It is marked by cough, dyspnea, anorexia and constipation.
Therefore, manual diagnosis is done at many levels. Diagnosis basically relies on a combination of postmortem analyses, clinical signs displayed by the animals, and response to drenching . In heavy infection, symptoms are easily observed in sheep and cattle as they become severely anorexic or inefficiently digest food, and become unthrifty.

A more acute form of East Coast fever called corridor disease occurs when buffalo-derived T. parva is transmitted to cattle. [3] Another form, called January disease, only occurs over the winter months in Zimbabwe due to the tick lifecycle. [citation needed] Native cattle are often resistant to the parasite, but not without symptoms. They are ...
