When a child is healthy, the fever he is suffering from may not easily indicate if there is anything serious. Mostly, the temperature level during a fever does not indicate the seriousness of his illness. A high fever can be a result of just an infection of a mild level. Sometimes the infection may be of high level but presence of fever can’t even be felt at all. This kind of fever may not hurt the child but can be the cause of him being distressed and also result in dehydration.
