laryngitis causes
Most acute cases of laryngitis are caused by viral infections, the most common of which tend to be rhinovirus, influenza virus, parainfluenza virus, adenovirus, coronavirus, and RSV. In patients who have a compromised immune system, other viruses such as herpes, HIV and coxsackievirus may also be potential causes.
Acute laryngitis is most commonly caused by a viral infection, such as a cold or flu. Another type of acute laryngitis is mechanical laryngitis. This can be caused by: Overusing or misusing your voice. Excessive, singing, speaking or shouting. Persistent coughing and throat clearing. A throat injury.
Laryngitis is an inflammation of the vocal cords. Most commonly, acute laryngitis is caused by an infection that inflames the vocal cords. In infants and young children, the classic signs and symptoms of an inflamed larynx include: Croup. A hoarse barky cough.
