National Eosinophil Awareness Week (May 15-21, 2022) Recognizes Impact of Eosinophil-associated Diseases

May 13, 2022

Atlanta, GA (May 13, 2022) – The American Partnership for Eosinophilic Disorders (APFED) will celebrate the 15th annual National Eosinophil Awareness Week (NEAW) from May 15-21, 2022. APFED is engaging people across the world to raise awareness of eosinophil-associated disorders.

Eosinophils (pronounced “ee-oh-sin-oh-fills”) are a type of white blood cell that is formed in the blood marrow. They are part of the immune system and help with infections, inflammation, and allergies. If a person has too many eosinophils, without a known cause, they may have an eosinophil-associated disease.

Many patients experience a delayed diagnosis of eosinophil-associated diseases. The diagnosis depends on where in the body the eosinophils are found. Eosinophils may affect different parts of the body, including but not limited to the gastrointestinal tract, heart, sinuses, blood, lungs, bladder, and connective tissue.

Eosinophil-associated diseases are rare. They are chronic conditions that require long-term management. They can also be debilitating and impact quality of life. The conditions affect both adults and children.

In 2007, the U.S. House of Representatives passed House Bill 296, an initiative spearheaded by APFED, to officially recognize the third week of May as NEAW. Since then, advocates have increased efforts during this special week to shine a public light on eosinophil-associated diseases and the impacts of living with them.

“Although we work year-round to educate, National Eosinophil Awareness Week is a dedicated time to increase efforts to teach the public and medical communities about symptoms, diagnostics, and treatments. When symptoms are recognized more quickly, the diagnostic timeline decreases, and patients can start treatment sooner,” said Mary Jo Strobel, APFED’s Executive Director. “We are calling on everyone to join our community’s efforts to educate, and to learn about these conditions and their impacts.”

Buildings and landmarks around the world are lighting up magenta in honor of National Eosinophil Awareness Week. A list of locations that will light up is available at

This includes Abbott, Allakos, Arena Pharmaceuticals, AstraZeneca, Bristol Myers SquibbTM, Ellodi Pharmaceuticals, GlaxoSmithKline, Nutricia, Sanofi, and Regeneron.
