How is eczema transferable? Any ways to deal with it?

Protect. Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
It isn't. Eczema is not contagious. And there are many ways to treat it, depending on what kind it is, how severe it is, and other factors.
