What type of infection is croup classified as?

Croup is classified as a viral infection, primarily caused by viruses such as the parainfluenza virus. This condition typically affects young children, leading to a distinctive bark-like cough, hoarseness, and difficulty breathing due to inflammation in the upper airways. Key characteristics of croup include that it often follows a viral upper respiratory infection, which highlights its viral etiology. Recognizing croup as a viral infection is important for treatment approaches, as antibiotics would not be effective in treating viral infections, but supportive care and management of symptoms are essential. Understanding this classification helps in anticipating and addressing the potential severity of symptoms, especially during the nighttime when symptoms may worsen.
