Appendix 1—table 8. Posterior estimates of Omicron BA.1 viral trajectory attributes by symptom and antibody titer.
Estimates are posterior means with 95% credible intervals.
| Trajectory attribute | Variant/immune status | Estimate |
|---|---|---|
| Peak viral load (Ct) | Omicron: Low titer, no symptoms | 26.1 (25.2, 26.9) |
| Omicron: Low titer, symptoms | 24.8 (24.3, 25.4) | |
| Omicron: High titer, no symptoms | 26.7 (25.9, 27.5) | |
| Omicron: High titer, symptoms | 25.9 (25.4, 26.5) | |
| Peak viral load (log10 copies/ml) | Omicron: Low titer, no symptoms | 6.5 (6.3, 6.8) |
| Omicron: Low titer, symptoms | 6.9 (6.7, 7.0) | |
| Omicron: High titer, no symptoms | 6.3 (6.1, 6.6) | |
| Omicron: High titer, symptoms | 6.6 (6.4, 6.7) | |
| Proliferation time (days) | Omicron: Low titer, no symptoms | 4.3 (3.8, 4.9) |
| Omicron: Low titer, symptoms | 3.6 (3.3, 4.0) | |
| Omicron: High titer, no symptoms | 3.8 (3.4, 4.3) | |
| Omicron: High titer, symptoms | 3.8 (3.4, 4.2) | |
| Clearance time (days) | Omicron: Low titer, no symptoms | 7.4 (6.7, 8.1) |
| Omicron: Low titer, symptoms | 8.7 (8.2, 9.3) | |
| Omicron: High titer, no symptoms | 6.4 (5.8, 7.1) | |
| Omicron: High titer, symptoms | 7.1 (6.6, 7.5) |
