Laryngitis is an inflammation of the larynx, characterized by symptoms such as hoarseness and cough, and can be classified into acute and chronic types. The condition is influenced by factors such as age, gender, seasonal incidence, and infectious or non-infectious causes, with medical management tailored to its etiology. Prevention strategies include avoiding respiratory infections, smoking cessation, and proper hydration, while nursing interventions focus on alleviating symptoms and supporting airway clearance.
