The situation varies depending on the cause. If it is acute laryngitis caused by an injury, it is not contagious. However, if it is caused by an infection, such as by the epidemic influenza virus, or by Bordetella pertussis causing acute laryngitis, these infectious diseases cause inflammation of the larynx and are contagious. Or in cases of general bacterial and viral infections, there can be cross-infection, but they are not contagious.

How to treat acute laryngitis in children

If acute laryngitis in children is caused by a viral infection, it generally involves symptomatic treatment. If there is a fever with a temperature exceeding 38.5 degrees Celsius, or if the child appears unwell, antipyretic treatment can be administered. For persistent coughing, appropriate cough suppressants can be used for relief. Additionally, for hoarseness and throat discomfort, nebulized inhalation can be applied as symptomatic treatment. If there is a bacterial infection, antibiotics are certainly necessary to control the condition. If the acute laryngitis is caused by an injury, local symptomatic treatment can be applied to reduce the damage, followed by waiting for recovery.

The symptoms of acute laryngitis in children

First and foremost, the most typical symptom is hoarseness of voice, with accompanying symptoms varying depending on the severity of the laryngitis, and symptoms differ. Generally, mild cases may present with cough or fever; a few children might also have gastrointestinal symptoms, such as vomiting and diarrhea. If there is laryngeal obstruction, some signs of hypoxia will appear, such as cyanosis, intermittent stridor, profuse sweating, the three-concavity sign, flaring of the nostrils, listlessness, and even some convulsive symptoms.

Does acute laryngitis in children recur?

Acute laryngitis in children can recur, similar to tonsillitis. Some children may have inherently lower immune function in the larynx, or a relative defect, which makes them prone to inflammation in the larynx whenever there is an upper respiratory infection. Therefore, we generally inform parents that if the child has a history of laryngitis, they should be aware of this condition in the future, especially of sudden respiratory difficulty at night and hoarseness. It is important to pay attention as laryngitis tends to worsen at night, and if it occurs, we recommend seeking medical attention promptly.

Does acute laryngitis in children require hospitalization?

Acute laryngitis in children is a common illness, and most cases do not require hospitalization. They can be managed in the outpatient clinic with oral medication and nebulization. However, if laryngeal obstruction occurs, especially at the second degree or higher, hospitalization is necessary. Laryngeal obstruction is considered a pediatric emergency, which can quickly worsen, leading to difficulty breathing. Some cases may even require intubation or a tracheotomy as emergency procedures. Delayed medical attention or hospitalization could potentially be life-threatening. Therefore, depending on the severity of the child's condition, hospitalization may be required.

Do children with acute laryngitis have a fever?

Acute laryngitis may occur with or without fever. For children, acute laryngitis is primarily a local symptom, but because children generally do not have robust immune function, local infections can easily lead to systemic symptoms. Among systemic symptoms, acute laryngitis frequently manifests as fever, typically presenting as either mild or high fever. It is relatively rare to see extremely high fever. Therefore, it is usually recommended that if the fever exceeds 38 degrees Celsius, or if the child appears lethargic during the fever, oral administration or rectal insertion of ibuprofen suppositories or acetaminophen suppositories can be effective treatments.
