There are many causes of red spots on the palms of babies: 1. Eczema caused by allergic skin diseases is common. The child is prone to low fever, anorexia, oral pain and other manifestations, and herpes, pimples or ulcers are also likely to appear on the hands, feet and mouth area; 3. Ringworm is mainly caused by red trichophyton infection, resulting in red patches or red dots on the palm area, dry, cracked, blistered or eroded skin and other manifestations; 4. If the baby is often exposed to detergents or allergens, it can lead to skin allergy on the hands, which can cause red dots on the palm area. At this time, you should avoid your baby from eating spicy, stimulating or seafood food, otherwise it will lead to aggravation of the symptoms.
