What Is Croup?

5. How Long Does Croup Last?
Uncomplicated cases of croup typically resolve in less time than the virus that causes the symptoms. During the day, symptoms are usually milder and can seem to be resolving. At night, symptoms tend to worsen, but since this is a typical pattern of symptom fluctuation, it does not mean the condition is worsening.
When a child cries or gets upset, the symptoms can also seem to worsen, but this does not mean the condition is getting worse. Although the cold may last for a week or more, croup is usually shorter-term and will resolve within three to five days. Some cases do get worse with time, so the child should be evaluated by the doctor if symptoms are worsening or have lasted longer than five days.
