Clinical and diagnostic features of East Coast fever (Theileria parva) infection of cattle

East Coast fever is a tick-borne protozoal disease affecting cattle in a large part of East and Central Africa. Since the vector occurs over an even wider range there is considerable potential for the disease to spread to countries which are currently disease free. This article, describing the clinical and diagnostic features of East Coast fever, may remind authorities in these countries of the potential hazards posed by the disease.
