Pediatric laryngitis is not necessarily contagious, depending on what pathogen is infected. If it is usually a bacterial infection, it is generally not contagious, if it is a viral infection of the respiratory tract, then there is a possibility of infection through droplets, or the need for isolation treatment. Pediatric laryngitis is usually characterized by sore throat, hoarseness, and in severe cases, fever. It is usually checked for respiratory viruses, and if the test is positive for respiratory viruses, it may be a viral infection that requires more attention and isolation.
