Eosinophils are a type of white blood cell that play an important role in our immune system, especially in defending against certain infections. However, when too many eosinophils are present without a known cause, it may be the result of an eosinophil-associated disease.

May 18-24, 2025 marks the 18th annual National Eosinophil Awareness Week (NEAW) — an opportunity to raise awareness, foster community, and spark conversations about these diseases, many of which are rare.  During this special week, we will also celebrate World Eosinophilic Diseases Day (May 18) and World EoE Day (May 22).

Whether you’re personally affected or supporting someone who is, there are many ways to get involved. Here are ideas built around our E.D.U.C.A.T.E. theme:

E – Educate

Learn about eosinophil-associated diseases and share infographics on social media with hashtags #NEAW and #EosAware.

D – Donate

Encourage your friends and family to contribute to eosinophil disease research.
Host an online or in-person fundraiser to support APFED’s mission.
Participate in the 2nd Annual Walk for Hope by walking, running, biking, or hiking. It’s easy to get involved—create a team to rally friends and family, or simply join Team APFED.

U – Unite

Register for EOS Connection 2025, APFED’s annual patient education conference. It’s hybrid again this year — join us in Raleigh-Durham, NC, or virtually, on June 26-28, and again on July 16-18 for our virtual research roundup.
