Anthrax meningoencephalitis generally presents with fever, headache, vomiting, and confusion or agitation, but there may also be symptoms related to the source of infection (eg, cutaneous, gastrointestinal, inhalational, or injectional). Hemorrhagic meningitis should raise strong suspicion of anthrax infection. Anthrax meningoencephalitis is usually rapidly fatal, with roughly two thirds of affected patients dying within 24 hours of presentation. Anthrax is considered the most likely biological warfare agent.
