In addition to infections with Staphylococcus aureus and rarely with Herpes simplex (the cold sore virus), children with atopic eczema are also susceptible to common warts and molluscum contagiosum. Molluscum ontagiosum are seen as numerous small white bumps that persist for up to 6 months to a year, and sometimes even longer. They eventually do disappear, with or without treatment.
Children with eczema are also prone to have food allergies causing either anaphylaxis in some cases or more subtle reactions that worsen the eczema. Allergies to environmental factors such as animal dander and dust mite can also worsen eczema in some children. Many children with atopic eczema go on to have inhalant allergy to airborne substances such as pollens and mold spores in addition to animal dander and dust mite that results in allergic rhinitis, conjunctivitis, and asthma.
