The video shows a boy with a temperature of 40ºC. He is playing and seems to be fine. This is an example of a child that can have a high temperature and still appear to be generally well.
Although this 1-1/2-year-old boy has a fever of 103 degrees, he is alert, plays eagerly, and interacts well with his surroundings. His mother reports that his appetite is good and his activity level is about the same as when he is healthy. These are all signs of handling his illness with fever well.
