Croup – Symptoms and Causes

Fever

When the virus causing croup penetrates the body, it will activate the immune system. This is a natural mechanism to fight against foreign invaders. You might experience a mild fever when the body increases the temperature to kill the virus. The symptom can last for a few days up to one week. It can also reoccur on a regular basis until the cause is completely resolved. In most cases, fever is not a serious concern as it tends to improve after a few days with some simple home remedies. However, if the body temperature exceeds 103.5 degrees or more, it is important to seek medical attention to avoid dangerous complications. [2]
