As I told you previously it is very difficult to diagnose a child's skin rash without being able to see the rash.Scabies is certainly a very itchy rash, but it does not need to spread very much once the rash is established.If he is allergic to milk it will not matter if the milk is pasteurised or unpasteurised.
