The most typical symptoms of acute laryngitis in children are hoarseness, fever, and difficulty in breathing. During laryngitis, due to edema in the pharynx and epiglottis, the passage of air during speech becomes narrow. The movement of the vocal cords is not as normal as usual, and hoarseness may be noticeable. In more severe cases of laryngitis, sudden loss of voice and inability to speak may result. The onset of laryngitis is mainly caused by infection with bacterial and viral pathogens. These pathogens release large amounts of pyrogen when they attack the body, causing fever. The temperature of the fever varies, depending on the child’s immune response. When the body temperature is high, necessary cooling measures are needed. As the body fights bacteria and viruses, it releases chemicals that cause pain and the child may feel painful discomfort in the throat. The throat is the channel through which a person breathes normally. During illness, the larynx can become edematous in varying degrees of severity due to inflammation. This edema, if more severe, can cause the passage for air to enter to become narrowed or even blocked. Therefore, children will feel a struggle to breathe air. In exceptional cases, complete obstruction due to laryngeal edema can even cause asphyxia. This is the most serious form of laryngitis and must be taken seriously. The symptoms of laryngitis are mainly caused by pathogens and the temporary loss of the normal anatomical shape of the larynx. Parents must be observant when caring for their children. It is important to detect any discomfort in the child’s body and provide timely treatment.
