Welcome to the IDF Zebra Zone…a special place for children to show their stripes and THINK ZEBRA!


Why does the Immune Deficiency Foundation say, “THINK ZEBRA!”?
When doctors go to school, they learn the saying, “When you hear hoof beats, think horses, not zebras.” This means, when doctors treat people they should think about common illnesses, not unusual ones. However, sometimes people get sick a lot, their illness doesn’t get better or they have an unusual infection. When this happens, doctors should wonder whether the person might be a zebra with an unusual condition, like primary immunodeficiency disease, and not a horse with a common infection. People with primary immunodeficiency diseases are the zebras of the medical world! Help IDF teach everyone to THINK ZEBRA! “When you hear hoof beats, think zebras, not horses.”
