We report a case of acquired lymphocytic choriomeningitis virus (LCMV) infection due to an accidental percutaneous inoculation of LCMV at work. The injured worker developed a flu-like syndrome, followed by pericarditis and meningoencephalitis. Seroconversion was confirmed by ELISA. The patient made a complete recovery. We review measures undertaken to prevent a similar event and propose a follow-up protocol in the event of accidental LCMV exposure.
