The video shows a child with hives. Hives is a rash triggered by allergies, and it is very itchy and moves around the body.
This infant has hives or urticaria. She has an itchy rash all over her body, consisting of large and small, raised red welts. While hives usually come in the form of raised red welts, they can also be circular with white centers. The rash can move around the body and will usually last for 3 to 4 days before disappearing. Hives are most often caused by an allergic reaction. They are generally not dangerous and can go away on their own without any medical treatment. However, contact the doctor or call 911 immediately if the rash appears on the mouth or throat, or if it's causing your child to have difficulty breathing or swallowing, or if it is part of a more pronounced allergic reaction.
