Long-Term Hantavirus Persistence in Rodent Populations in Central Arizona
Figure 4. Ranges and trap stations of hantavirus antibody–positive Peromyscus boylii during high and low population densities. Each web covered 3.1 ha. Trap stations within ranges were occupied by antibody-negative and antibody-positive mice at various times. High densities represent 13 months (June 1995 to June 1996), and low densities represent 13 months (September 1996 to September 1997).
