Sin Nombre, Bloodland Lake, and Blue River are three strains of Hantavirus responsible for human Hantavirus Pulmonary Syndrome (HPS) that are associated with common Missouri rodents. HPS, which is 38% fatal, results from rodent bites or exposure to aerosolized urine/feces and has been documented in all of Missouri’s border-states except Arkansas (www.cdc.gov). To address a lack of knowledge regarding rodent seroprevalence, five locales, representing 6 habitat types, were sampled within Adair, Chariton, and Schuyler counties. During summer 2003, 3870 total trap-nights resulted in 137 rodent captures. Organ and blood samples were harvested and ELISA analysis was used to detect seropositive animals. The white-footed mouse (Peromyscus leucopus) accounted for 77% of total captures with approximately 10% of P. leucopus captures seropositive for Blue River Hantavirus. Thus, 8% of total rodent captures were seropositive. 81% of seropositive rodents occurred in oak-hickory forest with the rest in peridomestic and disturbed grassland habitats, respectively.
