A cluster of anthrax cases including meningitis.

We report a common-source outbreak of anthrax. The source of infection was the carcass of a cow. Three patients developed anthrax, which affects meninx, skin and larynx. The patient with meningitis died. In all, 20 people who contacted or ate the cooked meat of the dead cow were given prophylactic tetracycline and remained well. This small outbreak calls for the increased awareness of physicians to this clinical entity in locations in which anthrax is endemic and for health education.
