Laryngitis- Causes, signs and symptoms, treatment and prevention


Laryngitis refers to the swelling or inflammation of your larynx (voice box) from irritation, overuse, or infection. The vocal cords which produce sound are inside the voice box or larynx. The larynx consists of two mucous membrane folds that cover cartilage and muscle. Normally, the vocal cords should open and close, which means they vibrate without problems, forming sounds through their vibration and movement. 

However, due to the condition known as laryngitis, they become irritated and often become inflamed, distorting the voice produced due to the air passing over them. As per this condition, it results in hoarseness of the voice. Sometimes the voice becomes totally undetectable. This triggers the question in your mind- “is laryngitis contagious?”
