Eczema in infants and young children, if there are no obvious other accompanying symptoms, usually do not need to do anything related to the examination. If the eczema is accompanied by infection, such as redness and swelling of the eczema area or flaking of the eczema area, relevant tests are needed. If the redness and swelling are more pronounced, it is usually necessary to check blood tests or even allergens. If the eczema is accompanied by dryness around the eczema and some degree of flaking, the possibility of fungal infection should be suspected and a fungal test may be needed. Fungal testing involves taking scales from the baby’s skin, sending them to a lab, and examining them microscopically through a microscope to determine if there is a fungal infection.
