Step-by-step explanation:
Croup is a respiratory infection that is characterized by a hoarse voice and a barky cough. It is caused by inflammation and swelling of the airways, particularly the larynx and trachea. It commonly affects young children, usually between 6 months and 3 years of age.
During croup, the child's voice may sound hoarse, and their cough may be harsh and barking, resembling the sound of a seal. Other symptoms may include shortness of breath, wheezing or a high-pitched sound during inhalation, and stridor - a harsh vibrating noise when breathing in. Additionally, the child may experience a low-grade fever, sore throat, and discomfort with swallowing.
Croup is usually caused by a viral infection, such as the parainfluenza virus. It typically lasts for 5-6 days and can be managed with supportive care, including plenty of fluids, rest, and humidified air.
