Maximum-likelihood parameter estimates and 95% confidence intervals for the joint HPV prevalence and seroprevalence model.
| parameter | value | 95% CI | definitions |
|---|---|---|---|
| λ0 (1980) | 0.51 | (0.43, 0.59) | force of infection coefficient for 1980 birth cohort |
| γ | 0.41 | (0.29, 0.52) | HPV cervicogenital clearance rate (yr−1) |
| σ | 0.74 | (0.62, 0.86) | seroconversion rate (yr−1) |
| ω | 0.048 | (0.035, 0.061) | rate of waning immunity (yr−1) |
| ν | 1.06 | (0.75, 1.36) | rate of entering latency (yr−1) |
| μ | 0.53 | (0.28, 0.77) | rate of reactivation from latency (yr−1) |
