Croup is a respiratory illness that mainly affects children and is characterized by a distinctive barking cough. It is caused by inflammation of the larynx, trachea, and bronchial tubes, which can result in narrowing of the airways and difficulty breathing. The most common cause of croup is a viral infection, such as the parainfluenza virus.
Symptoms of croup include a barking cough, a hoarse voice, a high-pitched noise when breathing in, and difficulty breathing. In severe cases, children with croup may also experience stridor (a loud, high-pitched breathing sound), retractions (the skin between the ribs and above the collarbone pulls in with each breath), and wheezing. Croup is usually mild and goes away on its own within a few days, but in some cases, it may require medical treatment such as a corticosteroid or a cool mist from a humidifier. If a child is having difficulty breathing or is struggling to get enough air, it is important to seek medical attention immediately.
