Boils contain bacteria within the pus.
Children having frequent boils often carry the bacteria in their noses. Close playmates may be carriers. Keep your child's nails cut short, and hands washed often. Try to keep your child from putting his fingers in the nose. Use an antibacterial soap to help prevent boils.
