Is acute laryngitis in children contagious? It depends on the pathogen causing the infection. If the infecting pathogen is contagious, then certainly it can be transmitted. If the infecting pathogen is not infectious, then of course it will not be contagious. Contagious examples include diphtheria, influenza virus, and Coxsackie virus, which can cause transmission, so it is important to isolate as much as possible. If it is a bacterial infection, it is generally not contagious.

Therefore, one cannot simply say whether acute laryngitis in children is contagious or not; it depends on what the infection source is for this particular case to determine whether it is contagious or not.
