Patients with NE were monitored for parallel infection of LCMV, LV and OPV.
We evaluated if these infections were associated with atypical symptoms in patients.
A number of LCMV and LV, and one OPV seroconversion/s were detected.
No clinical findings were associated with LV or OPV seroconversions.
We provide the first report of LCMV seroprevalence in Finland.
