Table 5.
Period prevalence and infection rates were calculated from the longitudinal diagnostic records of (re)captured individuals of the six rodent species.
| Rodent Species | Period Prevalence (Number Infected Animals/Total Tested) | Incidence/Month (Number of New Infections/Uninfected at First Capture) | Force of Infection λ/Month (SD) 1 | Median (IQR) Days to Infection from First Capture |
|---|---|---|---|---|
| Akodon cursor | 0.125 (4/32) | 0.147 (2/3) | 0.24 (0.195) | 70 (26–124) |
| Holochillus sciureus | 0.425 (17/40) | 0.139 (5/8) | 0.22 (0.124) | 41 (41–63) |
| Necromys lasiurus | 0.337 (28/83) | 0.283 (10/15) | 0.47 (0.208) | 46 (41–50) |
| Nectomys squamipes | 0.615 (150/244) | 0.130 (43/62) | 0.22 (0.055) | 52 (32–114) |
| Oxymycterus dasytrichus | 0.327 (16/49) | 0.190 (8/13) | 0.29 (0.138) | 93 (44–141) |
| Rattus rattus | 0.277 (41/148) | 0.110 (11/25) | 0.15 (0.053) | 53 (41–133) |
| Totals a/mean (95% C.I.s) b | 0.430 (256/596) a | 0.141 (79/126) a | 0.27 (0.049, 0.481) b | 59 (21–97) b |
1 Coefficients were estimated from longitudinal follow-up data using Equation (2). Only animals whose PCR/qPCR was negative at first capture were included in this calculation. Values on the last line represent (a) the proportion of the total counts; or (b) the mean and 95% C.I.s of the species-specific proportions (b).
