In 1993 the now famous ''mystery illness'' swept through the American
Southwest, claiming its first Navajo victim on 14 May. Faced with an i
llness that kills seemingly healthy people of all ages in less than fo
rty-eight hours, national health regulating agencies turned to biomedi
cine, while the families of Navajo victims turned to their own history
for answers. I analyze several interrelated episodes in the Navajo or
al history to show how monsters are metaphors for disease, immorality,
and misconduct. The stories provide a cultural context for explaining
the mystery illness and demonstrate the power Navajo history possesse
s to help contemporary people cope with life.
