IMMUNOLOGY

Detailed explanation-1: -Eosinophils are one of several white blood cells that support your immune system. They’re part of your body’s defense system against allergens and help protect your body from fungal and parasitic infections. Certain medical conditions and medications can cause high eosinophil counts.

Detailed explanation-2: -The most common parasitic infections associated with eosinophilia in refugees are the soil-transmitted helminths (trichuris, ascaris and hookworm), strongyloides, and schistosoma as well as many tissue-invasive parasites (e.g. parasites that migrate through human tissues as a part of their life cycle).

Detailed explanation-3: -However, the number of circulating eosinophils are increased in patients with allergic diseases and helminth infections. Eosinophil granules contain major basic protein, eosinophil cationic protein, eosinophilic peroxidase and eosinophil-derived neurotoxin.
