What causes laryngitis? and how to avoid it in future. i lost my voice for 2 weeks. so i want to know how to prevent it

Respiratory viruses: That means preventing laryngitis (or croup in young children) is like preventing the common cold. People in one household tend to get the same upper respiratory infections at the same time, because the germs (usually viruses) are contagious. In the fall season, we see kids getting croup (cold symptoms and a barky cough). The same viruses that cause croup can cause laryngitis in teens and adults.
