Tom was funny, kind, and full of life. He passed away in March 2025, aged 21, after glandular fever became something none of his family had ever heard of, EBV-HLH. This foundation is his legacy — and our promise to make sure others don't face what he did without warning.

Nobody knew what EBV-HLH was. Nobody had heard of it. That's the problem — and it's exactly what this foundation is here to change.
Understanding the condition
What is HLH (Hemophagocytic Lymphohistiocytosis)?
HLH Hemophagocytic Lymphohistiocytosis is a rare, life threatening, immune system disorder, where specific white blood cells become overactive and attack the bodies own tissues and organs. It is a severe imflammatory response, causing multi-organ failure, and requiring urgent medical care.
What is EBV-HLH specifically?
EBV-HLH is HLH triggered specifically by the Epstein-Barr virus — the virus that causes glandular fever. This is the form of HLH that Tom had. EBV is an extremely common virus; most people who contract it recover from glandular fever without lasting harm. In a small number of cases, however, the immune response to EBV does not stand down. Instead it escalates into HLH — and when it does, it can be catastrophic.

In the early stages, EBV-HLH looks like glandular fever — fatigue, fever, swollen glands. By the time the immune reaction escalates, it can move extremely fast. Without prompt recognition and treatment, it is frequently fatal.
Why does research matter so much?
To move forward with any disease you need Research. Claire Shannon-Lowe is working worldwide with Researchers on EBV-HLH. We also need funding to raise awareness to the NHS.

WHAT WE STAND FOR
We raise money for Researchers working specifically on EBV-HLH. Prof. Claire Shannon-Lowe at University of Birmingham. Every penny we raise goes directly to them.
Most people have never heard of EBV-HLH. Most GPs have never seen a case. We want that to change — because earlier recognition means earlier treatment, and earlier treatment saves lives.
EBV-HLH is most often fatal. If you have lost someone to it, we want you to know you are not alone. We are building a community of families who understand this particular grief — because very few people outside it will.
We're a family raising funds for two research teams working on EBV-HLH right now. No admin fees. Everything you give goes directly to the science.
We are a fundraising charity, not a clinical service. Nothing here constitutes medical advice. In an emergency, call 999.
