What is the first line treatment for mild viral croup?

The first-line treatment for mild viral croup is the use of humidified air and observation. This approach takes advantage of the fact that many cases of mild croup, which is often caused by common viral infections, resolve on their own without the need for more aggressive interventions.

Humidified air helps moisten the airways and can alleviate some of the upper airway obstruction and associated symptoms like stridor and a barking cough. By providing a more comfortable environment, it supports symptom relief in children with mild symptoms. Observation is also crucial, as it allows healthcare providers to monitor the patient for any signs of deterioration or progression to more severe croup requiring further treatment.

In more severe cases of croup, other treatments such as oral steroids may become necessary, but in mild cases, simple interventions like humidified air are effective and appropriate. This is why this option is considered the correct approach for managing mild viral croup.
