What is an example of a fungal infection?

• A. Ringworm
• B. Head Lice
• C. Asthma
• D. Impetigo

Answer: (A)

Recognizing fungal infections means identifying conditions caused by fungi rather than by parasites or bacteria. Ringworm is a fungal infection because it’s caused by dermatophyte fungi that invade keratin in skin, hair, or nails (even though the name suggests a worm). It usually appears as a circular, scaly patch with a clearer center and can be contagious through skin contact or shared items.

Head lice are caused by parasitic insects that live on the scalp, not fungi. Asthma is a chronic inflammatory condition of the airways, not an infection. Impetigo is a bacterial skin infection typically due to Staphylococcus aureus or Streptococcus species, not fungi. Therefore, ringworm is the example of a fungal infection.
