Infections like folliculitis or impetigo are other potential causes. Folliculitis occurs when hair follicles become inflamed, often due to bacterial or fungal infections, resulting in pustules that crust over. Impetigo, a highly contagious bacterial infection, is particularly common in children but can affect adults as well. It’s characterized by red sores that quickly rupture, ooze for a few days, and then form a yellow-brown crust.
3. Impetigo: A Common Culprit
Impetigo is a skin infection caused by either Staphylococcus aureus or Streptococcus pyogenes bacteria. It typically begins as red sores or blisters that eventually burst, leaving behind a thick, golden-yellow crust. This condition is particularly common in warm, humid environments and spreads easily through close contact.
While impetigo is more prevalent in children, adults are also susceptible, particularly those with cuts or abrasions on the skin, which provide an entry point for bacteria. Early identification and treatment are crucial to prevent the infection from spreading to other areas or individuals.
