(8) A rodent reservoir in the indigenous cotton rat, Sigmodon hispidus, was suspected and established initially by a 13% seroprevalence of antihantaviral IgG antibodies in trapped cotton rats; it was later confirmed by the detection of BCC virus RNA in seropositive rats by reverse transcriptasepolymerase chain reaction (RT-PCR) assay.
