• Answer:

  He might have caught one of the childhood diseases, such as chicken pox. These illnesses are usually self limiting and don't cause any problems, but if you are concerned, take him to a doctor. These are the signs of chicken pox: Initial symptoms of chicken pox include fatigue, a mild fever, lack of appetite and a feeling of being generally unwell. This is quickly followed (within 24 hours) by the development of a red rash. The rash usually appears on the chest and/or back first, later spreading to the face, scalp, arms and legs. Twelve to 48 hours later the rash develops into small red spots. These then turn into yellow blisters, which burst and dry up 3 - 4 days after they appear. There may be several crops of spots occurring over 4 - 5 days. The spots cause itching, which may be severe. They may occur all over the body including the mouth and genital area. Some people may have only a few spots whereas others will have hundreds. Full recovery from chicken pox usually takes 7 - 10 days after the symptoms first appear.
