What can be done to prevent the condition?

Most causes of laryngitis are preventable. The majority of cases in young people are caused by overuse of the voice or infection. Avoiding exposure to sick people and avoiding overuse of the voice would prevent most of these cases. In older people, smoking and cancer are additional causes. Smoking can cause laryngitis directly. Smoking and alcohol use are both risk factors for cancer of the larynx. Treatment of severe gastroesophageal reflux with medications can also help prevent laryngitis.

What are the long-term effects of the condition?

If the underlying cause is corrected, there are usually few or no long-term effects. Cancer of the larynx may result in death if the cancer spreads.

What are the risks to others?

There are generally no risks to others. Infectious causes of laryngitis may be contagious.
