal drip and mucous, which drips onto the vocal cords and dampens their vibration.
- Tonsillitis – infection of the tonsils can cause a severe sore throat, airway obstruction and vocal fatigue.
- Laryngitis – infection of the vocal cords themselves can cause hoarseness due to swelling and excess mucous.
- Bronchitis – infection of the lungs can cause a cough that irritates the vocal cords.
- Oral or systemic yeast – more of an overgrowth than a true infection, yeast causes a thick mucous covering over the vocal cords and swelling.
