Eczema in sub-Saharan Africa

Introduction

Eczema, also known as atopic dermatitis, is a common skin condition that causes dry, itchy, and inflamed patches on the skin. This can affect both adults and children, with children from Africa often showing different eczema patterns compared to children of other ethnicities. It is not contagious but can cause significant discomfort, particularly due to the intense itching that can affect sleep, especially in children.

Discussion
Eczema in Children

Children with eczema may experience dry, red, sore, and itchy patches on their skin. The itch can be unbearable, often leading to constant scratching, which can further irritate the skin, especially at night. In moderate to severe cases, children may scratch until their skin bleeds, and the dry areas may crack, exposing the skin to infections. African children just other children in the world often develop eczema in the creases of the knees and elbows, with fine bumps sometimes appearing on the chest and tummy.

  • Small bumps that break and bleed when scratched
  • Blisters, oozing, and crusting (indicating infection)
  • Rash that varies in color based on skin tone

  • Darkening of skin around the eyes
Causes of Eczema

Eczema may result from a combination of genetic factors and environmental triggers. Some causes include:

  • Genetics: Family history of eczema, asthma, hay fever, or allergies can increase the risk.
  • Skin Barrier Defects: A gene variation can weaken the skin’s ability to retain moisture and block harmful substances.
  • Environmental Irritants: Exposure to smoke, air pollution, harsh soaps, certain fabrics (like wool), and allergens like pet dander or pollen.
  • Climate: Hot and humid conditions can worsen symptoms, likewise during harmattan or dry season, there may be more of the symptoms.
  • Emotional Stress: Anxiety, stress, or depression can trigger eczema flare-ups.
