Abstract

While studying aseptic meningitis in Salvador, Brazil, we diagnosed anicteric leptospirosis in 1.7% (5/295) of patients hospitalized for aseptic meningitis. Leptospirosis-associated meningitis patients had lower mean cerebrospinal fluid cell counts and protein than other-cause aseptic meningitis (p<0.05). Clinicians must consider leptospirosis-associated meningitis in appropriate clinical-epidemiologic contexts.

Keywords: Brazil; aseptic meningitis; case series; leptospiral meningitis; leptospirosis; meningitis/encephalitis; neuroleptospirosis; viral meningitis; viruses.
