This is going to sound silly, but there is a grain of truth to it; Marburg needs a scarier name before Americans pay much attention to it. The word or surname Marburg sounds serene and comforting, like a silouette of The Marlboro Man on a horse. The disease; not so much. We need something with a sharp vowel sound or with a strong almost deliberate dissonance to it. Lyme disease is quick and punchy, The Flu, has a long U, Diarrhea has the long E-E, Tapeworm has the long A, plus it paints a picture.
