Final answer:
Eosinophilia can be caused by asthma, prolonged infection, and atopic dermatitis (eczema).
Step-by-step explanation:
Eosinophilia is a condition characterized by an elevated number of eosinophils, a type of white blood cell, in the blood. Several conditions can cause eosinophilia, including:
- Asthma: Asthma is a chronic respiratory condition characterized by airway inflammation and bronchial hyperresponsiveness. It can lead to eosinophilia as a result of the immune response.
- Prolonged infection: Certain chronic infections, such as parasite infections, can trigger eosinophilia as an immune response to the infection.
- Atopic dermatitis: Atopic dermatitis, also known as eczema, is a common inflammatory skin condition that can cause eosinophilia.
