Should I inform the school that he has it? Should he be wearing long sleeves (it's on his arms)(hot, makes his eczema itch so don't want to have to). I know about not sharing towels but he is in very close contact in a tiny house with his siblings-are they bound to catch it? Can I use hydrocortisone on the eczema when he has mollusca in the same place? Any home remedies that can be used on very sensitive skin?
