Is laryngitis contagious?

Laryngitis is only contagious if it is caused by an infection. Laryngitis, upper respiratory infections, and colds are commonly a contagious viral infection spread by aerosol droplets.

Disease transmission can be minimized or prevented by covering the nose and mouth when coughing and sneezing, and proper hygiene habits (wash your hands often, don't share food utensils, and wipe down door handles).

How does laryngitis last?

Laryngitis is self-limiting and should last for only a few days, and symptoms should resolve within 7 days, but can linger up to two weeks. If symptoms persist longer than three weeks, this is considered chronic laryngitis and causes other than a viral infection need to be explored. Croup is often described as a disease of the nighttime because visits to the emergency department peak after midnight with sick infants and children.
