Laryngitis, there is acute laryngitis and there is chronic laryngitis. Acute laryngitis, an acute catarrhal inflammation of the laryngeal mucosa; chronic laryngitis, a chronic nonspecific inflammation of the larynx. Acute laryngitis is somewhat contagious in its early stages. Acute laryngitis, which often follows an upper respiratory tract infection, is first a viral infection and is somewhat contagious; when followed by a bacterial infection, it is essentially no longer contagious. In acute laryngitis, hoarseness may occur after cold symptoms such as nasal blockage, clear or mucous nasal discharge and pain in the throat. Hoarseness is the main symptom of acute laryngitis, which occurs due to inflammation causing congestion and swelling of the vocal cords resulting in reduced elasticity of the vocal cords. Chronic laryngitis, on the other hand, is caused by excessive use of the voice in general, too much; or long-term inhalation to harmful gases or dust; or repeated attacks of acute laryngitis; as well as the stimulation of chronic inflammation of the upper and lower respiratory tracts or the spread of chronic inflammation of the mucous membrane. If there is gastroesophageal reflux disease, it can also irritate the mucosa of the larynx and cause chronic laryngitis to occur. Chronic laryngitis is not contagious if it is not caused by tuberculosis of the lungs. Since acute laryngitis is somewhat contagious in its early stages, proper isolation is required. It is important to improve poor diet and lifestyle habits, not to eat spicy and irritating foods, and to stop smoking and drinking. Have a good and scientific habit of using the voice. Actively treat chronic diseases of the organs surrounding the larynx.
