Lymphocytic choriomeningitis virus infection following occupational ocular exposure.

A man in his mid-20s presented to the occupational health service following an ocular projection with a concentrated solution of lymphocytic choriomeningitis virus (LCMV clone-13). Subsequently, a regular clinical and biological follow-up was initiated. 7 days after exposure, the patient developed influenza-like symptoms. During the acute phase, specific RT-PCR testing of blood plasma was negative for LCMV. Symptomatic treatment was administered, and the symptoms resolved after a few days. The patient remained asymptomatic in the following weeks. Serological follow-up detected a seroconversion 6 weeks after exposure, indicating a recent infection. The occupational health service's protocol, comprising clinical monitoring and serological surveillance, facilitated the detection of seroconversion. This case underscores ocular mucosal exposure as a route of occupational LCMV transmission, which is often not considered. It served as an opportunity to review and enhance prevention measures and laboratory protocols within the biosafety level P2 facility.
